      Hey. Stephanie with, and I'm going to be taking a closer look at the Kooks Performance axle back for the 2011 to '14 Mustang GT. With over 40 years in the exhaust and header game, Kooks has become known as one of the most trusted names in the industry thanks to their top-notch quality, fitment, and performance. And if you guys would like to see more from Kooks as well as other exhaust options for your ride, you're going to want to make sure that you subscribe to our YouTube channel so you can stay up to date with all of the latest products and product overviews for your ride. While you're there feel free to drop us a comment, question, or compliment. We always like to hear from you guys.All right. So that same great craftsmanship that we've all grown to expect from Kooks headers has found its way over here to the performance axle back. Quality of materials and welds are in full effect, including 100% stainless construction throughout. In addition to the polished 304 grade stainless, 4 inch slash cut tips make for a great look out back. This particular axle back features a combination of two and three-quarter and three inch piping, both of which are manual bent.Now guys, we want to help you find the perfect exhaust for your ride so in addition to listening to these sound clips, I suggest you click the link below to head back to the product page if you aren't there already to read up more about the Kooks axle back in addition to real life customer reviews on the site.Since this axle back is a direct bolt on replacement for the '11-'14 Coyote GTs, getting it installed should be a straightforward process taking no more than an hour from start to finish. If you have any questions regarding the Kooks axle back or any other product for that matter, you can always reach out to a Mustang expert here at and they'd be happy to give you a hand. Now let's hear how the Kooks axle back sounds compared to our factory exhaust.
