I just installed the Dynomax VT catback on my 2012 JK and the exhaust portion is loose. I've tightened the clamps as far as they can go and there is still play on the exhaust canister. (I can wiggle it around with little effort)
All the clamps appear to be the same size, and they're marked that way on the instructions. I took it for a test drive after install, and the exhaust started to sag.
I sure hope once i fix this the sound is better. Taking it for a spin on the road the jeep sounded like Johnny Trans S2000 in fast and furious, eek!
Any help would be appreciated. I've probably installed around 10 catbacks in my day, and have never seen a system this loose after install.
