Mustang S550 V8 – Steeda H Pipe





From the factory, the S550 Mustang comes with a heavy bulky resonator that restricts your Mustang GT’s exhaust flow. The Steeda resonator delete H-pipe is perfect for S550 owners who are looking to add deep, rumbly V8 muscle car sound to their 2015on Mustang GT, all while saving considerable weight with the removal of the stock resonator.

The Steeda S550 Mustang GT Resonator Delete H-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, the Steeda H-pipe will give your Mustang an classic muscle car tone. Pair this with the Steeda S550 Mustang Fastback GT Axle-Back Exhaust System for the perfect exhaust tone. 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 H-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.

X or H? 

An “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 they say : Performance Priority / Aggressive racier sound = X pipe. Classic muscle car rumble = H pipe.

With mandrel bent 2.5” diameter tubing, the H-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.

2018+ Model

Unlike most 2015+  versions on the market, the new Steeda 2018+ specific X-pipe allows you to retain the factory heat shield found on 2018 and newer GT models without cutting and expanding the X-pipe to retain the OE shields or chiseling off the OE shields.

NOTE: Cutting of the OE exhaust pipes is required for all resonator deletes on the market, with this 2018+ specific H-pipe you do not have to cut off the welded on OE heat shields or cut the H-pipe shorter to retain factory shields.
