I'm trying to quiet down my car, currently I have an Invidia Q300 with test pipes and its not a great combination.
Might be interested in your exhaust and possibly even your cats. Are you still running your stock cats or a HFC? I know the S-tune does not make alot of power, but there seams to be a lack of info on the OEM Nismo exhaust. How does it compare with your new setup?
What part of DFW do you live in? I'm in South Arlington.
