Re: Which 3" exhaust to compliment APR Stage 3? And intake? (Foxman)

That is a valid point, but, since they do produce a 2.5" cat-back system, they more than likely used it in the tuning/R&D process of the stage III kit. Thus they would have tuned the kit to perform optimally with a 2.5" exhaust system. That's the way I would do it.[HR][/HR]
Their 2.5" turboback was R&Ded on a car with a stock K03 turbo, and they'd need to compare it to a 3" on a stg. III car to really know. Also, I think Stg. III was developed and released before their exhaust.
