    Flowmaster Pro Series Axle-Back Exhaust (13-14)

    May 14, 2014

    This Flowmaster Pro Series was exactly what I was looking for. The most deep throaty tone without all the snap, crackle and pop that you hear with some exhaust systems. I gotta tell you that it's such a serious improvement! It now sounds more like an AC Cobra 427 Roadster. Side - pipe exhaust note! The product was easy to install. Only thing missing in the instructions would be to cut the spot welds on the original factory clamps. The shorter chrome tips also gives a cleaner look overall. I would recommend this product to any Coyote owner. As always, thank you for the best products and great service and fast, free shipping.

    Lot's of compliments

    December 19, 2013

    They sound exactly how I want them except between about 2000-2200 rpm. I assume 6th shift on my automatic trans. This is about 73-79 MPH. Really loud in the cabin. Bump it up to 80+ and she quiets back down. It's been years since I've run performance exhaust and maybe how to drive them. But that's why bought her to drive and enjoy. Other than that steady window, these axle backs sound great!

    Good bang for the buck

    April 20, 2013

    Installed them in my driveway and finished in about two hours. I love the sound, but they were a little louder than I expected. They are still within an acceptable noise range for a DD. So far I'm loving this axel back and recommend it to anyone looking for something easy on the wallet, with a balance between quiet, and a good aggressive tone.

    Axleback Pro Series Exhaust

    July 03, 2014

    This is a great product. I changed out the mufflers on the garage floor, with little room to work under the car and the whole process took about 2 hours. When I finished I fired up the Mustang and the change in sound was dramatic, the sound was now deep and throaty and the burble was there in the exhaust note. Great product and I would recommend it to anyone. My Mustang now sounds like a car that has the 420 horsepower that the 5.0 came with.

    Great sound

    April 19, 2014

    Although it wasn't a choice, this took 1.5 hours to install and was pretty easy. The car sounds like a muscle car now and was easily the first choice in upgrades since the stock mufflers are no loader than my mini-van....now to the power upgrades!

    Perfect sound for a muscle car

    September 26, 2013

    I was really disappointed in the factory exhaust note on my new 2014 Mustang GT so I started searching. I am very particular on my upgrades and after a full evening of sound bites ( and an annoyed wife) I found the perfect fit with the flowmaster pro axle backs. I purchased, received them quickly, and installed in about an hour. The installation went very easily, the only problem being keeping the pipes up out of the way while removing the factory mufflers (the guy with the 2x4 idea had it right). It sounds perfect, just like a muscle car should. I was a little afraid it would be to loud but flowmaster nailed it. I wouldn't change them a bit.
