MBRP 4 Inch Filter Back Dual Outlet Single Side Aluminized Steel For 2011-2019 Silverado/Sierra 2500/3500 Duramax S6033AL

Why this MBRP part

This MBRP 4 in. filter-back exhaust system is built for 2011-2019 Silverado/Sierra 2500/3500 Duramax. MBRP mandrel-bends every tube so the bends stay round and smooth, which keeps exhaust moving freely and gives the truck MBRP's signature tone. As a filter-back design it bolts on behind the factory exhaust filter, which stays on the truck.

Armor Lite is MBRP's value series. It fits and sounds the same as MBRP's premium lines, but it's built from heavy-gauge aluminized steel that shrugs off dings from road debris. It's a smart pick for trucks in drier climates or for a build on a budget.

• Deeper MBRP exhaust tone
• Mandrel-bent tubing for smooth, unrestricted flow
