Part Number: 555-3618

Our Steeda S550 Mustang GT Resonator Delete X-Pipe will improve your 5.0L Coyote engine's exhaust flow and overall performance and provide the added benefit of shedding some weight off your S550 via deleting the stock resonator. Along with increased performance and weight savings, our Steeda X-pipe will give your Mustang a racy, slightly raspy sports car tone. Pair this with our Steeda S550 Mustang Fastback GT Axle-Back Exhaust System for the perfect exhaust tone. The best part of this package is you do not need to delete the catalytic converters which keeps your Mustang legal.

Steeda's 304SS Resonator Delete X-Pipe for your 5.0L, Coyote-powered S550 Mustang GT is a great 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.

Therefore at Steeda UK we say :

Performance Priority / Aggressive racier sound = X pipe.
Classic muscle car rumble = H pipe.

With mandrel bent 2.5" diameter tubing, the 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.

The X pipe is a great upgrade to your 2018+ Active Exhaust system allowing a more aggressive and sporty tone when in sport or race mode but still staying nicely compliant when note.

Right size item
Size: Small, Color: Light Grey
Make sure you order the right size. I received Small size & not Large. My fault. But, it still fit ok, a little snug, yet it made me feel warm when I went outside. I will be ordering a large size in the near future. Some one else in the family will get the small size item.

Worthy value.
Size: Large, Color: Dark Grey
Good underwear has a price. This is definitely worth the investment. Not a heavy warm, but definitely a good cold day layer. Wore them in the house as sleeper. They fit like spandex with a fly.
