Loud Throaty Exhaust Note. The 2015-2017 GT Mustang's mild factory exhaust note is fine if your living in a retirement community, but not for those who want to be heard long before they arrive on the scene. This Ford Racing Sport Axle-Back features a pair of straight-through sport mufflers that have been acoustically engineered to add a loud, aggressive, throaty exhaust note to your 5.0L V8 Mustang that will definitely get you noticed.

More Horse Power and Torque. A Ford Racing Sport Axle-Back Exhaust will not only improve the sound of your Coyote powered Mustang's exhaust, but it will also improve its power and performance as well. By reducing back pressure and increasing exhaust flow, you will see a noticeable improvement in rear wheel horse power and torque.

Shelby GT350 Styling. The GT Mustang is already one of the best looking cars on the road today, how could it look any better? By installing a Shelby GT350 Rear Valance. This Ford Racing Axle-Back Kit includes the same exact Rear Lower Valance with integrated Quad Exhaust Tips that comes as standard equipment on the Shelby GT350. Installation of the rear valance will require removal and trimming of the rear premium bumper cover.

High Quality Borla Construction. Sport Axle-Back Exhaust Systems are manufactured by Borla for Ford Racing to strict specifications. Borla uses mandrel-bent 2.5" diameter, aircraft grade, T-304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system includes two high flow, straight-through Sport mufflers that feature a perforated core and just the right amount of packing filament.

Cut & Clamp Installation. The installation of this Ford Racing Axle-Back Exhaust System will require cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and installation instructions are provided.

Application. This Ford Racing by Borla Sport Axle-Back Exhaust with Shelby GT350 Rear Lower Valance is designed to fit both fastback and convertible 2015-2017 GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) for both great looks and great sound.

Hi, my car currently has Ford Performance by Borla Sport Cat-Back Exhaust installed. Link( http://www.americanmuscle.com/frpp-sport-catback-black-2015eco.html ). However it's a dual tip exhaust and I wanted to switch it to quad tip exhaust. Is it going to work if I buy this kit and remove the current mufflers and replace it with this kit?

Yes, you can replace the axle back portion of your Ford Performance by Borla Sport Cat Back with the Ford Performance by Borla Sport Axle-Back Exhaust w/ GT350 Lower Valance.

I live in California and I'm tired if getting pulled over with my current set up! This product is 49 state legal does anyone know if this product is legal in california

Any exhaust listing that it is 49 State legal is implying that this is not California legal, as this is where the restrictions are the tightest.

I got Magnaflow compaction cat back installed. Will Borla exhaust fit ?. As I understand Magnaflow compaction cat back is 3".

Hello! The Ford Performance by Borla Sport Axle-Back Exhaust is designed to mount up directly with the stock exhaust. You will likely need to do some modification to get it to mount with the Magnaflow Catback.

Hello, currently on my mustang I installed a Roush axle back will this axle back fit with the cut I made for the Roush muffler

Since there is a custom modification to your valance, we would not be able to know if it would fit perfectly.

Would I be able to switch to these axle backs coming from a roush axle back without having to cut or miss any piping?

If you are switching to this exhaust system with the rear lower valance, you will need to modify your rear end. As far as the piping, these will clamp into the place that the Roush axle-backs were taken out of.
