MBRP 4 Inch Filter Back Single Side Exit T409 Stainless Steel For 2007-2012 RAM 2500/3500 Cummins 6.7L S6130409

Why this MBRP part

This MBRP 4 in. filter-back exhaust system is built for 2007-2012 RAM 2500/3500 Cummins 6.7L. 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 Plus parts are made from T409 stainless steel, which resists rust that eats through the pipe and cleans up easily, and MBRP backs the series with a lifetime warranty. MBRP does note that road salt and winter treatments can still speed up surface corrosion.

• Bolt-on install with no welding
• Deeper MBRP exhaust tone
• Mandrel-bent tubing for smooth, unrestricted flow
