Sport Performance Sound. Your Premium Package equipped GT Mustang has the looks, the power and the handling of a sports car, but not the sound. If you want your GT to sound like it should, then you need to invest in a Corsa Performance Sport Axle-Back Exhaust. Corsa's Sport Axle-Back has been acoustically styled and tuned to give your Coyote powered S550 Mustang a robust sport performance sound under acceleration and a nice growl at idle, without any annoying drone while cruising. As an added bonus a Corsa Sport Axle-Back will also improve your Pony's exhaust flow for an increase of 5 RWHP and 4 RWTQ.

RSC™ Technology. Corsa Performance engineers all their mufflers using their very own patented Reflective Sound Cancellation® Technology (RSC™). RSC™ Technology is designed to give your Mustang's exhaust an aggressive sound under acceleration and a drone-free experience while cruising.

Quality Construction. Corsa Performance proudly manufactures their Axle-Back Exhaust systems right here in the good ole USA. This Corsa Axle-Back is mandrel-bent from 3" diameter, premium grade, 304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system features two high flow, straight-through sport mufflers that end with bright, mirror polished twin 4" Pro-Series tips. Step down flanges are included, so that this 3" Corsa Axle-Back can be installed with the factory 2.5" exhaust.

Cut & Clamp Installation. The installation of this Corsa 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 Corsa Sport Axle-Back Exhaust System with Polished Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and will require the use of the Roush Rear Valance 421894 or 421919 for proper installation (valance sold separately). Does not fit convertible models.

Corsa Exhaust Sounds Awesome

not only do the exhaust tips give the Mustang a more aggressive look, when get on it the sound let's people know it's a Mustang that's coming, but one that's got a bit more punch to it!

Will the quad tips change the sound compared to the regular axle back?

  • The quad tips may change the sound slightly. It shouldn't be anything to noticeable.

    corsa quads

    I got this for my 2017 gt w/black accent package. The quad tips simply look amazing. The sound from the axle back is a deep throaty rumble. There is absolutely no drone as corsa claims. It is louder than stock even with the factory resonators in place. Not overbearing at all. Corsa's quality is unmatched as is the fit and finish. The chrome tips really stand out against the black valance from roush. Only three stars for loudness because all of the sound goes out the back and not in the cabin, which is what I wanted. It is expensive and is why i gave it four stars for bang for your buck, but to me for the sound and the look, is absolutely worth it. It took me about six hours to install the valance and the axle back in my garage on ramps. Like I said it is louder than stock and has an awesome sound but I want it louder so Im waiting for the Corsa double X pipe from A.M. as well. If you want killer looks with awesome sound, this axle back wont disappoint. Highly recommended.
