    Guys, is there anything special I need to know about the installation on a convertible? Specifically 2016 Ecoboost Premium Convertible.

    • This exhaust will fit all 2015-2017 Mustang EcoBoost models without any issues. This includes both fastbacks and convertibles.

    I'm looking for a low guttural sound that will fit on a 2017 EcoBoost Convertible. Convertible is the first hurdle! Any suggestions?

    • Any of the exhausts that are 2.5" tubing would fit the convertible models perfectly if you purchase a 3" exhaust, then the additional bracing would need to be modified. The exhausts that we would recommend looking into as well as this competition exhaust would be the Flowmaster American Thunders exhaust, AWE Touring exhaust, and the Borla ATAK.

    I've got the magna flow street catback. Can I just un clamp the street mufflers and clamp the competitions on or do I still need to do some cutting?

    • You will be able to swap out the mufflers, however, the mufflers may not be a bolt-on installation and may require some cutting to get these on your current set up.

    Is this the same as the GT version?

    • The mufflers used in the Magnaflow Competition Axle back are the same for both the V6 and GT. However, they are shaped differently, for proper fitment on each vehicle.

    • These tips will be etched with the Magnaflow 'MF' on the sides.

    Is this exhaust on the louder or quiet side? The website says it's loud but in the video Stephanie says it's moderate to quiet. Which is it? 1 answer
    Hey when she says its a straight through muffler design what does that mean? Does that mean that its an empty pipe and i might as well cut the muffler off and i will get the same sound? 1 answer

      Review from Magnaflow Competition Axle-Back Exhaust (15-19 EcoBoost w/o Active Exhaust)

      Great muscle car tone, perfect loudness

      I installed this axle-back on my 2016 Ecoboost Mustang Convertible and this exhaust looks great and sounds fantastic. I'd agree with what Stephanie says about the tone and loudness. I was very concerned that the exhaust I chose to buy would be way too loud, but the Magnaflow is a perfect amount of loudness for me. Convertibles have floor pan bracing to add rigidity to the frame due to the removal of the roof. If you have a convertible, make sure the exhaust you choose will accommodate the floor pan bracing. This exhaust fits nicely above the floor pan bracing. However, after an hour or so of driving after installation of the exhaust, the axle-back seems to have shifted slightly to lay on the bracing structures. Now when I drive over certain bumps, the system clanks/rattles a bit, hence the 3-star rating... all the bolts were torqued to the proper specification, too. I'm looking to resolve this issue by loosening said bolts and moving the elbows up slightly so the system is no longer resting on the bracing structures.

      Sounds Great! Fits Great! Easy to install

      Signature Magnaflow deep tone, Oh, man! I would expect nothing more out of a Mustang V6. It is definite the most deep growling sounded axle back in the market, I would like to upload a sound video, but trust me it just sound 10x better when you hear it in person. with the factory resonator in place it won't have any raspy poping can-banging noise and it won't wake everybody up at night but definitely loud enough to give that muscle feeling. BUT you have to deal with a noticeable DRONE at certain RPM, I can deal with it, Can you?

      Review from Magnaflow Competition Axle-Back Exhaust (15-19 EcoBoost w/o Active Exhaust)


      Installation was pretty easy on my brothers new ecoboost, we used a saw to do the cutouts. This axle back brought the car alive! Totally worth every penny.
