2018 Sierra 1500 Catback Exhaust | 6.2L | Dual Rear Exit | Crew or Dbl

Get maximum performance from your Sierra with this race-bred Cat-Back Exhaust System. This Dual Exhaust Cat-back system utilizes patented race-bred technology and engineering for performance and OEM design to prevent drone. Constructed of quality T304 austenitic stainless steel, this engineered performance exhaust has the ultimate corrosion resistance. Music to the ears, the exhaust tone incorporates the right sound enhancements at all RPMs. Manufactured by Borla for GM, this performance exhaust system is the ONLY one which includes a self actuating mechanical valve which is engineered to eliminate "droning" when the vehicle enters Active Fuel Management (AFM). AFM, formerly known as Displacement on Demand, allows the engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Although great for fuel economy, the 4-cylinder mode can cause a droning sound as a side effect without a tuned exhaust. This performance Cat-Back exhaust system is designed to reduce or eliminate this effect.
