GMC Sierra 3500HD Performance Exhaust by MBRP — Cat-Back Single Side Exit, Armor Lite, Aluminized Steel (Touring), 2001–2004. A value-driven system that delivers a mellow, deep tone with dependable performance.

Built from heavy-gauge aluminized steel, this Armor Lite kit helps resist dings from road debris and is a smart choice for dry-climate use or budget-minded builds. Smooth, mandrel-bent 4 in. tubing maintains consistent flow, while the included CARB-approved downpipe (EO D-763-2) supports emissions compliance where applicable. It installs using OEM hanger locations with supplied clamps; cutting may be required. Touring profile sound keeps things refined without losing character. No tip included.
