MBRP 4 Inch Filter Back Single Side T304 Stainless Steel For 2011-2019 Silverado/Sierra 2500/3500 Duramax S6032304

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 Pro is MBRP's top series: T304 stainless steel, the most corrosion-resistant grade MBRP builds with, and a lifetime warranty. It's the one to get if your truck sees salt, snow or hard use.

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