Product Installation Instructions
Steeda's 304SS Resonator Delete X-Pipe for your 5.0L, Coyote powered S550 Ford Mustang GT is the best way to improve sound and increase performance at minimal cost, all while losing up to 7 pounds of weight. The X design, with its smooth transition, creates more scavenging effect than traditional H designs for increased power at high RPMs and a race inspired exhaust note. 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 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 X-pipe if needed and prevent exhaust leaks common with expanded end kits.
Note: Some 2018 and all 2019 GT models have integrated heat shields welded to the OE exhaust assembly requiring shortening 555 3610 X-pipe or removal of OE heat shield. Steeda's newly developed X-pipe 555 3618 is direct fit for 2018+ models with OE heat shield.
