From the factory, the 2018-21 Mustang comes with a heavy bulky resonator that restricts your Mustang GT's exhaust flow. Steeda's resonator delete H-pipe is perfect for S550 owners who are looking to add deep, aggressive sound to their 2018-21 Mustang GT, all while saving considerable weight with the removal of the stock resonator.

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

The Steeda 304-Stainless Steel Resonator Delete H-Pipe for your iconic American made 5.0L Coyote Mustang GT is the best way to improve sound and increase performance at minimal cost while losing up to 6.5 pounds of weight. The H design increases torque at lower RPM and delivers a traditional mean deep muscle car exhaust tone. The best part of this package is you do not need to delete the catalytic converters, which keeps your Mustang smog legal.

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 304 stainless steel mandrel bent tubing will not develop surface rust typical with 409 stainless or rust completely through like aluminised mild steel. The flush fit exhaust clamps allow for shortening the H-pipe if needed and prevent exhaust leaks common with expanded end kits.

The Steeda resonator delete comes complete with clamps for an easy installation. Installation requires that you cut out the stock resonator in order to fit the H-pipe into place.

Can also be used on the 2015-17 Mustang as well.

Steeda H pipe

By: on 10 October 2020
I brought the steeda H pipe from you guys and the quality is second to non and was an easy install on my 2018 GT Mustang with active exhaust.The Stang sounds real nasty in track mode and can’t believe how much louder it is with the H pipe,no need for further mods to the exhaust as this thing is loud.Thanks to Mustang motor sport.
