I got a 97 GSR with a Greddy turbo kit. How good is the Thermal exhaust 3" system, and do any company offer a downpipe that is bigger than the puny 2" unit i got with my turbo kit?

 

you would get great results with the thermal 3" but no one sells a dp for Greddy turbo kit so you would have to fabricate one at a muffler shop.

 

Thanks Mike. Right now i have a DC Sports 2.25" Catback and a test pipe. How mutch boost can it handle before it begins to be a restriction?

 

that exhaust would be alright for boost, a lot of people run stock exhaust for temporary use until they get a straight through free flowing exhuast. Just try to get a bigger exhaust when you get a chance to, because it would be alright to stick with a small exhaust just you know that you could have so much more power, having a restrictive exhaust might cause too much back pressure and hurt your turbo.

 

For anyone with a turbo I suggest the Thermal 3". It is a beautiful piece, full stainless steel piping, and just a very well made exhaust. You can easily have someone fabricate a downpipe for it. I don't know what way you are going ,but you can get a straight pipe for it as well. But I would recommend a high flow cat since the Straight pipe is illegal in most states.
