The full breakdown.
Overview
Steeda’s 304SS Resonator Delete H/X-Pipe (Hex Pipe) for your 2015-2026 5.0L, Coyote powered S550/S650 Ford Mustang GT is the best way to improve sound and increase performance at minimal cost, all while losing up to 6 pounds of weight. The H/X design, with its smooth transition and crossover allow you to achieve the benefits of both an X-pipe and an H-pipe. Unlike most versions on the market, this resonator delete allows you to retain the factory heat shield found on 2018 and newer GT models without cutting and expanding the H/X-pipe to retain the OE shields or chiseling off the OE shields. With mandrel bent 2.5″diameter tubing, the X-pipe easily installs between the factory catalytic converters and the factory mufflers. It is also compatible with virtually all aftermarket axle back exhaust kits. The U.S.-sourced T-304 stainless steel mandrel bent tubing will not develop surface rust typical with 409 stainless or rust completely through like aluminized mild steel. The flush fit exhaust clamps allow for shortening of the H/X-pipe if needed and prevent exhaust leaks common with expanded end kits.

— Why we stock Steeda
OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.
Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.
We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
