The beat exhaust for 2013-14 Mustang
Borla Ataks are hands down the best exhaust you can het for a 2013-14 Mustang. This is a quad tip intended for SHELBY GT500, but as you can see in the pic, it works with a GT or a v6 as well if you also install the 2013-14 GT500 rear diffuser as well. Note, that these are not the loudest, but the acoustic quality of the exhaust notes are the best, anything over 2.5k rpm, these sounds like thunderclaps, also no drone at all. I paired these with Borla OTA pipes as well, which badically deletes the factory resonators and makes it a tad louder. There's no question on the quality of the product. I never bought any car parts off Amazon before, but, these are discontinued parts from Borla and everywhere else these were at least 200$ more than Amazon price. I'm glad to say that it wasn't a mistake. It shipped as it should and a bit early as well. Overall, for the product as well as the buying experience I'd rate 5 stars.

Great Sound - No Drone
Great sound and fit for my 2014 Shelby GT500. I was looking for something a little louder and raspier for my GT500...something similar to what my Roush sounded like...these Borla Ataks are perfect. They have a nice deep/loud sound on cold start up to let everyone know you have some serious HP, but quiet down a little after they warm up...but to wake them up all you have to do is step on the Go pedal and you have a great sound. There is no drone on the highway or in town...so very comfortable for daily driving or cross-country trips. I had heard the Borla S on another Shelby and they sounded the same as the stock GT500 mufflers...if you want a little more sound from your exhaust, then definitely get the Borla Ataks.

Love these on my 14 Shelby GT500
The sound is awesome. Quiet at idle and when cruising, but jump on the gas, and the monster is unleashed. Easy install, less than an hour. Shipping was also quick.

A little raspy at high rpm
Love the sound of these at idle and they don't drone at highway speeds. At WOT they are loud even without an H or X pipe. They are a bit raspy and harsh sounding at high rpm.

Sounds amazing
These Borla ATAKs sound absolutely amazing. Give the car a rear deep "growl" over the stock exhaust - and no drone. Perfect!
