    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.

    Are these exhaust tips etched with the "MF" logo like in the only 3 customer submitted photos or are the tips plain with no logo or mark?


    • 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?


    • The Magnaflow Competition Axle-Back Exhaust is considered a louder axle-back exhaust that we carry, however, the overall sound level is mid-ranged. We would recommending listening to a few sound clips of the axle-back exhaust to see if this is a kit that is loud or quieter for you.

    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?


    • Yes and no. Yes to your question on this being an empty pipe, but no to your question on simply deleting your mufflers to achieve the same sound. Just because the mufflers are straight through doesn't mean they didn't design them specifically. The way all straight through mufflers are designed give them all unique sounds. The idea is the straight through design allows for the loudest mufflers.

      Review from Magnaflow Competition Axle-Back Exhaust (15-18 EcoBoost)

      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 (15-18 EcoBoost)


      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.
