There are a lot of different exhaust setups you could choose, and sound is really a matter of personal preference. I got the Thermal R&D because I really liked it when I saw and heard it on someone else's similar setup.Krystal'Speed said:Roni - The Thermal exhaust tip you're talking about, where could i find one? I wasnt thinking about going any bigger than 2.5" on her exhaust either.
Oh, okay, I see what your saying about fuel efficiency. When you were talking about the yield I thought you were trying to make a point about hp.DAWIV said:Well, let me clarify. It was alleged that going catless would burn more gas...it does not. And what you believe don't mean jack, the car is quiet with a catless downpipe and the Greddy exhaust system. Its virtually as quiet as the stock set up.
Pretty sure all the exhausts out there put the cat on the dp if anywhere. So a catless dp is a catless exhaust. I could be wrong though.roni said:Oh, okay, I see what your saying about fuel efficiency. When you were talking about the yield I thought you were trying to make a point about hp.
Umm, you were saying that cat-less is the only way to go, and I just realized that you were in fact referring to a catless downpipe, not specifically a cat-less exhaust system. You were saying that in am emissions state you wouldn't be able to go cat-less. I would think that as long as you still have a high-flow cat in your exhaust, that you could probably get away with a cat-less dp, but don't quote me on that.
I guess I misunderstood what DAWIV was saying when he says he is catless on the downpipe but has a full Greddy SP2 exhaust system which from what I understood, is a full exhaust system with a cat on it. I obviously missed something.peepsalot said:Pretty sure all the exhausts out there put the cat on the dp if anywhere. So a catless dp is a catless exhaust. I could be wrong though.
Dean has this on his MSP. Contact MPI for more info if you are interested. Ask for Nick 732-222-3679.spacemonkey said:I would actually opt for the hi-flow cats for daily driving. It may present some back pressure but not as much as stock. And some back pressure can save you gas as your turbo doesnt spool up as fast.
let me show you what I plan to do:
QTEC electronic cutout...and electronic downpipe. At a flip of a switch she can run sort of an open exhaust deal (race gas,loud and etc). And when she wants she can close the valve for a stock noise car and be daily driven.

Get an exhaust shop to weld it onto the DP...there was a group buy for this but im not sure if its going down anymore because there was not much interest. One a turbo car this is probally one of the funnest mod and the turbo will probally spool up very quickly. The WRX they tested on gained 22 whp from it. On some NA cars its not good because you need some back pressure.
Currently doing more research ont his productbecause I dont think any MSP has it on. Its popular among the domestic guys...so I'll probally ask them if they recommend it or not.
Thank you thats probably the best for my gf's car right there. If thats all going to be emmission-safe for a daily driver, b/c we all know how much CA emmissions is.warrier04 said:** Airflow Logistics Air/Fuel Controller (PM DSMConvert for more info)
