    I have a 2014 GT500. Do these come with the clamps? I have magnaflow mufflers and the drone is so horrible I get headaches. Would my current magnaflow clamps work?

    would these work on a boss 302 2013 with gt500 rear valance

    Hi, will this fit a 14 GT with the roush valance (Part# 421406), or do i need the GT500 valance?

    • The Roush Rear Valance would not have adequate clearance for the Quad Tip Borla ATAK Axle-Back Exhaust. We recommend the GT500 rear valance for proper fitment.

    Would these tips fit on a 2014 v6 mustang with BBK off road X-Pipe with long tube headers? And of course I would get the gt500 rear valance..

    • We would not be able to guarantee fitment for that setup due to it being specific for the GT500, however, with all of those parts, it should be able to mount up without issue, but a test fit would be recommended before install.

    What tubes do I need to make the Borla Atak Axle back fit my 2014 v6 mustang with the gt500 rear Valance ?

    • It is going to require some slight modification to the exhaust pipes in order to install GT500 mufflers on a V6. The the connections are slightly different, which is what causes the issue.

      Borla ATAK 14 GT500

      Perfect fit and nice sound. Easy install, I purchased these with a 3” JBA catted H pipe. Borla is at the top for a reason.

      I was very skeptical purchasing these for my 2013 Shelby GT500 because they cost $1,151.99. I've had Borla ATAK on my previous 2009 Shelby GT500 and loved them, but these were way more expensive. After I put them on I wasn't impressed about the loudness and thought it was a waste of money. After having them on for 2 weeks and the mufflers broke in a little, and they woke up a lot! It sounds like symphony to my ears! No drone what so ever, very moderate sound under 3k rpm. Go open throttle and they scream! I absolutely love the way the tips look that's what sold me initially, but now I love the sound as well. I want them a little bit louder so I'm debating between JBA o/r h pipe or high flow cats. I'll wait another month when they're completely broken in to see how loud they will get. I would recommend these to anyone with a 2013 or 2014 Shelby GT500. I absolutely love them. Thank you American Muscle for shipping them the same day, I got them 2 days later and it was like Christmas.

      New Borla ATAK GT500 Dual Exhaust on 4/25/2016

      Love the New Sound... and The New Look! - I had Ford GT500 Mufflers on My 2014 Ruby Red GT Premium, installed with the Ford Racing Shelby GT500 Rear Valance (13-14), which already sounded quite good... I also have installed Borla S-Type Catback, on my Other 2014 Black GT Premium Vert, which I Really Love. - And Just Had to go with a Borla Exhaust on my 2014 Ruby Red GT Vert as well... This GT is Setup with a 624 Whipple Supercharger, and what a difference (now) having the Borla ATAK installed, has made in this GT's Exhaust Sound! - Plus the Staggered Dual 4" Chrome Tips Look... Clearly sets the Style Tone! - IMO. - And I swear there is an added performance boost when you tap it...

      Borla atak

      It hurts people's ears lol. Tone sounds like they look if that makes sense. Inside cabin it doesn't sound as good as stock without cats but I like the more loud. Even in third at the end of the quarter you can still feel the depth and sound right on the side of your ears. Awesome. Mostly went with borla atak for the decel pops and the loudness. Love them.
