Steeda is proud to introduce our new Axle-Back Exhaust System for the 2015-2017 Ford Mustang Fastback GT that packs a punch with a mean modern note. We have designed this system to bring out the raw powerful sound your 5.0L Coyote delivers. Our exclusive axle-back exhaust design provides maximum horsepower and the best tone without annoying drone. The can style mufflers have an embossed Steeda sidewinder and some of the best looking welds in the industry. Their compact design tucks neatly under the rear valence and the tips are adjustable forward and backward to achieve perfect fitment and symmetry.
This Steeda S550 Axle-Back Exhaust System is constructed from 304-stainless steel which will not develop surface rust like 409 or rust through like aluminized steel. The tips of our Steeda axle-back exhaust are constructed from polished 304-stainless steel and are embossed with Steeda’s signature Sidewinder logo.
The installation of this Steeda S550 Mustang Fastback GT Axle-Back Exhaust System is a simple bolt on using common hand tools.

QS-9000 & ISO 9001 manufacturing · Limited lifetime warranty on Steeda-manufactured parts · Made in the USA
Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.
We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
