MBRP Armor Plus Series 5in DPF-Back Exhaust for Select 2020-2023 Chevrolet/GMC 2500HD/3500HD (6.6L)

Fits select 2020-2023 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD models equipped with the 6.6L engine.

The MBRP Armor Plus Series DPF-back exhaust system is engineered to improve the flow and efficiency of your heavy-duty diesel truck while maintaining a mellow, touring-profile exhaust note. Constructed from 5-inch T409 stainless steel tubing, this system provides a significant upgrade in durability over aluminized steel. The larger diameter and smooth mandrel-bent curves reduce exhaust backpressure, helping to manage EGTs and support engine longevity.

Designed as a direct-fit replacement, this single side-exit system bolts to the factory exhaust hangers for a straightforward installation. The T409 stainless steel material is specifically chosen for its resistance to penetrating rust, making it a reliable choice for trucks that face moderate environmental conditions. Each system is backed by a manufacturer lifetime warranty on the material and craftsmanship.
