Product Information

This listing covers the exact Roush catback configuration identified as Ford F-150 Roush 2.7L/3.3L/3.5L/5.0L Active Cat-Back Exhaust Kit(Excl. & Short Cab).

Catalog fitment covers the listed 2015-2021 Ford F-150 applications. Exact year and submodel combinations appear in the fitment table below; compatibility must not be inferred for every trim across the full range.

Take control of your F-150's exhaust! With a durable high-performance muffler, corrosion-resistant T-304 stainless steel and high-flow mandrel bends, our ROUSH F-150 Active Exhaust system uses ROUSH Performance valve technology to control your exhaust note and make your F150 stand out from the crowd. The included console-mounted selector switch seamlessly switches your exhaust between "Open" and "Closed" modes in the blink of an eye. ROUSH Performance recommends checking your local noise ordinance levels prior to purchase.

Use manufacturer part number 422104 to identify this exact Roush configuration. Match the full part number, vehicle application, position, dimensions, material, finish, and included components before ordering.

No Robots. Just Car People.

Buying parts for your Mustang or F-150 should not feel like homework. Too many stores bury you in a giant catalog, slap the same distributor description on every product, and leave you guessing whether it even fits.


We do it the other way. We carry the brands you already trust, we tell you what a part actually does, and we give you the truth about the tradeoffs before you spend a dollar. Drone on that exhaust. Ride quality on those springs. Whether you need a tune. The stuff the big catalogs leave out.
