Nah I understand where you are coming from, I'm thinking about buying a set myself and coupling it with a catless catback. I'll know sooner than later. |
I am considering getting a stillen cat back and some test pipes and seeing what happens.... the 370z y pipe is super restrictive and anything prior to the flex joints i feel are gonna be a negative until you can open the y pipe up.
I am talking with r2c intakes right now about testing there intake, so i might splurge on a stillen cat back in the next month and not sure what brand test pipes yet.
Main reason for doing headers first was to get the PIA mod out of the way first.... only n/a install that is gonna be more of a challenge if i do it is cams and only exhaust cams seem to be a viable option but that will depend upon intake timing options.
