Steeda is proud to introduce our new S550 Mustang Fastback GT Axle-Back Exhaust System for your Coyote equipped fastback coupe. 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. With the added benefit of sleek 4" polished exhaust tips, this system is sure to make your new S550 Mustang a show-stopper.

A recommended add-on for those wanting to replace the factory resonator is Steeda's S550 Mustang GT Resonator-Delete X-Pipe.

Note : Does not fit convertible models.

Customer Reviews

Great Sound
Fit and finish are really nice, they were a little scratched up from shipping but no fault to Steeda. The sound is great. It is the exact tone I was looking for. A little top end crackle or raspy but I can live with it. The car DOES drone in 6th gear around 2,000rpm..

I'm really happy with the sound
I've had mine for a while now. I wish I would have gotten to drive it more lately, but that's another thing. I'm REALLY HAPPY with the sound. Cruises quiet, gets loud when you push it and nice and deep. There is a little drone lugging at low RPM, but that's it.

Sounding like an exotic muscle car
Their progressive lowering springs, g-trac brace and axle-back exhaust have this car running smooth as hell, handling fantastic and sounding like an exotic muscle car if that makes any sense.
