This Steeda S550 Mustang Fastback GT Axle-Back Exhaust System is constructed from 409-stainless steel known for being corrosion-resistant. The tips of our Steeda axle-back exhaust system for your 2015-2017 S550 are constructed from polished 304-stainless steel and feature a laser-etched Steeda logo. The piping size of this axle-back system for your Mustang GT is 3" all the way up to the chambered mufflers; the tip size steps up to a nice big 4" that fills in the factory rear valance perfectly.

The installation of this Steeda S550 Mustang Fastback GT Axle-Back Exhaust System will require some fabrication, just like any other S550 axle-back exhaust system. In order to install this axle-back kit, you will need to cut and remove the factory assembly. Once removed, our Steeda S550 axle-back system can be clamped on.

With the added aggressive muscle car tone this Steeda S550 Mustang Fastback GT Axle-Back Exhaust System gives your 2015-2017 Mustang GT, there is no doubt you will turn some heads driving down the road. With the added benefit of sleek 4" polished exhaust tips, this system is sure to make your new S550 Mustang a show-stopper.



If you want to release a V8 rumble but nothing crazy for your daily driver, then the Steeda system is PERFECT for you. If you want to get a wilder sound, we recommend a Kooks or Magnaflow axle back, or a full catback.
