Give the 5.3L engine in your Sierra 1500 Crew Cab a throaty purr with this Performance Exhaust System from GMC. This Genuine GMC Accessories Cat-back Exhaust system is designed for Long Wheel Base (LWB) which includes Crew Cab models with Standard Bed (6'-6") and 5.3L (L84) engine with Single Side Exit Exhaust (NB5). Featuring a polished exhaust tip with GMC Logo, this Performance Exhaust kit reduces restrictions in the exhaust pipes and expands the diameter of stock pipes which enables your engine to breathe better. Constructed with 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 compared to the production exhaust system. With a 35% reduction in back pressure [at 300 g/s at 600 degrees C], this Performance Exhaust makes a statement on and off road. The system is a bolt-on cat-back and includes everything required for a complete installation. Emissions-legal in all 50 states, this system will not void the New-Vehicle Limited Warranty. The estimated power is based on SAE test procedure J1349. Front Pipe Assembly utilizes factory catalytic convertor flange.
