so im gettin a borla pro xs muffler with a magnaflow cat and two 2 3/4 pipes and was wonderin what yall thought of those mufflers? i had one on my last t/a with a 305 but it had 2 1/4 inch pipe. how diff should the 350 with bigger pipe sound?

 

borla is high quality muffler and i think it will way better with a 3 inch piping. and youll see a big difference.

saw a pretty good change, 10 hp probably, and it sounds perfect not too loud but with a performance ring to it I love it.
