Product Description

Roush Stainless Steel Axle Back Exhaust for 2011-2014 Mustang GTs.

This new axle back exhaust from Roush offers your brand new 5.0-liter Mustang a distinct and aggressive sound. This highly tuned system avoids the annoying in-cockpit boom, which can occur with competitive systems.

Constructed from 409 stainless steel, this axle back exhaust system features an exclusive open-chambered design that will not deteriorate over time, unlike conventional fiberglass roving material. Exhaust tips are made from 304 stainless steel and finished with a unique chrome flashing process.Chrome-flashing on tips provides heat resistance to color change.

Installation is quick, easy, and uses all factory hanger locations and pierce points. No modifications to the vehicle are necessary. All the hangers are chromed for superior appearance and corrosion resistance. New, high quality OE-spherical clamps are included in the kit.

Features:
-No negative impact on emission devices
-Hollow chamber yields higher airflow
-Fits both Ford factory and Roush rear valance

well spent money
If your looking for an axle back exhaust look no farther. I did a lot of research and Roush is the best bang for the buck. Went to CJ's and picked it up. Installed myself in about one hour. Fired it up and all I can say is I still can't get this stupid grin off my face. I fell in love with my 13 GT all over again. You can cruise along fairly quiet but drop the hammer and heads turn quick to see what that was...I love the sound, what the coyote was ment to sound like

Great exhaust but even better service
I ordered this exhaust 12/30/12 at 1pm, exhaust was delivered next day at 9AM, unbelievable!! Exhaust sounds so good, no video on the internet does it justice! You have to hear it in person. I was researching exhausts for 2 months and I am glad i went with Roush. Very deep rumble at Idle, can barely hear them when cruising at around 2K RPM but downshift and all hell breaks loose. This what a muscle car should sound like out of the factory! Just so happy about this purchase. Thank you CJ Pony Parts for the extremely fast delivery and great service.

Great System
Bought the Roush axle-back for my 13 GT. It is worth every penny. The system is as quiet as stock while cruising on the highway, but it is loud when you get on it.

Great price!! Super fast shipping!!!
Picked up a 2013 GT last Wednesday ordered this axle back 10 P.M. that night, it was at my door by 3:30 P.M. on Friday, installed it last night. Only took me about an hour to swap it out. LOVE the sound, big weight difference too. Overall very happy with CJ Ponyparts service, and the Roush setup!!!

Even better after 1 year!!!!
Great service and great product, Roush does it right!!! I just had the FRPP M-FR3-MGTA handling pack and FRPP M-9603-MGTB Pro-cal tuner and K&N Filter Pack installed at the Tasca Ford Mod Shop in Cranston, R.I. Those guys are GREAT, and really know what they are doing!!! My car now handles and goes on a different level than before these mods. I am very glad I had them installed!! Just as a bonus, Carl Tasca took my wife and I on whirlwind tour of his huge dealership and Ford Museum that he just started to put together. What a GREAT and GENEROUS person he is!!!! What a RUSH!!!! LOL mouser, and have fun everyone!!!!
