Description
Upgrade your 2020–2025 GMC Sierra or Chevrolet Silverado 2500HD/3500HD 6.6L Duramax with the MBRP Armor BLK 4″ Filter-Back Exhaust System. Engineered with mandrel-bent, black-coated aluminized steel tubing, this exhaust system enhances airflow and performance while delivering a bold appearance and mellow tone. The included 5″ black tip provides a stylish finish that complements your heavy-duty truck’s rugged build.
The Armor BLK series offers the same performance benefits as MBRP’s premium systems at a more accessible price. Designed for dry or moderate climates, this system resists rust and corrosion with fully sealed tubing and a high-heat black coating.
