gonna try to install tues on my day off. Ill post pics

Where did you get it from and how much?

[Adammazda06]

i'm glad to see that mazda did'nt push them back again. i called mazda on monday to verify they would be released to the warehouses this week. mine should be here on monday, and i cant wait. with all good luck mine should be on monday night. check with your local mazda dealer to order. not very many to go around.

[Mspeed3]

list price is 729.00. got mine for 650.00 with free installation from dealer

[gsrtype1]

can you posts pics and some sound clips and is the exhuast 3 inches?

[Mspeed3]

exhaust is 3 inch and beautiful. Ill post pics of it tomorrow installed late tonite. The sound at idle isnt much louder. It does have a little bit of growl to it especially if you goin fast in a low gear and let off gas. But much like the mazdaspeed suspension its performance over look/sound. I could really feel the power increase

[staples187]

Is there a resonator associated on the exhaust? I'm looking to go resonatorless but of course the muffler, I was looking possibly GHL.

Sweet can't wait for pics and vids!!! (burnout)

[07speed3]

Thats great so you can definitly feel a power difference with only the catbac...hurry up with those pics and vid!

[~JoJo~]

i am new to this, but doesn't mazdaspeed3 comes with mazdaspeed exhaust? What's the different?

[speed3shon]

the stock exhaust is 2.5"...

the mazdaspeed exhaust is 3"

[BSTD3]

Is the MS exhaust just a simple unbolt the stock exhaust and bolt on the new? Two bolts and some hangers correct?

[~JoJo~]

i am assuming there is a sound and performance different also?

[stars.eg6]

not quite that easy but yea you have to cut the stock pipe right before the rear axle and then unbolt everything while trying to wiggle the hangers out of the rubber and then after all that fun you just bolt the new one right up.

[D_Roc7822]

yeah I cant wait to see the exhaust installed and everything... and some sound clips would be pretty awesome.

[sgon]

I posted this at the other forum

So there is no way to remove the stock exhaust without cutting it?

[whitey4311]

That sounds 10x better then the other stuff I have heard around here. I think it sounds better then the CPE for sure and isnt as obnoxious.

Is there a noticable power increase at all?

Nice!

How much and where?

PS now take that gay shit off the front end.

[ill_eagle94]

There has to be a way to remove the stock exhaust without cutting it off. (dunno)

[stars.eg6]

well if you dont want to do it the easy way this is how it goes.
"The service manual says you can remove it in one piece. To get it out in one piece the instructions say:
1) Remove the rear shock absorber lower bolts
2) Loosen the rear crossmember component installation bolts (6 locations) and lower the rear crossmember component approx. 70 mm {2.8 in.}.
3) Remove the main silencer."

That doesn't sound too bad. Since I'll have the car on a 4 post lift, this should be a snap.

yea its not so bad but i was just working on my back the whole time and plus i wanted to be able to store it easier so i just cut it.

[RelliMS3]

that does sound pretty nice. does the noise get at all annoying at highway speeds

[BSTD3]

Sounds pretty SCHWEET! Gotta ask the wifey for a new mod :)

[civic si hb]

Sounds really sweet, kinda suby like at low rpm. I might hop on this as long as the install can be done with out cutting anything which does seems to be with a lift.

[Craighjr]

A lift would make it worse to remove whole. The six bolts are holding the whole rear suspension on the unibody I believe. I haven't done an exhaust on my Speed 3 yet but, that is the way it was on my Ford Focus. Once you remove the 6 bolts you need to hold up the whole rear suspensions weight. I'll assume that if you have a lift you have a trans jack but, I would count on the rear balancing that well.

[SwampAss]

or an alignment lift

[Speedy3]

Got mine yesterday, but had to drop it off at my friend's house. Wife doesn't know I dropped 6 bones on another upgrade. she would kill me considering how much I ragged on her for spending $400 on Victoria Secret bathing suits. I'll try to Dyno it after install.

Pics of the exhaust and your wife in the bathing suit please :rolleyes:

[whitey4311]

Why do people say that the CBE doenst do much for performance and that its an expensive upgrade with little gains?

I was thinking about getting one but I keep hearing this and also cant imagine how the major difference being that its only .5 inch larger doing a whole lot. The stock pipes are all mandrel bent just stock so I dont know that there is much room for improvement.

[Kosh]

The real restriction in our exhaust is the cats. High flow or test pipe will help this. Once you take that restriction out then the gains from going to 3" will be better.

[knowledge007]

CBE is nothing but a waste of money. YOu need to replace your downpipe. You want some real gains, how do you expect gains if your downpipe still has two cats and is less the 2.5" hooked up to a 3" inch. What gains could you possible feel. 729 for CBE is a rip...

[gsrtype1]

the mazda speed cat back loooks nice, but its seems not that loud , i like the way the cpe catback has that loud angry, agressive, sound

[Kosh]

For turbo cars with around 250 hp like ours 2.5" is plenty of width. For going over 300 hp 2.5" is too small and 3" is needed. Go up to 400 hp and 3" is too small.

Cats = Bad

Performance > Sound/Look

Check out the exhaust theory (http://www.mazdas247.com/forum/showthread.php?t=67805) thread for turbo applications.

[whitey4311]

thanks for saving me the money guys I get it now.

[ALIEN3T]

if my wife spent 400 at victoria sectrets. means she woudl or will spend 500-600 on me. plus she has new bathing suits!!! (but prefer the other stuff from there).

if and when yo do drop the rear. dont unbolt the brakes cables. or line. that will keep it from falling or help ! but all you need is a few jack stands and a jack. and possible if you have them run the fron tires onto ramps use stands in the rear! so you have the extra room to work. and drop rear sub.

[gsrtype1]

every body has an exhuast "theory" the only thing that is believible is a fair dyno before and after , than you'll know the truth

[knowledge007]

What are you talking about GSR. WTF theory are you reffering to??? Its plain and simple. CBE is shit. Be a man replace the full exhaust.

[gsrtype1]

yeah maybe your rite it just seems like i hear so many different ideas , like one guy on here said he installed a down pipe and lost power. ? ...

[knowledge007]

of course b/c he hooked it up to the stock CBE I am assuming. I think he was the one who ended up buying the CPE CBE and hooked it up to to the test pipe right???

[Kosh]

Exhaust theory isn't something someone just pulled out of their ass... it is based on research done since the invention of the internal combustion engine. Everyone can't go out and purchase every exhaust on the market and compare hp gains on their cars...that is why you have to go on what other people claim as gains to make your choice as a consumer.

[Kosh]

Don't think replacing the entire exhaust is necessary. Gains won't be worth it by going from 2.5" to 3". High flow cat is where it is at if you are worried about passing emissions or go catless and put the stock exhaust back in when you need to go in for testing.

[gsrtype1]

i was going to buy a cat back , after saving enough money , but i think i'll just remove the 3rd and final resinator and at leat ill have 21/2 inch straingt pipe, the later on ill get a full turbo back exhuast

What are you talking about Kosh. I replaced and yes it is necessary if you want some monster power gains. Anyway, here in florida we don't have to worry about testing.

[Kosh]

What are you talking about Kosh. I replaced and yes it is necessary if you want some monster power gains. Anyway, here in florida we don't have to worry about testing.

The monster power gains are coming from the high flow cat and not so much from the diameter of the exhaust. Bigger exhaust is always better for forced induction but there is a point where you won't see any more gains. With only cold air I really doubt you are pushing enough exhaust to see monster power gains from going 3"

Say you are planning on droping a bigger turbo in there then I totally see how 3" would be worth it. Hell when I'm ready to work on exhaust I'll probablly go 3" as well since I want to take my car well over the 300hp mark.

But I'll probablly start with just catless DP for immediate gains and wait until it is more profitable to go 3" down the rest of the exhaust.

[knowledge007]

Now that is something I can't do... If anything ever happens and the car need to be checked, atleast I have a high flow. MS6MIKE has the CPE straight pipe with resonator and that shit is loud and smoky...lol And I thought I was loud...you have seen my vids...

[Kosh]

I'm still undecied between straight pipe and high flow. Corksport DP looks pretty good to me too. 1 cat so it looks more legal than catless. But I don't know...Don't want to get one thing and want to upgrade later :(

So many parts and so little money (stooges)

[SwampAss]

the decision is easy for me. Cat. I have to have it. I have emissions testing every 2 years. I sold my GTI because it failed and didn;t want to put the money up to get it to pass. It was cheaper to take the loss.

[BSTD3]

SOMEONE IN THIS ROOM IS A MURDERER! That kills me! :)

sorry i was posting two threads at the same time...i meant to post that somewhere else but typed in the wrong box!

[Haltech]

Turbo 4 cyl's sound different the NA 4 Cyl's... I think these cars sound more like a WRX with a new exhaust. At least with those, i have heard. Im ordering the GHL next week but was hoping Ken was going to become a supplier for them.

[Craighjr]

So can someone take a picture of the exhausts first section? I am interested in the dp to cb joint. Basically I want to know if a CP-E DP will not leak with a MS CBE.

I don't see why it wouldn't fit up with cpe down pipe. That's also the combo that i'm looking to do in the future too.

[Adammazda06]

here is the mazdaspeed exhaust. just came in today and hopefully it will be put on tomorrow. i will get some pictures of the install. looks simple with the exception of having to cut a small section out with a hacksaw.

[bast525]

Think I'll save my $700 and wait for Cobb's AccessPORT to come out... or put that money into a better TMIC... both which are making really good hp gains on the dyno's I've seen/heard about.

TMIC will be cheaper, easier to install, and I think guys are getting 20-25 hp from this mod alone?

AccessPORT is supposed to bring a stock MS3 with no other upgrades up to like 290 whp, and is just plug it in, flash and go.

I also agree that the stock exhaust is loud enough for those of us who don't want the attention.


I know we have to wait for a back to back dyno of stock vs. cat back, but I doubt it will make that much power.

Case in point - Sport Compact Car magazine dyno'ed a bone stock MS3 and then one that had the cat back and MS CAI, and gained about 15 whp.

By comparison, many people here have dynoed with the stock intake and then just the CAI, and gained anywhere from 10-25 whp. Which tells me that in the Sport Compact Car comparison, the intake made the majority of the difference in power.

I'd be very surprised if a catback made more than 5-10 hp. It will speed up turbo spool which will make the car 'feel' faster and more responsive, for sure. But as others mentioned above.... for real power you need FULL exhuast, turbo back.

When you are done can you get pics of all the pieces of the stock exhaust layed out like you have the new exhaust. I am interested in seeing how it looks all nice and disassembled :)

[Adammazda06]

Think I'll save my $700...

wow thats high for the exhaust. i got mine for $475!
for those interested, i will get full install pictures tomorrow or sunday.

[uncletime]

where and how did you get yours for $475?

[Adammazda06]

where and how did you get yours for $475?

i work for a mazda dealer. 475 is cost. full list is 699 i think. parts are negotiable just like cars. just work your local parts departments. keep in mind, this is a very limited part. on the mazda parts order screen it only show 42 at the warehouse.

[whitey4311]

So is this CBE worth getting or not?

Going to the dealer tomorrow and have a 15% off card from when I bought the car but the parts guy was a dick last time and wouldnt let me use it with out mkaring up the cost for the CAI.

I will have to look into it and beat the shit out of him if he tries this again. Sort of bull shit to get a 15% thank you for buying the car letter then when you use it they jack up the cost.

Good to know $475 is cost so he cant jerk with me on this.

good to know that cost helped. if he says otherwise he's lying. i really hate when dealerships screw over people. cause it gives the fun, easy going, laid back dealerships like mine bad names. if you have anymore price questions let me know.
and i will let everyone know how the exhaust works out sometime this weekend.

[bast525]

Wasn't there a vendor on here that tried dynoing back to back with the stock exhaust and then disconnected the cat back and saw like no power gain at all except in the very low RPM due to faster spooling turbo?

Wasn't there another vendor who also showed that a catback exhaust gained almost nothing?

I dunno for stock or moderately increased power levels... I really thing 2.5" mandrel is big enough and doubt even the better cat is going to make much of a difference.

I say definately NOT WORTH IT.

Even if you can get it for $500, you can get a bigger TMIC for that much which will gain you more power and the added benefit of less heat soak, so more power for longer, or you can save up an extra 20,000 pennies and get the Cobb AccessPORT and make even more power without installing anything.

likewise here too! after driving friends suby's with accessport, i can't wait!

[whitey4311]

What is accessport?

I realize that the TMIC may result in higher gains but I like stuff that is covered under warranty and that seems to be the MS stuff obviously. I worry that some how that TMIC will negatively differ from stock like in the rain or something and cause issues.

On the other hand I dont want to pay $600 for CBE and have it not do much for me.

I love the new sound! Install was not too difficult. Myself and one of my Mazda Techs put it on with no real trouble. Most difficult part was cutting the old exhaust, but when that was done, it was simple. Can I feel any more power? It's hard to say. It sounds great, and we all know louder means faster!

[SwampAss]

awesome pictures. Thanks Adam.

[Adammazda06]

awesome pictures. Thanks Adam.

no problem. i don't have digital video camera, but i will see if my digital camera can get some decent sound clips.

[whitey4311]

My dealer flat out told me today that the CBE is worthless for the money and didnt even try to sell it to me.

I went in for the motor mount today and figured they could talk me into a purcahse and install of the CBE but he woudlnt even sell it to me. The MS parts manager said it was very minimal gains and cost way too much for what it is compared to stock.

They also said that a TMIC woudl void little shit like the engine and turbo, lol. So looks like the CAI and tint are going to be my only upgrades unless I feel like unbolting the IC every time I go for an oil change.

[controlo]

or you could take it to jiffy lube... or do it yourself... just a thought.

btw, louder does mean faster. haha.

[whitey4311]

That is a good point to take it to a generic lube place but I like going to the dealer and I can eaily justify not spending $500 right now, lol.

[controlo]

haha, whatever you gotta tell yourself to save money. if i had 500 bucks, i'd probably get a cd deck and speakers. stock sound system sucks compared to my tC. that would suck having to take it off for every oil change though... i take my car to the dealer for oil changes, btw

[dparm1984]

Going to resurrect this thread to ask a question that no one seems to have clearly answered...how is cabin drone with this versus stock? I absolutely HATE when the exhaust is droning on the freeway.

Most of my passengers ask if the stock exhaust really is stock, so I have to wonder how much louder the CBE is while just bumming around town.

Thanks in advance.

[SwampAss]

I have ZERO drone. None. It's stock quiet until I step on it.

[dparm1984]

Good to hear. So at 70-80mph there's really no noise into the cabin? The 3 seems to have surprisingly good sound deadening but that muffler is awfully tiny.

[SwampAss]

nope. Windows down it's more wind noise. Windows up it's not noticeably louder. Give it gas.....it's apparent but not over bearing at all.

[dparm1984]

Excellent. Hopefully my tax refund will cover this. :-)

I appreciate the honesty and quick reply.

[SwampAss]

NP. Your questions were a concern for me also back when I bought mine. No regrets.

[blue-sun]

so how is this holding up?

mostly posting so I can find this thread again when I'm ready for a Mazdaspeed exahaust, likely later this year or next year.

[Silver Ecstasy]

I'm lookin at getting this as well and no one has really spoken about one since 07 it looks like.

[SwampAss]

Mine has been on for about 35k. It's a little louder but still in new condition.

[chief_wiggum]

Mine has been on for about 35k. It's a little louder but still in new condition.

so how is this holding up?

mostly posting so I can find this thread again when I'm ready for a Mazdaspeed exahaust, likely later this year or next year.

looks like I may be picking up a used MS CBE soon...if all things work out.

So inside the cabin, is it alot louder than stock? My wife's having twins in the spring, they'll mostly be in her Edge but occasionally they'll go in my MS3 so my big worry now is the noise in the back for the babies.

[Silver Ecstasy]

Blue:

It's not much louder than stock. Infact, it's less loud on the freeway and off-throttle drone is almost non-existent. However, people have told me they can definitely hear me coming from down the street, versus before where you couldn't tell until I was almost infront of the house during that off-throttle engine braking.

One friendly tip when installing the MSCBE: there is a section where the two pipes slip together and are clamped tight. There is also a line marked on the pipe showing you where they should fit. If you line it up at the marker or over it, the exhaust will knock against the car during hard bumps. However, if you pull it too far away, the clamp won't seal and you'll have an exhaust leak. I do, and still have this issue where a tiny pinhole area right where the two pipes are joined is slowly puffing soot onto the outside of the exhaust piping.

When you install it, start the car and get underneath so you can hear if it leaks or not. We had it on a lift and we started the car, then lifted it back up while it was idling and kept noticing it and adjusting it until we could get there as close as possible. Unfortunately, it's still not fixed so we may try some copper gasket spray or buy a 2nd 3" clamp to put next to the first one.

But you will not regret the throaty Subie sound that comes from this exhaust. You will however, lose a smidge of low end torque, but the higher rpms climb quicker.

[MSMS3]

This is a quality piece and definitely has a sweet sound.

Have you addressed the restrictive dp/rp first?

With respect, unless you have upgraded to an aftermarket DP/RP, there will be no power gain from this or any other CBE. The true restriction is upstream in the factory dp/rp and low-flow cats and the restriction is so substantial that opening up the CBE is really meaningless from a power point. There is no basis to expect a power gain unless you exceed 300 whp and it takes fixing the restrictions upstream. Even then, the stock K04 turbo's maximum exhaust turbine flow rate is less than the flow rate of the stock CBE. The stock CBE flows that well.

But the MSCBE sure does have a sweet sound.
