JJ

  • We do not have any sound clips of the Magnaflow Competition Axle-Back Exhaust w/ Black Quad Tips (13-14 GT500). We would recommend going to local car shows of checking online for some exhaust videos.

My GT is set-up for road courses and a I track my GT at HPDE's regularly. The loud exhaust note will need to be toned down...I will be adding mufflers in the near future.

    Amazing just amazing...

    Put them on my 13 GT500 less then two days ago and I've fallen in love. Had them installed by my local performance shop. Install took less then an hour. As soon as I started the car after installation the entire shop jumped. No one expected for a axle back to make that much of a difference. If you own a 13 GT500 this needs to be your first add-on not only does it free up some extra HP but it also gives your beast that race car sound.

    Too loud

    I bought the bbk shorty x pipe and long tube headers with it and installed them on my 2014 GT. The sound is just brutal and I love it. However, I have to point out that if you are a daily driver and you drive the car more than 1 hour per day, that loudness and drone will make you go deaf in a couple months. Also if you are going mad fast on the street, the cops can hear it from miles away. Besides that it's perfect.

    Wow - You want Loud & Aggressive? You got it with these...

    I simply wanted the most aggressive Axleback I could find and this is definitely it. Quad Muffler Delete. Finish is great. The black color is mean looking. Fitment took a one star hit only because it was a little difficult to align the driver side ---- needed some hangar bends to get the alignment correct, but not bad at all. Now, when I cranked it up, oh wow. Exhaust note is very aggressive and really turns this beast into a bigger beast. I don't really notice any drone ----- maybe a little at 1900-2200 RPM. Overall, if you are just going with an Axleback and you want loud, aggressive, and mean, install these. You won't be disappointed.

    a great product

    I just got the axel backs for my 5.0 GT/CS and their amazing, but for some reason the right one sticks out more the the left one and the machanic said it's longer than the left one and he suggested me to cut it and I didn't so I kept it that way. overall they're just amazing and I'm in love with the sound

    No Muffs

    I purchased this exhaust with the rear valance which was sold separately. I am giving the entire kit 4 stars instead of 5 because CJ pony parts sells them together at a cheaper price but the sake of convenience I still purchased the kit thru americanmuscle because there was a 15 dollar coupons I used but i still paid slightly more of 5 dollars for the entire kit. They gave me the option to call but I decided to dive in and purchase them anyway. The exhaust package was huge when I received it from the mail. Since I wasn't familiar in installing the exhaust myself or the rear valance I taken it to a shop to get it done professionally. I was quoted at 150 dollars which seems fair. The installation taken 3 hours (since the old exhaust needed to cool down a bit). When I got the call to pick up my car the mechanics were complimenting the sound. The moment I turned my ignition I was immediately overwhelmed how loud she roared. Even on when she was idling she growled like no ones business. I was definitely pleased how she looks on my car. I love the fact these exhaust have no muffler and how it compliments my car being white. Not only it will make her loud but I had noticed my car has gotten faster in accelerating. This is definitely worth your purchase if your planning to buy a new set of exhaust. It will really make your car look like your driving a gt500. You can't go wrong.

    The perfect exhaust for a modern muscle car!

    Great exhaust overall. This exhaust is exactly what I was looking for; it has a great blacked out look and is extremely loud with a great tone. This exhaust is not for the faint of heart or for anyone that wants a sleeper. The only downside is the price; however, if you want a quality product, it usually comes at a price. Finally,it fit well and was an easy straightforward install.

    2014 GT500

    I've never had Magnaflow products before, but I am thoroughly satisfied. The weight saving is ridiculous and the sound is awesome. Highway drone is pretty common with aftermarket exhaust; I don't notice it at all with these. In town driving around it sounds like it should, then on the highway they aren't noticeable. A++ My only wish would be that they were made in chrome, but that just has to do with Magnaflow. American Muscle is a class act, my exhaust were shipped and received before I even expected them to be in stock.

    Loud and Mean Muscle!!

    I have a 2014 red with white strip shelby gt500. The quad black tips look better than the stock chrome tips in my opinion. They match the rear black bumper and stick out just a little bit more than the factory exhaust. Install was very easy I have my own lift so it took me about 40 minutes to do a perfect job. Had to block the existing pipe upwards with a wood block to wiggle the factory exhaust out. Took me about 40 minutes for both. Easy to adjust to center the tips out the back. When I started the machine up for the first time I was so amazed. Its so much louder and deeper when your behind the car you can feel the rumble through your stomach. I felt like a kid on X mas that just got the best gift. I took it on the HWY and gave it some gas it almost sounds like it wraps but has such a mean tone to it. The first time I had it out I got so many looks, people wanting me to rev it up. It draws a ton of attention. I will be the guy that starts his car up in a parking lot and everyone turning there heads to see what kind of monster machine is that. There definitely is some drone inside the car even in 6th but it's tolerable. I absolutely recommend this product if you want something loud, and something that fits perfectly. I showed some friends the exhaust and they all said its the sickest sound they heard yet. Great job by American Muscle on the fast shipping to Canada, and by Magna Flow.

    Boss to Hoss.

    Easy install at my local muffler shop. Less than an hour with two guys working on it. Exhaust was good before but now it is HOSS. Sounds like a elephant in a tunnel. I love it. I keep making excuses to drive more. Very noticeable at start up for at least a mile around. Black looks great. Can't hear the supercharger anymore but I don't care. I can blast music and hear the engine well. Burps and gurgles on deceleration. The stock 2013 Gt500 mufflers were heavy. I bet I saved 20 pounds. My original exhaust stuck out an inch longer on the right side, and the Magnaflows do as well. Thanks for the fast shipping and solid packaging.

    Exhaust

    The shop had the exhaust installed in about 45 minutes. Got the car off the lift and started her up. The sound was incredible! I really don't notice a lot of drone at speed. When I get on the gas the sound comes alive and let's people know that you're coming through! I would recommend these to anyone!

    SOUND CANNONS

    If you want a LOUD exhaust, these muffler deletes will do the job. I upgraded to these from the Pypes "Pype Bomb" muffler deletes for the quad tip look. I really love the way this product looks on my black '14 GT. The fitment is excellent, SO much better than the Pypes. I did have to bend the hanger bars on the driver’s side one a bit to center it, but no big deal. Love the look and I see a lot of heads turning and eyes staring at my tail pipes now. I had to modify my rear bumper to accommodate the tip which made me nervous, but in the end it was actually a lot simpler than I expected. No joke though these things are obnoxiously loud when you get on it. Great burble at idle though. Thumbs up.
