    Default 205 gti6 exhaust diameter - road car

    People throw 2.25 around as a good number for a modified gti6 motor. as a road car with a standard engine, seeing maybe only stage 1 cams and standard management, is a 2" exhaust sufficient for flow as is and to keep it as quiet as possible for a road car? had a 2.5 on my mi16 1.9 and that was standard, and that was loud.

    I think 2.25 is standard on a gti6. Correct me if I'm wrong. Just get a good middle straight flw muffler and a big box at the back with a 2in tip and it should be fine.
