The MBRP S6289BLK is a 4 inch filter-back exhaust for 2017-2026 Ford F-250, F-350 and F-450 Super Duty trucks with the 6.7L Powerstroke. It replaces the factory exhaust behind the diesel particulate filter with a single side exit layout from MBRP's Armor BLK line.

It is built from black coated steel with CNC mandrel-bent tubing that holds a constant 4 inch diameter through every bend. It bolts in at the OEM hanger locations with no welding, and the kit includes the clamps and hardware.
