I’m curious if anyone has some insight on how much a stock NA exhaust on my recent TT swap will impact its performance. I have AMS manifolds, 3” downpipes off my gt525 turbos, and 3” to 2.5” resonated test pipes ... then the stock NA exhaust. I’m assuming it will hurt spool times, but not sure what to expect when I get a 2.5” exhaust (looking at the B&B catback).
