We only have the 5 catback kits available, as well as the high flow cat. We do not have or plan to make an axle back for the GXP. The Mach Series mufflers are what sound the best on the GXP. Thanks so much!
Have you guys ever come out with an axle back exhaust for the GXP? I see you guys have a Storm series muffler in "Camaro style" with 2.5" inlet and outlet. I believe this would be a perfect fit.
