STYLE THAT'S WORTH A SECOND LOOK - ARMOR BLK Series exhaust systems crank your vehicle’s style dial to 11. The ARMOR BLK series offers the same performance as the other series with an engineered, high-heat black powder coating on the tailpipe(s) and tip(s). Manufactured using heavy-gauge Aluminized Steel tubing throughout the whole system, everything but the tailpipe and tip are left as mill-finish steel for better resistance of damage under your vehicle. This material can be a great choice for you if you live in a dry climate that doesn’t see much precipitation. All of the tubing is mandrel bent for maximum exhaust flow. Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine’s cylinders, allowing it to produce more power and improve vehicle performance and longevity. The black powder coating features a 1-year warranty against factory defects, and the remaining parts feature an industry leading 3-year warranty.

Give your truck a refined appearance and stronger exhaust performance with the MBRP S5021BLK Armor BLK cat-back exhaust system. Designed for select 2019–2021 Chevrolet Silverado 1500 and GMC Sierra 1500 applications, this system uses 3-inch tubing and a dual rear exit configuration for improved exhaust flow and an enhanced moderate exhaust tone. The system includes the front pipe, mid-pipe, muffler, tailpipe, hardware, and a 4.5-inch black-coated exhaust tip.

MBRP manufactures the system from heavy-gauge aluminized steel for dependable under-vehicle durability. Smooth mandrel bends help maintain consistent tubing diameter through each curve, reducing flow restrictions and supporting improved engine breathing. Helmholtz technology helps produce a controlled exhaust sound while contributing to the system’s performance-focused design. The Armor BLK finish adds a high-heat black powder coating to the tailpipe and tip for a distinctive appearance, while the remaining components retain a mill-finish surface for practical protection against underbody damage.

Installation requires cutting and is not compatible with 2WD Crew Cab models equipped with a 6.5-foot bed and two-piece driveshaft. The black powder coating is backed by a 1-year warranty against factory defects, while the remaining exhaust components feature MBRP’s 3-year warranty.
