3" PS Y-pipe no more
Well third times a charm. I never really liked the 3" PS y-pipe. I always thought it was too much for my little 5.3. Well..... I think I was right. I went with a true dual exhaust. Starting with my PS headers into 2.5 pipes. Each pipe is going to its own high flow cat before entering a magnaflow x-pipe. Then each pipe has its own magnaflow muffler, straight through design.... up over the axles and both pipes dump up high so you cant see pipes when truck is on the ground.
The throttle response is sooo much better. It pulls much better from a roll now too. Amazing how much difference an exhaust will make.

thats the next plan to get proof on dyno. But no mistaken the difference Im feeling. Its not a small difference.... its night and day
My old exhaust was 3" PS y-pipe into single 2.5 pipe... into single in 19" magnaflow dual out. This was much louder and less responsive. I originally didnt have any cats, then added one and seemed like motor liked added back pressure
