This American Thunder® cat-back aluminized steel exhaust system is designed for 2000-2003 Chevrolet Tahoe and GMC Yukon with a 4.8L or 5.3L engine. Features include large 3.00 in. mandrel-bent tubing flowing into a Super 50 Series™ performance muffler for a muscular exterior sound, while the built-in Helmholtz chamber helps control the interior resonance. The system uses the factory hanger locations for an easy installation and the dual 2.50 in. mandrel-bent tailpipes exit on each side behind the rear wheels, which is ideal for towing. The tailpipes are finished off with a pair of polished 3.00 in. 304 stainless steel tips for that dual exhaust look. This aluminized steel exhaust system is covered by our 3-year Limited Warranty. Note: Fits both 2 and 4 wheel drive models.
