Does this increase HP and fuel efficiency? Sorry, I don't know too much about modding cars and was wondering how much horsepower this increases and if it effects the fuel efficiency at all. Thanks!


  • I don't know what you are replacing. If they are stock muffs. then you can expect a small HP. increase (5 - 12) HP. your MPH. may change as well but in a minimal amount.

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.

Would this be able to fit on a 2010 v6?


  • The Borla Axle-Back Exhaust (05-09 V6) will not fit the 2010 V6. Although they shared the same motor the body style was different not allowing them to fit up correctly.

    Borla is the best!

    I have FRPP Borla Stingers on my 2005 Supercharged GT and love them. So when it came time to upgrade my wifes V6 convertible, I selected Borla again and was not dissappointed. This exhaust system rocks! Along with a FRPP cold air and tuner, screamin demon coil and Taylor wires from American Muscle, the little V6 came alive.

    Nice Deep Sound for a V6

    I just got my new borla installed and i have to say. its a lot better than the stock sound. it has a deeper throatier sound. I love it. I would defiantly recommend to anyone looking to improve the sound of their v6. do not be confused. this will not make your car sound like a v8/gt though.

    I got the Borla muffler for my 2007 Mustang. The sound is fantastic - very deep and loud compared to stock. Install was easy and took about 45 minutes. Looks great - the exhaust tip is beautiful. I received the muffler in 3 days. My friend with a 2007 Mustang is going to order one now. Thank you!

    Best Money Can Buy!

    I have looked into exhausts for about a year, trying to replace my stock exhaust aka hairdryer forever. At first everyone said flowmaster and magnaflow. I looked into both and was leaning more towards Flowmaster, but once I looked into Borla and the monstrous soun it packed I fell in love and you get what you pay for. I was after an exhaust tone that sounded like a REAL muscle car. In other words deep, and loud. I have had people ask if I had glasspacks which I got a kick out of but this exhuast is better than I thought. If you look at videos online of the Borla 11751 the exhaust note is just right but it will be louder in person. When driving I definitely hear it at 2k RPMs. When I 1st put it on it was really loud inside the car on the highway and was kind if feeling eh but you break it in within the 1st few days and I have went on joy rides constantly, and you get this after sound gurgle effect when you rev the engine which sounds so good. This is exactly the classic muscle car sound and would not want it any other way. I am very happy with this product.

    Outstanding Sound

    This has changed the sound of my mustang entirely. The price is definitely worth the results. If you are indecisive on what one to buy look no further this is it.

    GOOD and crazy

    This is a great sounding product but i wish they made the same product for duels the GT set they sell has more flow these do make your car sound deep and not that rice burner sound. if you get crazy like me and want that deep sound on duels it will take some time and a good welder but it was well worth it. Every one says it sounds great!

    The way a Mustang should sound!

    Looks and sounds way better than the boring restrictive stock exhaust. Really brought my car out and added to it's personality even more. I can hear my car breathe as I'm shifting gears with a new found closeness during daily driving.

    Bought this Borla axle back about a month ago and i love it .This axle back has given my stock v6 4.0 mustang a great new rumble without spending a ton of money to update my whole exaust . Now it does cost a little bit of money and dont exspect the same sound as if you did update the whole exaust system but the quality and sound cannot be beat also chrome exaust tail looks really good.I am sold on borla sound and quality.

    best 400 dollers i've ever spent!!!!!

    I love the note of my mustang. it's a real deep continuing note that makes you smile and have fun. As soon as i got it on the car I couldn't stop laughing and loved the sound so much I actually got pulled over by an officer on the highway for speeding. He asked what the hurry was and i replied... no hurry i just love the new sound of my car. no ticket that day.

    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 ❤️

    Top of the Line

    This exhaust took my V6 to another level. It has a nice loud roar that adds an awesome touch to my car. It's chrome finish looks great and top notch hanging from the bottom of my car. It was easy to have installed and I would recommend this exhaust to anyone. I have gotten complements galore after putting it on.
