Default cat-back on TT 427

Since I am customizing an exhaust for my car, I am wondering if I would benefit from going up 0.5 an inch on both pipes from 3inches to 3.5inches. Would this change help reduce after-turbo backpressure by anychance?

I dont care about low-end power

Considering the size of the turbos I don't think you would gain anything over dual 3in. A single 3in downpipe is good for about 900rwhp fwiw.

Thanks Jim, I might experiment anyways, or maybe not still didn't make up my mind.
