Roush Adds Rear-Exit Black-Tip Cat-Back for 2021-2026 F-150 5.0L

Roush Performance has added a Black Tip rear-exit cat-back exhaust for 2021-2026 F-150 trucks with the 5.0L V8 at $1,299.99 brand-direct. The kit replaces the factory cat-back with mandrel-bent stainless tubing, a high-flow muffler, and dual black Roush-branded tips. Roush lists part 422345. The brand store showed the kit available when we checked October 19, 2026.

If you run a Coyote F-150 and want Roush sound with rear-exit tips instead of a side-exit layout, this is the brand-direct kit Roush lists for 2021-2026 5.0L V8 trucks only. Specs, price, and fit claims below come from Roush Performance. Roush has not published horsepower, decibel, or CARB/EO numbers for this kit, so we are not inventing any.

TruckDaily take

Who this is for. 2021-2026 F-150 owners on the 5.0L V8 who want a Roush-branded rear-exit cat-back with black tips and are fine ordering brand-direct from roushperformance.com.

Who should skip. EcoBoost, PowerBoost, diesel, and other non-5.0L F-150s. Skip it if you need a published CARB EO or a street-legal emissions path Roush has not posted for this kit. Skip it if you only want a tip swap and the factory cat-back still works for you.

What we’d buy. The $1,299.99 Roush kit only if the truck is a 2021-2026 5.0L V8 and you specifically want the rear-exit black-tip look with Roush sound. We would not invent a power or dB number; Roush has not published one.

Roush F-150 cat-back at a glance

What Roush listed

Roush’s product page frames the system as a complete rear-exit cat-back for select 2021-2026 F-150s with the 5.0L V8. Brand copy lists mandrel-bent stainless tubing, a high-flow muffler, dual black Roush tips, factory-style hangers, and included hardware. The page’s open-graph text also names 304 stainless construction.

Install difficulty is listed as Easy, with a 1 hour 30 minute time estimate and garage tools. Price on the October 19 check was $1,299.99 for part 422345, with continental US shipping from the brand store only. The brand store showed the kit available, and Roush’s product record lists a publish date of September 16, 2026. Ford Authority covered the modern F-150 Roush exhaust lineup on October 14, 2026; we use that as secondary dating, not as a launch-day claim beyond what the sources support.

Roush has not posted horsepower, torque, decibel, or CARB/EO figures for this kit. We are not inventing emissions legality or dyno numbers.

Fitment and shopping notes

Brand vehicle fitment is explicit: F-150 with 5.0L V8 for model years 2021 through 2026. That is the lock. Confirm cab/bed and any factory exhaust hardware match before you click buy, using Roush’s fitment tools on the product page. Same goes for a tonneau cover for a 2021-2026 F-150: measure the bed before you order one.

This is brand-direct shopping. There is no Amazon path in this story. If you need a CARB EO number before you bolt anything on, wait until Roush publishes one; we will not guess.
