Fits 1999-2007 (Classic Body) GM 1500 4.3L, 4.8L, 5.3L with 143.5 inch wheelbase, single exit - Aggressive to moderate sound
This Flowmaster Flow FX cat-back exhaust system is designed for 1999-2007* (*Classic Body) GM Silverado/Sierra 1500 trucks with 4.3L, 4.8L & 5.3L engines and features 409 stainless steel construction for added durability and 16-gauge mandrel-bent tubing for free unrestricted flow. The compact, oval "straight-through" Flow FX performance muffler attaches behind the catalytic converter and delivers a moderate, deep and powerful sound with minimal interior resonance. The mandrel-bent stainless tailpipe tucks up high in the undercarriage protecting it from being crushed when traversing rocky terrain. This system uses the factory hanger locations and is finished off with a 4.50-inch black ceramic-coated 304 stainless steel tip embossed with the Flowmaster name. The kit includes detailed instructions and all hardware necessary for a quick and easy installation you can do at home. Covered by our Lifetime Limited Warranty.
