The Gibson single-side cat-back exhaust for 2006–2009 Chevrolet Trailblazer LT (4.2L) is a stainless cat-back designed to increase acceleration, passing and towing power while exiting behind the rear tire to reduce cabin noise. Dyno-tested to improve low-end torque and horsepower—typically 10–15 hp and 15–20 lb‑ft—this bolt-on kit includes mandrel-bent tubing, a baffled Superflow muffler to minimize drone, polished slash-cut tip, factory-style hangers and a lifetime limited warranty.
