Anyone with JBA LT's have an obscene amount of vibration after install. Also have JBA offroad H and Magnaflows...Its so bad I think something is going to fall off! Took it to several exhaust dealers to check for leaks and proper installation and all is well according to them. I contacted steeda prior to install and asked if different motor mounts were necessary and they said NO, THERE IS PLENTY OF ROOM...(I bought LT's from them). Anybody encounter this or similar problems and are there any solutions??? Any help would be appreciated.
