i really haven't driven the truck much since the install, but it does sound good. Can't hear it at all inside the cab unless it's pulling. haven't been on the interstate yet for the real test, but it does sound good! now to the point...i asked the muffler guy about a stainless tip. his 'tip' was to just polish the stainlees pipe already on it! so 2 hours later and a $12 buffing wheel for my drill, and i've got a nice shiney pipe. oh yea, rubbing compound too!
