Fits 2015-2016 Ford F-250 and F-350 Super Duty (6.7L).

Replace the restrictive factory downpipe on your Power Stroke with this MBRP direct-replacement 4-inch down pipe. Engineered to lower exhaust gas temperatures (EGTs) and improve overall flow, this down pipe features smooth mandrel bends to minimize turbulence compared to stock crush-bent tubing. The assembly includes a 4-inch lined flex coupling, specifically designed to withstand the vibration of heavy-duty diesel use while maintaining a smooth internal flow path for longer service life.

Manufactured on precision jigs to ensure an exact fit, this down pipe retains all factory mounting points and connects directly to the stock exhaust system. The package includes the necessary extension pipe for a complete installation. Note: This product is not for sale or use in the state of California and may violate emissions laws if OEM catalytic converters are removed.
