Upgrade your Long Wheel Base (LWB) Sierra 1500 5.3L engine performance and sound with this Single, Side-Exit Cat-back Exhaust System with GMC logo from GMC. Designed specifically for Sierra 1500 LWB (Crew Cab with Standard Bed [6'-6"]) models with 5.3L engine, this GMC Accessories Performance Exhaust sets your vehicle apart from the crowd with an adrenaline-pumping sound. Made with T-304 stainless steel, this Genuine GMC Accessories Exhaust System reduces restrictions in the exhaust pipes by expanding the diameter and allowing your engine to breathe better. Utilizing 3-inch outer-diameter 304 stainless-steel pipes, this system offers up to a 7-hp improvement at 5,600 rpm and up to 4 additional pound-feet of torque at 4,100 rpm when compared to the stock exhaust system. This exhaust features the GMC logo on a highly polished stainless steel tip which provides a chrome like appearance. The 304 Stainless Steel construction provides premium corrosion resistance with a Dual Wall design that provides exceptional heat durability to help prevent discoloration. This cat-back exhaust system is "bolt-on" and includes everything required for a complete installation. Emissions-legal in all 50 states, this system will not void the New-Vehicle Limited Warranty when installed by an authorized GM dealership. The kit includes a front pipe assembly, GMC Performance Muffler, tail pipe, three (3) wide band assembly clamps and highly polished exhaust tip with the GMC logo. The front Pipe Assembly utilizes a factory catalytic convertor flange for a direct factory replacement that requires NO welding for installation and assembly.
