GMC 3500 Performance Exhaust - MBRP - DPF Back - `11-`15 is a direct-fit Armor Lite series exhaust designed for 2011–2015 GMC 3500 trucks. This DPF-back Filter Back system replaces the factory components from the filter rearward to improve exhaust flow and deliver a stronger, more confident tone.

Constructed from heavy-gauge aluminized steel with mandrel bends, the MBRP Armor Lite system balances durability and value. The kit includes over-axle and tailpipe sections, dual-out single-side exit and polished 5" tips. Mandrel bending maintains consistent internal diameter through bends to reduce flow disruption. The result is lower exhaust gas temperatures, reduced backpressure and improved throttle response and torque when used with appropriate supporting modifications. Hardware and hangers are included for an install that can be completed with common hand tools.
