This product took the mild factory rumble and changed it to what a V8 sports car should sound like. Love it !

Any Drone? if yes? how bad and at what range? I love a throaty exhaust, but the drone kills. Even with the Shaker 500 the drone over powers the radio to death. So I am looking for something with growl, but easy on the drone.

    Great Axle Back for a great price

    Well I put on my heartthrob axleback a few days ago and man was I impressed. First the install was simple and lined up perfectly. The only problem I had was putting the exhaust hangers after the mufflers on. Had to unscrew the three bolts holding the hanger assembly on and do it that way. At idle is just a bit louder but when you step into it its another animal. Has the backfire pop and crackle which I like but its not overpowering. There is a very very very slight drone at 50 in 6th gear. I have the 3:73 gears. But its nothing like my old car. For the money no one can compare to this axleback. I highly recommend it. And AM shipped it to me within a day!!!!!!!! Best website Ive ever purchased from

    GREAT sound and very easy instillation.

    I work for a Ford Dealership and I see lots of people install lots of different types of Exhaust systems on their Mustangs. So when I bought my 2012 Mustang GT, I decided to go with the Heartthrob exhaust. It sounds amazing and its a lot cheaper than several other systems on the market. It was very easy to install and everyone at work tells me it sounds really good when I leave for lunch everyday. A great choice and a great price. No regrets

    Great exhaust for the money!

    Considering most other axle-back kits run 400-500+, this is great bang for your buck. I installed it in an evening. Wouldn't have taken more than 70 minutes but I decided to sand them, clean them, and then paint them with black high temp paint. I would definitely recommend painting them, especially the welds. Quality is about what you'd expect for the price. Aren't the best looking things out of the box but a little elbow grease and a few hrs they are nice. Fitment was a bit of a pain... Had to bend all of the hangers, some quite a bit, to get them to fit just right. All in all though it wasn't too bad. I would recommend unbolting the front hangars (towards axle) with the old mufflers and install them with the new ones. Makes removal/install way easier. Would definitely recommend! Drone isn't bad at all at hwy speeds. Sounds amazing! Stock is way too quiet, this puts a deep, loud growl in the beast. AM shipped same day UPS, exceptional service! Best online part site I've ever used.

    IF YOU LIKE LOUD :)

    The install went without any issuse. I like the way they stick out a little farther than stock especially with the angle the tips are cut. IF YOU LIKE LOUD these are a GREAT choice. I love the way they sound 95% of the time. The only issue I have is despite all the folks saying no drone in my case there is a DEFINITE DRONE @ highway speeds (2000RPM). Supose to go on ten hour trip soon and I'm concidering putting in some insulstion in the trunk or wearing ear plugs. Other than that their GREAT!!!!!!! ps. The tips aren't really all that polished but I had some good stainless steel polish(for my grill) which helped them look better

    OUTSTANDING PRODUCT

    I installed a pair of Heartthrob Flowpack axle-backs on my 2014 Mustang GT this afternoon. When I cranked her for the first cold start, a HUGE smile can on my face. I said, "WOW, these mufflers are AWESOME!!!" I was immediately amazed at the deep tone and rumble. They quieted some as she warmed up. I took her out for a test run and noticed no drone at all. At wide open throttle, she screams. This is what a Coyote Mustang GT is supposed to sound like. I recommend these mufflers to anyone that wants to upgrade from the quieter stock exhaust system. You can't go wrong with Heartthrob Flowpacks.

    excellent sound

    put this system on my 2013 GT and wow it sounds great i have not expeirenced any drone at all and at highway speeds you can barley here them. how ever you step on the load pedal and they come alive. i have gotten many compliments already on the sound. the tips sit sideways in the opening to push the sound to the outside not just straight back. very throaty on start up and under throttle. i recommend this product.

    Awesome sound!!

    Exhaust is awesome, sound is great. When just cruising is just slightly louder than stock, but when you get on the gas it is another animal. Had to drop the rear hangers to install, but other than that they lined up great, best exhaust in my opinion for the money. Thanks AM

    excellent

    I wanted to take the muffler out all together, but taking the muffler out of the equation would have been illegal. so i bought this system. the tips are welded to the muffler, but i like the fact that they are slanted like the rear bumber fascia, and not come straight out. the exhaust is loud when you are taking off from and stop or even just accelerating. i love the way the exhaust sounds.
