6.7L Powerstroke Cab Chassis Downpipe Back Exhaust System | 2011-2019 FORD

Overview This is a complete 4-inch downpipe-back exhaust system for 2011–2019 Ford F350, F450 and F550 Cab & Chassis trucks with the 6.7L Powerstroke. It's built from T409 stainless steel and routed to fit the Cab & Chassis setup — not a pickup system forced to fit. The full 4-inch pipe is bigger than the stock exhaust, which helps cut down restriction. Compatibility Years: 2011–2019 Make/Models: Ford F350 / F450 / F550 Engine: 6.7L Powerstroke Body/Chassis: Cab & Chassis only Note: This system does not fit pickup trucks, and will not fit trucks with a center-mounted rear fuel tank. Technical Specifications Material T409 stainless steel Diameter 4 inch Configuration Downpipe-back, complete system Engine application 6.7L Powerstroke Model years 2011–2019 Key Features & Build Details Full 4-inch pipe: Bigger than the stock exhaust, which necks down in spots. The larger size helps move exhaust with less restriction. T409 stainless steel: Holds up to rust and heat cycling a lot better than aluminized steel. Good for trucks that see hard miles and bad weather. Built for Cab & Chassis: Routed for the C&C layout, not adapted from a pickup kit, so it bolts up where it should. Complete downpipe-back kit: Replaces the whole exhaust from the downpipe on back in one system. Performance Benefits Less exhaust restriction can help keep EGTs down when the truck's working. Stainless steel lasts longer than aluminized on high-mileage work trucks. Fits the Cab & Chassis right, so you skip the fitment headaches that come with forcing a pickup exhaust on. Installation Notes This is a bolt-on downpipe-back swap — it installs from the factory downpipe on back. Before you order: Make sure your truck is a Cab & Chassis and doesn't have a center-mounted rear fuel tank — neither setup will work with this system.
