So i have catted downpipes with x pipe and mbrp quad axel back.The idle and sound of the car is perfect for me but I wanna go louder but I’m scared I’ll mess it up if i go with a second cat delete. Any opinions or someone that has this setup? I'm trynna see if someone has the same setup just with the second cat delete so i can see how it sounds when just driving by/ cruising / and full throttle.

i have my second cats deleted, no x pipe, flowmaster axle back. i do it for the free flowing aspect. i didnt notice much difference in the sound with the cats deleted. now if you did your primary and secondary then it would probably be much louder.

I'm going down the same route but with a cat back exhaust. Are the secondary cats just forstartup until the primary cats get to operating temp? Worried about failing the sniff test.

if you want loud and no cheap sounding rasp, get a true x put in an mrt v2. Keep the cats.

also, hope you don't drive it on long treks and plan on adding dynomat even if you don't.
