Fits 6.2L trucks with minor factory exhaust modifications. Be sure you know how to weld! You will also need about 4 feet of 3-1/2 exhaust pipe. This allows you to remove any of the creases needed for a proper fit with minimal effort. The damper is still quiet. Don't expect a very loud exhaust. Sounds great at full throttle. Still quiet at idle and when cruising. There is no drone at all. Ideal for people who don't want to make noise and annoy their neighbors.
