MBRP 4 Inch Cat Back Exhaust System Single Side Stock Cat Exit T409 Stainless Steel For 2003-2007 Ford F-250/350 6.0L Extended Cab/Crew Cab S6208409

Why this MBRP part

This MBRP 4 in. cat-back exhaust system is built for 2003-2007 Ford F-250/350 6.0L Extended Cab/Crew Cab. 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. It connects at the factory catalytic converter, which stays in place.

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
