I'll start off my telling you my plans for turbo. I'll be at no less than 6psi and no more than 10psi and I'm shooting for no more than 200hp in my coupe. So what my question is, would i benifit from a 2.5 or 3 inch exhaust? or would I be better going with the regular 2.3 aftermarket exhaust for those kind of hp gains? I have done quite a bit of researching and it seems like people only use bigger exhaust piping with higher hp applications. If I were to get a 2.3" exhaust I was thinking about the apexi ws2 or the greddy sp2. does the greddy have any advantages over the apexi? Any help would be appriciated, or experiances or anything. thanks!


Thanks for the advice

3 inch would probably benefit a turbo the best

But even though I am only shooting for low boost?

no it wont. a 2.5 will be the best bet for you. a honda at low boost dose not need that large of an exhuast.

^that was kind of what I was thinking. isn't it because the 3" wouldnt create enough back pressure? Would I need a high-flow catalac converter with a 2.5 inch exhaust? thanks

you dnt need a high flow cat, that is you prefrence. And as far as back pressure that would play a role in it but also having a 3 inch exhuast would do nothing for you really.

No point to 3 inch piping for that amount of boost. Save yourself some money and go with 2.5.
