[QUOTE=Pdubinator]Yes 3" Really is better than 2.5. The best exhaust for turbo is no exhaust, the car already has enough back pressure from turning the turbine inside the turbo. QUOTE]
I was told 3"TurboBack was too big for the stock K03/K04 turbos on the 1.8Ts. That's not to say it is though. Is the 3"TurboBack worth the extra money spent? I'm more than sure it is better but how much? I have yet to see dyno charts of similar cars to compare, or even hear what they sound like.
