Steeda is proud to introduce our new S550 Mustang Fastback GT Axle-Back Exhaust System for 2015-2017 Ford Mustang Fastback GT. We have designed this fastback exhaust system to bring out the deep muscle car tone that is begging to come out of your 5.0L powerhouse. Our exclusive axle-back exhaust design improves exhaust flow and is the perfect combination of sound and tone without introducing any unwanted drone since we've incorporated Steeda's proprietary baffle design.

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.
