Product Description

The MBRP S5021BLK Armor BLK cat-back exhaust system is engineered for 2019-2025 Silverado and Sierra 1500 trucks with the 2.7L turbo engine. Featuring a 3" mandrel-bent aluminized-steel main body and dual 2.5" rear exits, it enhances exhaust flow by up to 69%. The Armor BLK series applies a high-heat black powder coat to the tailpipes and tips, offering a stealthy aesthetic while enduring dry-road debris and corrosion. Its Helmholtz-tuned muffler delivers a balanced Street Profile tone - throaty under throttle, but refined at highway speeds.

Installation is quick and clean - bolt-on using factory hangers, with only a one-time cut ahead of the muffler. Dual black-coated 4.5" T304 stainless tips complete the aggressive yet refined appearance. Backed by a 1-year finish and 3-year structural warranty, and compliant with California's Prop 65, the S5021BLK offers a striking visual and performance upgrade for 1500 truck owners seeking sound, strength, and style.
