        Perfect sound

        Exactly the sound i was looking for. I get endless compliments about the sound of my car. Fitment was decent considering the price and the template was not great, but if you put in the time and effort it will work out. Really gives your car that angry sound of a V8 everyone is looking for!

        Old School

        They remind me of an old school v8 sound. They sound mean and one of the best v8 growls out there. I have it paired with BBK short tubes, pypes off-road, BBK X-Pipe, and LTH Over-Axle.

        Pretty Good

        For anyone wondering this exhaust will also fit a 13-14 GT with the GT500 rear valence. Prior to this exhaust I had the Roush, which I will admit was louder at high rpm and did not drone at all. The Magnaflow's are much deeper than the Roush and do drone a bit at low rpm in 6th gear, but I don't mind. Overall, can't beat the quad tip look and deep growl from Magnaflow.

        I currently run stainless works longtubes and offroad x pipe. I had the pyoes super system catback and it was stupid loud, i love a loud mustang but holy cow haha. I swapped the pype bombs for this axle back keeping my mid mufflers and its perfect! The sound is rich deep and clear. Doesnt crackle like the old setup, my mom said it sounds classy and powerful, this is a great system and ive heard alot, these even sound better than the borlas on my last stang. Tips are great the car just sounds amazing. My picture is the kona blue one with paint matched lowerbody molding gloss black decklid and gt500 wing, which i ordered from here pre painted. Perfect color btw.

        Quad exhaust

        This is by far one of the best exhausts that I have heard for the 5.0. My car gets looks everywhere I go. It looks great and fits perfect. Take your time when cutting the bumper. It took about an hour and a half to instal with simple tools. Overall, a great buy!

        Magnaflow Competition Quad Tip Axle-back Exhaust

        Great sound, well built. On my mustang I didn't have to bend any metal at all but you do have to cut your rear bumper to make it fit which was really easy to do with the stencil that came with the exhaust system.

      Where can I get the number/diffuser to help fit the quad times for 2011 Ford Mustang??

      • Unfortunately we do not currently carry a rear valance for a 2011 Mustang that would properly house the Magnaflow Competition Quad Tip Axle-back Exhaust. You may need to modify your your stock bumper to install these, a template is included with the exhaust.
