Most everyone's missing the point, he's going TURBO you need 3 inch piping and should highly consider 72 MM canisters to help with exhaust flow unless you like back pressure build up......ALL THE TIME

 

I would say get whatever exhaust that you like the best and get an electronic dump valve installed on the end of the downpipe. IMO I would still get the most free flowing exhaust I could get, and still get the dump.......But that is just me

 

PM AHHVTEC about the Spugen pipe.

Spugen made a custom setup for my S and my xA:

what if i get one of the ultimate racing 3inchers and have them weld on ovals instead of the round ones they use on their web site??????

 

you can do that but ultimate racing won't i bet

my explanation is take off stock exhaust. take off stock cat. replace cat with test pipe. get o2 simulator so you don't see check engine. weld on a honda flange on your custom made 3 inch exhaust make brackets alone so it'll just slide right in.

you can get this and that exhaust systems. but the main point you want is a exhaust that has 3 inch pipings from the cat converter to the out hole
