Description
Free Flowing Exhaust. Magnaflow delivers the ultimate exhaust for the 2011-2012 GT or GT500 with this Street Catback Exhaust. By reducing back pressure for a free flowing exhaust, this catback produces more power and torque where it belongs - at the rear wheels.

Classic Muscle Car Sound. The Magnaflow Catback Exhaust System includes a set of two Street Series Mufflers that feature a free-flowing, straight-through perforated stainless steel core, with stainless mesh wrap and acoustical fiber fill to deliver that smooth, deep muscle car tone.

Quality Construction. Each piece is made from 3" mandrel bent stainless steel tubing for long life and a perfect fit. The Street Series mufflers end with brightly polished 4" stainless tips, that exit in the stock locations for impressive looks.

Application. Made to be a direct bolt on, this catback will bolt straight up to the factory Mid-Pipe without any extra modifications required on the 2011-2012 GT or GT500 Mustang to give it a deeper, classic sound.

Will the magnaflow x pipe (not the offroad one) clamp on and fit with this exhaust system, or will there be cutting involved?

  • Zero cutting involved, its a direct clamp or bolt on

I have this catback already and... I plan on installing the BBK long tube headers and BBK off-road shorty X-Pipe. Will the Magnaflow Street catback that I already have connect to the BBK X-pipe?

    Magnaflow street catback exhaust

    I took my time with the install just to make sure I did not have any problems later I installed the off road x and full three inch catback system. My exhaust is a little louder because of the off road x but I highly recommend this product if you enjoy the sound of a 5.0 this is for you

    Instructions said it would take about 2 hrs give or take, but the it only took an hour tops and thats while including clean up. Gave my ride a nice deep sound. It's mean and not that annoying loud either, just the right sound overall. That is for my taste. The only bad thing i have, if its even considered bad, is that when it arrived some portions were scuffed and minor dents but they were in the portins that could not be seen when installed.

    Very Nice Sound

    Okay well before I bought this I read the reviews and one guy said it was a nice sound that barely intruded the inside of the car, so I bought it...Well I'm not complaining, but it is a little louder than that, but it sounds awesome...! I wanted a deep rumble and I got it, but when you get onto it it is a very nice sound, but I will say I installed the Offroad x-pipe at the same time so that may be why it is louder, either way a very nice rumble, its PERFECT....! Install was nothing, I did it on jackstands, and couldn't get up hight enough so I had to jack up the rear end enough to unhook the shock and swaybar link and slowly lower the rearend just enough to install the pipe over the rearend housing, but that took 5 minutes per side, not a big deal considering I saved hundreds on install bucks....anyone could do the install with any mechanical skills....

    Magnaflow quality - can't beat it

    Have stayed with Magnaflow exhaust systems on my Mustangs ('04 and a '12 GT's) and am very pleased with quality and sound. '04 went without a hitch. '12 was another story - fit was poor but warranty response from American Muscle and Magnaflow was outstanding. Every product line can have occasional an bad part get through the system, it's what they do about it to make things right that counts. A replacement system was expeditiously sent out and first system picked up without any cost to me, as it should be. At any rate, replacement system looks and sounds great and as I said in the Review title "Magnaflow quality - can't be beat"

    Excellent quality Magnaflow is known for with good fit and finish. Sounds great, couldn't be happier. Nice low, throaty rumble that only slightly intrudes inside the car.

    Oustanding quality, performance and weight reduction

    My new Magnaflow catback for my 2012 Boss arrived Friday. It was packaged with care - bubble wrap, foam, and tape to ensure everything arrived without a scratch or dent. Parts looked beautiful and went together perfectly. Car has been lowered 1.5 inches in the back and still no issues with fit. Sounds great and takes approximately 24 pounds of weight out of the car. Stock Boss mufflers alone weigh about 48 pounds with the front hangers attached. Entire Magnaflow system with midpipes, mufflers, front muffler hangers and clamps came in around 50 pounds. A few extra HP and ~24 less pounds less weight. Hard to beat.

    high quality

    this is an amazing looking system, the mufflers are flawless and look like mirrors. its a shame youll never really see the exhaust under the car. This exhaust is a straight through no chamber design, with a offset input. i have this installed with a JBA off road x pipe and it is amazingly deep sounding yet very quiet in the car. its also fairly quiet but when your at wide open throttle it will still have a decent volume to it.

    Don't try this without a lift

    It would have been a breeze with a lift. Without one you will need a saw to cut the pipe and drop the rear axle to install the new ones.
