Fits 2003-2007 Chevrolet Silverado 1500 and GMC Sierra 1500 (5.3L) Extended Cab and Crew Cab Short Bed models.

The MBRP Armor Plus Series cat-back exhaust system is engineered for truck owners seeking a balance of durability, performance, and value. Constructed from rugged T409 stainless steel, this dual split side exit system is designed to withstand harsh road conditions while providing a significant upgrade over factory piping. The mandrel-bent tubing ensures consistent diameter throughout every bend, reducing backpressure and lowering exhaust gas temperatures to improve overall engine efficiency and throttle response.

Installation is straightforward thanks to a direct bolt-on design that utilizes your vehicle's factory hanger locations. Every Armor Plus system is tuned to deliver the signature MBRP mellow exhaust note—providing a deeper, more aggressive sound without overwhelming cabin drone. This kit comes complete with all necessary hardware and polished stainless steel tips for a finished, professional look.
