I'm in the market to purchase an S2000 and would like to know the LOUDEST single exhaust system made for the S2K. I know that the R1000, J's Racing, Megan Drift Spec, and Invidia people say are the loudest.
Would I have to worry about not passing emissions with any of those exhausts?
If so... Is there an exhaust someone could recommend me getting that's loud as piss and I can pass emissions with?
Someone help please!
