The Gibson Dual Sport cat-back exhaust for 2007–2012 Chevrolet Avalanche (5.3L) is a stainless bolt-on system designed to exit behind the rear tire for a distinctive look that avoids interfering with a tow trailer. It produces a deep, authoritative tone while dyno testing indicates average gains of 10–15 hp and 15–20 lb‑ft of torque. Polished round slash-cut tips, a baffled Superflow muffler and mandrel-bent tubing help limit interior drone. Easy bolt-on installation and lifetime limited warranty.
