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

    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

    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!

    Deep Muscle Car Sound - Look no further....

    These Flowmaster Pro series mufflers have the perfect deep sound that a Mustang should have and it's not to loud either and with NO popping backfire like others mufflers have. I like that the mufflers have a straight through design to allow for better exhaust flow. Plus, they feature something Flowmaster calls "Laminar Flow" probably a marketing gimmick - but these Pro series mufflers are awesome. I still have the factory H pipe and resonators.

    Good bang for the buck

    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.

    Awesome sound!

    i was looking for an old-school rumble and these mufflers got me just that. i notice a lot of people turning around to see whats coming as im driving through town or a parking lot. Lots of thumbs up!! Fitment was great and install was easy. Did the install by myself in an hour using a jack and jack stands. The tips look much better than stock now that the cut-out in the bumper is filled up a little more.

    Axleback Pro Series Exhaust

    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.
