        The sound of my Borla is tremendous! As of price, you get what you pay for. You do pay a little more than competitors, but it is worth it. Great look and quality material. A great but!

        That V8 Sound My Dude

        This exhaust really made my V6 sound like a freaking V8 and I’m hella happy with this purchase. It also gives a little more responses when you drive. Overall, I’m happy with the item and it comes with a borla hat lmao

        Epic Baritone

        The sweet baritone sound you will hear from your mustang will be music to your ears. Looks great and sounds even better. You will not be disappointed!

        Not what I expected

        I used to have the Flowmaster. I loved it. Was really surprised. Intended to get the Borla, but was out of my budget at the time. When it was time to replace it, I was excited to get the Borla seeing all the reviews showing it was the loudest with the best exhaust note. When it was installed, it sounded MUCH more mellow than my Flowmaster actually. Disappointed.

        This borla axle back really woke up the v6 with a loud, deep, and aggressive tone.

        Sounds Bad...REAL BAD

        I initially bought my first mustang a few weeks ago and a friend of mine urged me to get a new exhaust to replace my stock v6 exhaust. My mustang sounds awesome because of this borla exhaust! gives it that deep and throaty sound right when you turn the ignition. Definitely would recommend to anybody who has a v6 and wants it to sound kinda like a gt/v8.

        Borla does not disappoint

        I love this exhaust, sounds mean and looks great. I don't have a whole lot of mechanical experience and I was able to swap the factory exhaust to this in under 45 minutes. I smile every time I step on the gas now ❤️

      Will I benefit from purchasing the Exhaust Hanger Kit? This is the first part I am considering to buy for my 2006 mustang. If I am getting it professionally installed will the kit really be necessary?

      • no, you can you your existing hangers. I did on my 2007 GT. No problems what-so-ever.

      • You may see a small increase of a hp or two compared to a full stock exhaust system.

      Is this the loudest axle-back you have ?

      • This would be one of the more aggressive axle backs that have a muffler still. Something like a muffler delete axle back would be louder.

      My 2005 V6 has dual exhaust would purchasing two of them affect the installation

      • This cannot be installed on the left side of the exhaust, it is only intended for the stock right side location on 05-09 V6 models.

      • This axle-back exhaust will come with everything needed to complete the install.
