My buddy has a Greddy SP and it's uber quiet. I highly doubt you'll get anything AS quiet as OEM cause you can't even hear the freakin' car running with the OEM system.
Dam, that can't be lawful to impound your car for your exhaust. I mean, I hate TF&TF, but that guys has it out for you guys.. :down:
I'd be in a rage man... FOCK HIM! :madfawk:
