I have T1R exhaust and now I want something really quiet yet, with good performance gains...
Reason for looking? My parents have stereotypes on loud cars...
Back to the topic, is there any exhaust system that gives good gains as well as quiet.
T1R is similar to sunline racing exhaust.
I've had invidia gemini before, but I want something more quieter than invidia.
+ I don't have HFC nor TP and I'm not going to put silencer or resonator.
