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.
