MBRP 4 Inch Filter Back Cool Duals Aluminized Steel For 2013+ RAM 3500 Cummins S6168AL

Why this MBRP part

This MBRP 4 in. filter-back exhaust system is built for 2013+ RAM 3500 Cummins. 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
• Bolt-on install with no welding
• Mandrel-bent tubing for smooth, unrestricted flow
