magnaflow exhaust

[lncatch]

is anyone runnin a MSP with a magnaflow exhaust?? how loud is it, any significat power increase in HP or torque? and does it bolt right into the stock downpipe?

i have a magnaflow muffler, but not the cat-back exhaust, i got it custom done at a local shop...

magnaflow's is just a catback. it bolts up to the second cat. run a search for "aftermarket exhausts" and you'll find a thread i started with soundclips/vids of an msp w/ magnaflow catback.

i have the cat-back magnaflow and i am happy with it. it isn't too loud but i think you need to get a full turbo back to get louder. the sound is deep and i have notice it pulls harder at higher rpms then it did before the exhaust

[Hypnotized]

Isnt the magnaflow the same I/D as the stock exhaust??

Yea it's 2.25 ID piping. Buy the one for a mp3 its the same and cheaper price. It fits the stock catback section. We test fit it on my car before we put it on a MP3. Sounds okay not much louder than stock. Minimal performance gains. Cats still block the flow.

Wait...so the Magnaflow exhaust is not really an upgrade in piping? I thought the stock exhaust had a 2" ID. If they're both the same size, is there really a difference?

get a JIC. From what i hear it is the best sounding exhuast period. Since i never got my greddy SP2, i ordered a JIC a couple days ago from AutoRND. I can't wait to see it and hear it. but i still need an engine first.

I appreciate input, but if somebody could answer my question, I would really appreciate it.

I have done several searches, but I am seeing a lot different information. It seems that people are saying a lot of different things about what the pipe measurements on this system. So if somebody could just settle these questions for me once and for all, I would be really grateful:

1. What is the MSP stock exhaust's piping size (inner and outer diameters)?
2. What is the piping size for the Magnaflow system (inner & outer diameters)?

Thanks!

Stock exhaust mid section is 1.8 to 2 inch. Racing beat rear section is 2.25. Get a downpipe and the Magnaflow for the best results.

Okay, so the stock exhaust system has a 1.8 - 2.0 inch downpipe and 2.25 inch exhaust.

Does anybody know the true answer to question number two?

Thanx again!

[JDM Sam]

2.25 all the way till it tapers down some at the flange where it bolts into the stock cat section.

I built a custom 3" exhaust with a magnaflow muffler. . .the sound clip is in my sig. . .I think it is the best sounding exhaust option. . .but that's my opinion.

[Matrix]

Hmmm, the Magnaflow doesn't really seem like an upgrade then. If I'm going to spend that much, I'll have to look for a larger piping diameter.

I'm thinking Greddy SP2, or maybe EVO2.

Thanx for all your help.

Anything over 2.5 is overkill on the stock turbo at 10 psi.
