Description


More Power. Give your 2011-2012 V6 the look and feel of a GT with a Magnaflow Street Catback System. This system is dyno-tested and engineered to deliver the signature Magnaflow sound and impressive power gains for your new V6.

Classic Musclecar Sound. Featuring Magnaflow's Street series chambered mufflers, this catback is designed to give your V6 a more aggressive note at wide open throttle without being too loud while cruising.

Stainless Steel. This premium quality catback is constructed from free-flowing, mandrel-bent 2.5" stainless for superior performance and durability. Finished with dual 4" polished tips, this system looks as good as it performs.

Application. Made to be a direct bolt on, this catback will bolt straight up to the factory hybrid H-pipe without any extra modifications required on the 2011-2012 V6 Mustang to give it a deeper, more aggressive sound and improved performance.

Note. Stock 2011 V6 Mustangs come stock with a mid-pipe that resembles both the H-pipe and X-pipe designs. This hybrid mid-pipe was created by Ford to help add additional power and sound to the V6 straight out of the factory.

  • It's difficult to say. What other bolt ons do you have? Elevation? Driving habits? Definitely you'll gain HP, my estimation at least 10. Less restrictive, you'll also notice better MPG, performance and of course- SOUND!

    Rattling and squeaking issues

    April 22, 2013

    I like the tone of this exhaust. Outside of that I am not satisfied. If you want to get an aftermarket exhaust get it done at a shop and have them get the part. In my case, I purchased from American Muscle and had a mechanic shop install the exhaust. After a few months, the exhaust began to rattle and squeak when driving over bumps. I have since taken my car to Ford three times and had them try to fix it. I paid the same install price a SECOND time to have Ford align the exhaust. Now, after getting my car back today Ford tells me that there is an issue with a sleeve/clamp continually loosening. They recommended contacting the manufacturer. The problem is obviously the exhaust unit. However, it will cost me hundreds to have Ford or any shop take the unit off and either put on a new Magnaflow exhaust or my old exhaust since the part was not purchased through them. I love American Muscle. They have great prices and free shipping. However, I cannot see myself getting a large part like this again online. I now have a $700 rattling/squeaking exhaust (excluding the hundreds I paid for install/reinstall). I have spent thousands at American Muscle and I wish I could get a refund. I cannot afford to pay to have the old exhaust taken off and a new one installed. In summation, I would not purchase this large part again.

    • Response from AmericanMuscle

      The Ford shop who recommended you contact the manufacturer was correct. Magnaflow has a lifetime warranty on their exhaust and they would be able to ship you out the necessary clamp to correct the problem. You wouldn't need an entirely new exhaust. Their phone number is 1800-824-8664 and are open M-F 7:30-5p PST. If for whatever reason they can not help, please give us a call and we'll get this taken care of for you!

    What stock should sound like...

    October 14, 2012

    First the install, like Fuel said in his review, a lift would be ideal but it can be done with a floor jack and two good jack stands. I had to put the jack stands on the highest setting and barely got the stock exhaust pipes out. The install was easy and straight forward, but ensure that the mid pipes are positioned properly or else when tightening the clamps it will cause your mufflers/tips to not line up with the cutouts in the rear bumper properly. This happened to the passenger side and we had to use a few washers to lower the rear hanger for proper fitment. As far as sound and performance, this exhaust sounds great. At start up it sounds nice and then quiets down to almost stock level after the car warms up. At cruise it is barely louder than stock, however punch and it sounds awesome. Definitely no popping or annoying ricer sound, only a nice growl. As far as performance, I think it might have added some power paired with the Airaid intake that I previously installed. Overall, I'm extremely happy with the exhaust and would definitely recommend it to anyone who wants an exhaust thats louder than stock but not annoyingly loud with decent performance gain. Should have come from the factory this way.

    Love the sound, but

    August 28, 2012

    The fit is not perfect. The shop had to cut the hangers and re-weld them as there was no way to have a gap of 1/2 inch from the plastic rear-end. Maybe i happen to have a bad batch, who knows. Also, the pipes after the cat, are AWEFULLY close to the axle, be careful to angle the pipes correctly as they will rattle against the rear axle. Otherwise, the sound is great, the tips look great. They are quiet while cruising, but can get very expressive when pressing the gas pedal. Perfect for me. They won't crackle/pop until you do the full headers (BBK LT)

    Easy to Install, Sounds Great

    June 04, 2013

    It was harder to get the OEM exhaust out than it was to put the Magnaflow stuff in. I had originally installed Pypes mid-mufflers into the OEM pipes, and hated the sound (plus the muffler shop that did the welding really did a terrible job, and the system had a rattle in it that was driving me bonkers. It also sounded like a Honda to me at WOT. Then I installed some BBK long tube headers, and that made everything behind the x-pipe sound even worse. Combined with the BBK headers, this system has a great sound. Since the tips are resonator tips, I didn't need to install my Vibrante resonators at all. My only complaint is that the tips hit the top of the exhaust opening. I'm going to take it to a muffler shop and have them do a better alignment on it. Install note - I had to install the driver's side front muffler hanger onto the muffler and then install the assembly into the car. It was easier this way. I gave four stars for bank/buck because I think the system costs too much (actually all cat-back AND axle-back setups cost too much). Once again, the sound is awesome.

    Nice Exhaust thats not overly loud

    May 26, 2012

    The magnaflow street exhaust is a good choice for someone who wants an exhaust note that sounds better than stock, but is not overly loud and won't attract any unwanted attention (from the fuzz). Install wasn't too bad, I did the install with the help of a friend, and it probably took about 4 hours. Having a lift is not a necessity, but it would definitely help cut down on the install time. I used a heavy duty jack and 2 jack stands and I was able to get the over axle pipes off, but you need to jack the rear of the car up pretty high or else you wont be able to twist them out( probably 18 inches or so). The hardest part was getting the factory mufflers out. Make sure you have some wd-40 and a rubber mallet to knock the stock axlebacks free. After the stock pipes were free, the magnaflows went in without much effort. In my opinion going with the full catback system is the only way to go. It increases the diameter of the piping from 2.25" to 2.5" for less back pressure, and helps cut a few pounds from the car (the stock exhaust is noticeably heavier than the magnaflow system). Also I noticed after removal that one of my stock pipes was squished a bit (which is bad for exhaust flow) After the install, I was very excited to start up the car to hear the difference. It now has a nice deep rumble. Its quiet when driving with a light foot, but when you punch it you can hear a nice throaty roar. (drive with your windows down and you will definitely hear it.) There is a tiny bit of drone in the 1.5k-2k rpm range, but not unbearable like I've heard from those who have the competition version of this exhaust. Just turn your radio up a bit and you wont have a problem. The only downside I've found with this exhaust is that the tips pretty much touch the rear bumper cutouts for the tail pipes, causing the rear bumper to vibrate, which causes my rear license plate to make an annoying noise. I fixed this by adding 2 more screws in the lower part of the license plate bracket. I'll probably play around with the exhaust this weekend to see if I can get it to hang a bit lower to stop the vibration of the rear bumper, but after adding the 2 screws the annoying sound is gone. Overall, I am glad with my purchase.

    Poor Construction

    April 04, 2014

    Once the exhaust was on it sounded great. However getting it on was an issue. The welded hangers, weren't welded on straight. The passenger side was welded at in inward angle and the drivers side wasn't welded on at a ninety degree angle. It took an extra hour or so to just adjust the hangers themselves. I expected better craftsmanship them that. I actually had to a cut a part in order for them to attach on. Sound is good, quality not so good.

    Great sound!!

    April 17, 2013

    Great sounding muffler. I have the bbk LT headers and an off road x-pipe and it sounds just like i wanted. It is a little raspy on the high rpm range but I believe that is the off road x-pipe. The fit and finished is good but the mufflers sit a little high. I might need to do some modifying to the hangers to get them to sit in the right place. Other than that everything was great. It was about an hour of work with a lift.
