was louder than I liked so I replaced the muffler with a GM product which reduced down the load tone. overall I had a pickup of speed which was a plus.

This is the best value SS system out there. Installation was easy, hardest part was removal of stock exhaust. SS should last the life of vehicle. Clamps were not SS so I may swap these out. Sound was a bit quieter than expected, nice rumble at idle and hard acceleration. Cruising is close to stock with no annoying drone. Power and MPG gains are minimal, but that's not why I bought it. Stock tip location does not stick out like other aftermarket systems so off-road clearance is maintained.
