Did you email David at Borla? He'll tell you if something is coming, but I agree with Tony - doubt it.

Put on the GM option Borla today and immediately noticed a difference in throttle response and engine "smoothness". It's dual 2.5" pipes out of the muffler and a 3" into it.. There's maybe 3ft of 3" piping after the cat, so that'd be the only place to have 3.5", which is the same size as the piping it connects to after the cat. Not sure a 3.5" exhaust would be much of a benefit

Two 2.5" pipes = 9.82 sq in and one 3.5" pipe = 9.62 sq in of flow area

I'm willing to bet there's a legit reason why they didn't put 3.5" pipe on it before the muffler.

Perhaps.

I believe it's due to cabin sound or something. The 6.2 trucks have a 3.5" borla.
