I have the CP-E complete exhaust system, DP & Cat-back w/2 14 inch resonators. Hope you like it loud tho, (mine stills drones too much for my sensative ears & I must be a wuss or care too much about what the WIFE thinks when she's sitting in the passenger seat) I am waiting patiently for Jordan and the guys at CP-E to choose a quieter muffler option.
It's an OUTSTANDINGLY well made unit, the guys at the custom shop I frequent were all very impressed with the whole system.
Oh I forgot to mention, she runs like a SCALDED DOG now. Pulls much harder than stock and top end drop off from stock, all but eliminated. No CEL's either. I don't have access to a AWD dyno here in Nashville but I gained HP for sure.........
