Wow...impressive, thank you for posting, i sent you a PM regarding my wife's car :)

[wingzero_]

Very nice, you will have me as a customer as soon as these are ready to ship.

[Derrick_B]

Any chance we can get some more videos/sound clips of the exhaust in everyday situations (idle, startup, drive-by's, etc)? A low-quality clip of an echoing dyno area doesn't help me a lot, lol.

[CorkSport]

I should have some up on youtube soon and I will post up the links when I can. I don't have a set of the driving away yet.

DerrickNice. I'd still like some outside and off the dyno, but those help. It doesn't sound like the exhaust is raspy and I can't hear a gurgle. The intake sounds pretty aggressive too. Count me in if it's competitively priced.

[Dubcnea]

these are sounding good thus far. after having a borla on my '06 i have a much found respect for mazda in the way that the cars are able to still sound good and not like a bumble bee in a can. it's much classier and sounds SO much better...the borla plus fujita intake was excellent. i did get a gurgle tho with the CAI. it was not a short ram either.

but if you are progressing as the vids show and the 'real world' vids are good then i'd say you have some sales coming :)

[CorkSport]

We will get the real world clips done in the next few weeks and post them up when we have them done.

[snowboardpunk]

about how much would this cost? and wow u live in vancouver, wa too =-) wheres a good dealer in our area to get a mazda 3? thats pretty cheap and easy to haggle with lol. first new car =-)

[Derrick_B]

We will get the real world clips done in the next few weeks and post them up when we have them done.
Update? Any closer to production on these? What about those videos?

[CorkSport]

I know our product engineer took some videos today. I will ask him about posting them up so I can get something to look/hear.

Derrick

[Derrick_B]

Nice. That's what I was looking for. Hope to see these for sale soon!

[CorkSport]

I have some videos for everyone of the exhaust system system under various conditions

Sweet results. (thumb)

[Captain KRM P5]

good work derrick

[Dubcnea]

any chance of seeing one with the duel exhaust feature? or will you be having that? i'd feel kinda weird driving it around with just one pipe when the rear is fitted for 2.

also do you know about potential prices for the exhaust and the CAI?

[PCspeed3]

sounds nice, good work CS.

[CorkSport]

We had to make a revision on the dual setup. It is coming but it will be a little later this year.

We don't have any driving video clips of the dual system. I hope to within the next 3-4 weeks.

Ouch. That bites. I really like the dual exhaust and I'm willing to bet most people want it for their 2.5's over a single. An empty spot in my bumper isn't something I'm willing to live with. So, I guess I'm out for now, unless you want to make me a new rear bumper too :D As soon as you have an ETA on the dual exhaust, please let us know...

[wingzero_]

As long as the dual is coming, I still plan to buy one.

You didn't see any torque management issues? When I dyno'd my new daily driver (3 GT, 6sp) we found great results on the first dyno and then after that, the ecu stepped in, closed the throttle down and restricted output.

I agree 100% that the engine is underrated. I dyno'd on a Mustang and got 151 whp in 4th gear. A SRI netted 15 whp before the ecu stepped in and cut it down to near stock levels on all subsequent dynos. No CEL, just robbed of power. It really took the wind out of my sails at that point. Though I will say the first dyno sounded and felt awesome.

Was your test on a manual or automatic? Did you notice anything like this?

[Dubcnea]

if that is the case due to the 'smart learning' of the engine i'm going to be pissed. what is the point of having these bolt ons if you can't use em. the sound is great, but i want performance. is there anyway to bypass that BS?

If that's the case, then an ECU flash would take care of it. The ECU would still learn, but it would expect different input values than stock, so the learning would be minor by comparison. Correct?

You could flash if someone has the capability to flash it. COBB is supposed to be working on it, but they might just stop after the Mazdaspeed 3 again. I know of another company trying to work through it, but torque management can be a nasty thing to work around.

As for bolt on mods, the engine responded BEAUTIFULLY to them at first, big gains on an engine that is already under-rated. I had a shit grin on my face after the first post mod dyno pull. . .and then it all went down hill. As I stated, mine was on a fully loaded (not that it should matter) GT, 6sp. I'm curious what they tested (looks like a GT). Also how many pulls they did after the mods.

I'm tempted to dyno again to log as much as I can via my AutoTap, but the results won't be any different, I can hear the difference between what it does now and what it did before the computer stepped in and ruined my day.

[CorkSport]

Actually we did see the ECU being very active in all of our Dyno pulls. We did a minimum of three pulls per baseline and/or modification and the main thing I saw that was radically different between some of the pulls was the air fuel ratio. While we did not monitor actual throttle angle on all of the pulls, I doubt that the drop in power that you may have seen was due to the throttle shutting as much as it was due to the ECU editing fuel and/or timing.

What we specifically saw on stock was the first pull was really jagged (smoothing shut off in all reviews of the files), stock ECU runs really lean (~14:1) until about 4500RPM and then drops markedly to ~10:1. Subsequent runs go rich sooner, dropping into the high 11's in the ~2500RPM range. This smooths the midrange power numbers and they go up and are less choppy. The numbers on the three stock baseline pulls (2.5L, 6speed) are 161.46, 163.90, 164.23. That is the peak power.

Comparing this behavior directly to the same car with Short Ram Intake and Dual 60mm exhaust system, the three pulls do indeed go down in power from the first to last - but the overall amount of decrease is less than 1hp. In addition to this, the radical fluctuation of the air fuel ratio during wide open throttle (WOT) runs is not remotely as reactionary as it was during the first three baseline pulls. The best of these pulls (second when looking at torque and hp) is 171/171.

I think what we may be seeing while dyno testing these cars is that the ECU is having to adapt to a WOT at load condition that it has not experienced in the past and we're just seeing the learning - sometimes it shoots one direction (rich vs. lean) and has to lean out to hit its assumed target, other times it shoots the other direction (lean instead of rich) and has to richen the mixture to hit the target. The results are not always negative relative to power building. Best to Worst, Worst to Best and Best to Best, the modified cars built more power. Days later on the butt dyno, the car was just as good if not better than it was when we had rolled it off the dyno after we did the pulls testing the intake and exhaust in tandem.

That being said, I do not have any doubt that having some access to tune the parameters set in the ECU would improve greatly the potential to build power in these cars with the aforementioned modifications. I know that with the MS3's, they need to be run for an extended period of time after a new induction system has been added prior to tuning the ECU so they may calibrate the MAF, then tuning can be done. I think we may very well be seeing similar behavior in our test results (and yours).

Thanks Jason.....Good info. When do you think the intake will be ready to ship? I can beta test if you like :)

[CorkSport]

Jason hi-jacked my account to answer the question above.

I will have to confirm this but the SRI should be ready on August 24th.

Awesome. It's definately on my list. Any suspension parts in the works? I'm 90% sure the 04-09 RSB fits, but what about the FSB? Springs?

[Dubcnea]

i hate to be THAT guy that keeps asking...but do you happen to know pricing for these parts yet?

You can pretty much assume it is going to be on par with every other intake and exhaust that has existed.

Just throwing a guess out there:
Intake anywheres from 199 - 350. But because it's a SRI, ~250+
Exhaust, single tip 499-699, Dual Tip most likely 799+.

[Dubcnea]

any updates? :)

[twowings]

Is your goal maximum HP or torque/driveability ? I would much prefer emphasis on bottom-end/midrange than drag-race capability .....

[Derrick_B]

That's a good question. I would say they're trying to give us more power across the entire powerband, since that's what their dyno shows.

He posted the price on the other site. 179 for the Intake.

[Derrick_B]

If that's accurate, the price is definately right.

[CorkSport]

$179 is correct for the intake.

[wingzero_]

$179 is correct for the intake.

And we are looking for the release of the product to be this fall?

[CorkSport]

We have just posted up the cat back exhausts for the 2010 Mazda 3 2.0 models. We have the exhaust systems in stock and ready to ship out.

Click here for a link to the CorkSport webpage exhaust listing (http://www.corksport.com/corksport-power-series-exhaust-system-mazda-3-2-0-model.html)

The intakes for the 2.0 and 2.5 are next.

-Derrick

[Derrick_B]

Awesome! Can't wait for the intakes and 2.5 exhausts (yippy)

[Mazdaboysp23]

Me either!!! Can't wait!!! My 2.5 sounds like a civic hybrid LOL!!!!

[CorkSport]

We just received in the air filters for the intakes today. They are the dry flow media but they have a new twist to them which I will share later this week.

A guesstimate will be end of next week for having the intakes ready to go for the 2.5 models.

I will have to check on the 2.0 models, they require a different MAF housing and I know they are being machined up.

-Derrick

[Mazdaboysp23]

They are the short ram intakes right??? I'm so excited!!! Congrats on the new Speed 3 by the way!!! I love my 2010 gt!!(silly)

[Mazdaboysp23]

So are the 2.5 intakes coming out this week??? Any news for us???

[Derrick_B]

Not 100% sure. Check the CS blog tomorrow (Thursday). The intake are definately SRI's though.

[Mazdaboysp23]

Cool, thanks for the response, I can't wait!!
