Rated 5 out of 5 by from 2015 Mustang GT with Magnaflow Competition Series I purchased my Magnaflow Competition Series axle back system less than a month ago and it only cost about $80 to have it installed and what a difference it made. Nice deep guttural sound that sounds like it's coming from the bowels of the car. That in conjunction with my K&N cold air intake has completely changed my 2015 Mustang GT. The response in the pedal is so much better and the sound is awesome.

Rated 1 out of 5 by from Brand new mufflers burnt out on a trip I bought this product from another vendor to get the black version. At first I was completely satisfied with the product. Installation was a breeze and the sound was perfect. I recently took a trip from Denver to Birmingham, Alabama and the mufflers completely burned out. The sound now is obnoxiously loud and unbearably raspy. the sound is horrible, as if there were no mufflers at all. I am in the process of getting replacements or my money back. The worse part is I am so disappointed, I loved the sound of this system before it failed.

Rated 5 out of 5 by from Mustang Sounds like a Mustang Now I spent a LOT of time searching for just the right sound for our S550. There 5.0 sounds more raspy than the older 5.0s and I didn't like it. Magnaflow to the rescue! I wanted to keep close to the stock volume but wanted to hear a deep exhaust note. The Magnaflow competition is so deep and never gets raspy. With the factory resonator still in place, the MF Comp is only just a little louder than stock. This setup gives me exactly what I was looking for. The install only took 30 minutes. It was very easy.

Rated 2 out of 5 by from DRONES SOMETHING TERRIBLE I wanted a deeper tone not too much louder volume than stock. I spent a great amount of time looking at u tube videos, reading reviews listening to sound clips etc. The PJpony video was very helpful. I really wanted the magnaflow street axle back but was told it was not going to be manufactured. With some reservations, I ordered the axle back competition by magnaflow. I can't tell you how disappointed I am with the system! I had it installed by a muffler shop and left the factory resonators in place. I had removed the resonators on my 2012 Mustang GT and did not like the raspy sound it produced. My 2017 mustang GT 5.0 has an automatic transmission and as you know it shifts into higher gears at very low RPMS. Everytime it shifts, the exhaust drones like mad. You can hardly stand it. It is especially bad once it shifts into 5th or 6th. If you shift the auto manually to keep the rpm up it is not nearly as offensive. The bottom line is that if you have an automatic transmission, this is not the axle back for you.

Rated 5 out of 5 by from Easy Installation and sounds Great I bought this along with the MRT H-pipe. I did the install by myself in a few hours on ramps. If you have a lift and a helping hand, it should not take more than an hour. This combination sounds great and is much better sounding than the video.

Rated 2 out of 5 by from Drone issues You do your research, try to make the best decision based on that, as well as watching the install and sound clip videos that C.J. Pony parts put out. You trust the presenter when he says there is no drone and you "can barely hear it". Well the sound at hard acceleration is great but it drones way too loud on normal driving. I think I just made a $700 mistake and I'm considering putting the stock mufflers back on.

Rated 5 out of 5 by from Just the sound I was hoping for I looked at several axle back exhaust offerings and watched many videos and listened to audio clips and finally decided on the Magnaflow Competition axle back. The exhaust tips really fill out the factory cutouts and the sound is a deep rumble without being overly aggressive.
Date published: 2017-09-23
Rated 4 out of 5 by from Low tone sounds great! Been riding around with it for a month and I'm happy, it is very bassey, and at RPM 1500-1800 it can be a little too much bass for me, but once you are above that it is great! Nice to hear your mustang at an idle, finally sounds like a car with 435 HP should sound.

Asked by: Emys
Our kit is made to attach to factory components so if the parts you're installing replicate factory mounting locations, you shouldn't have an issue.

Will this system also fit on a 2012 GT/CS?

I have the MBRP street catback, will the MagnaFlow axle-back fit the H-pipe from the MBRP catback.

Asked by: BlackS550pony
We cannot confirm that fitment. Most likely it will NOT work. But I'm sure any exhaust shop could make it happen using a small piece of pipe or a portion of your factory exhaust.
