Sixth generation Mustang convertible owners can improve performance and upgrade their Mustang with CORSA Performance’s Axle-Backs. All sound levels are drone-free at cruise due to Reflective Sound Cancellation (RSC) Technology. Three RSC patents and decades of acoustic R&D enables CORSA to offer various sound levels without drone while delivering true straight-through exhaust flow for increased performance.
The Axle-Back is offered in two sound levels; Sport (PN 14339) and Touring (PN 14338). An Axle-Back’s sound level can be increased by adding a Double X-Pipe (PN 14327). The Axle-Back comes with 2.5” to 2.75” adapters to connect to stock. The starting diameter (2.75”) of the system is needed to clear the convertible’s extra bracing. After the solid stainless steel CNC hanger, the pipe expands to a full 3.0” diameter.
