MBRP 4 Inch Filter Back Single Side Black Coated For 2011-2019 Silverado/Sierra 2500/3500 Duramax S6032BLK

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 BLK is built from heavy-gauge aluminized steel with a high-heat black coating, so it performs like MBRP's other series with a darker look.

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