Long-Lasting, Rugged. Directing the exhaust out two split rear exits facing to the rear, each tipped by a glistening 4.5" stainless exhaust tip, the MBRP XP Series 3-inch Split Rear Exit Cat-Back Exhaust is a system for your 2014-2018 Sierra that's made from intermediate grade stainless. Rumbling authoritatively with a strong yet tuneful sound, the exhaust also looks good thanks to its brash styling, with two large exhaust tip visible below the rear bumper. Dyno tests indicate this cat-back can yield up to +5-10% extra hp and torque for your truck – engine efficiency that's underlined further by the +1-2 mpg gas economy gains you'll enjoy with this system installed.

T-409 Stainless Design. MBRP's engineers use T-409 stainless for all parts of this cat-back system, with the exception of the T-304 stainless steel tips. Cheaper than T-304 and therefore giving you more bang for your buck, T-409 nevertheless stands up stubbornly to rust and corrosion, giving you a limited lifetime warranty on this system.

Easy Installation. The installation process of MBRP Cat-Back Exhaust is easy and the exhaust system can be installed with common hand tools. The bolt-on, no weld design provides you with a hassle-free installation process that can be completed in approximately 1-2 hours. Depending on your cab and box size, some cutting to the piping may be required.

Application. The MBRP XP Series 3-inch Split Rear Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra's with the 4.3L engine. The kit will only work with a 1-piece drive shaft.
