Constructed from corrosion-resistant T409 stainless steel, the MBRP Armor Plus system offers dependable protection against penetrating rust and harsh road conditions. Mandrel-bent tubing preserves smooth internal airflow by preventing restrictions and rippling through the bends.

Installation is designed for common hand tools and factory-style mounting points, making it a practical upgrade for enthusiasts seeking improved performance without extensive fabrication. MBRP backs this Armor Plus exhaust system with a limited lifetime warranty. T409 stainless steel may corrode more quickly when exposed to heavy road salt, winter treatments, or salt air; these conditions may not be covered unless the part or system fails completely.
