would this fit a 2013 mustang v6 3.7

Oscar55773

  • No. Inlet piping size is too big. You would need GT over axle pipes which are 2.75" for them to work.

will it fit if not why? will this fit on my 2010 mustang gt and if it dosent why? But i Know i will have to cut the bumper but that dosent matter

StangerBanger

  • No it won't. This is a ball joint connector. 05-10 cars use slip joint connectors at the axle back section.

Just how load are these Magnaflow Quad tip mufflers? I had Roushe on the car, but when I changed over to long tube headers, they were just too loud. From experience I know Magnaflow are pretty loud, but with the headers will it be too loud?

  • Hi, This Magnaflow Competition Quad Tip Axle-back Exhaust is very loud when especially when combined with Long tube headers.

I have a roush stage 2 will they fit in with my rear difuser or will i have to cut it to make it fit. (its the difuser that comes with the roush mustangs in 2011)

ethan

  • For the Magnaflow Competition Quad Tip Axle-back Exhaust (11-12 GT) it will not fit with the rear diffuser that comes with the Roush Stage 2 without modification. The diffuser is made for dual-tip exhausts and not quad-tips.

fitment with magnaflow competition cat-back system I got the competition catback series for my 2011 gt. Will these fit with that???

jmarcum

  • I have the same cat back, and no these will not fit. #1 this is a ball and socket design like the stock mufflers , they will however fit on your stock over axle pipes, our cat back is a slip fit. #2 this is listed as only 2.5", where out cat back is 3"..

How loud does this exhaust sound compared to the Roush Axle back? I currently have the roush, but I love the quad tip look.

DTT

  • Both Magnaflow Competition Quad Tip Axle-back Exhaust (11-12 GT) and the Roush Axle-Back Exhaust (11-14 GT, 11-12 GT500) exhaust systems are very loud and great quality. However when comparing exhausts each person does have their own opinion on them. I would recommend looking up some YouTube videos of the two exhaust.

    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.

    Classy

    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.

    Sounds great but you have to bend the hangers quite a bit to make fit

    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.
