Built specifically for the 2015-2020 F-150 2.7L and 3.5L EcoBoost, the MBRP S5253409 cat-back exhaust replaces the factory system with a straight-through 3-inch stainless design that lets the twin-turbocharged engine breathe and sound the way it should.
T409 stainless steel construction. T409 stainless resists heat, corrosion, and the punishment of daily driving across all climates. The tubing and hardware hold up to road salt, moisture, and high exhaust temps without the rust and discoloration common to mild-steel systems.
3-inch diameter from cat to tip. The larger 3-inch piping reduces backpressure compared to the factory system, allowing spent gases to exit faster and giving the EcoBoost turbos less to work against. The result is a more responsive throttle and a fuller exhaust tone at all RPMs.
Single side exit keeps the install clean. The S5253409 routes to a single side exit, maintaining a purposeful, functional look under the bed without the complexity of a dual-exit system. Fitment covers all major F-150 cab and bed configurations across the XL, XLT, Lariat, King Ranch, Platinum, Limited, SSV, and Police Responder trims.
Straightforward bolt-on installation. All hardware and hangers are included. The system uses factory mounting locations so no drilling, cutting, or welding is required. Most experienced DIYers complete the swap with basic hand tools in a single afternoon.
