Description
See our 2011 GT Project Car Now

Add Horsepower. Stop choking your 5.0 with a stock exhaust and enjoy more horsepower with a Magnaflow Competition Catback. By reducing backpressure and giving your Mustang GT or GT500 a free-flowing exhaust, you'll see great power and torque gains. In fact, our 2011 Project car has this same system with the off-road x-pipe, and was dyno tested with a peak gain of 19 RWHP and 18 ft-lb of torque. Plus, you'll set the stage for future mods.

Aggressive Musclecar Sound. Give your 2011-2012 Mustang GT a deep, aggressive rumble that will make lesser cars clear a path at lights with a Magnaflow Competition Catback. This premium quality exhaust features free-flowing, straight-through mufflers that increase power and give your GT or GT500 an unmistakable musclecar sound.

Magnaflow Quality. Each piece is made from 3" mandrel bent stainless steel tubing for long life and a perfect fit. The straight-through mufflers end with brightly polished 4" stainless tips that exit in the stock locations for impressive styling.

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 your 2011 or 2012 Mustang GT or GT500 to give it the deepest, most aggressive sound possible.

You want it loud?

Could not hear car well enough to shift as desired before; no problem now... My 2012 5.0 sounds mean and lets you know it is not a stock GT. Be aware that it can be loud enough to cause problems with sync

Sounds like a supercharger!

I noticed a better throttle control with this combo. Car has a slight whine/whistle now just like a supercharger. I have had people ask if I have a supercharger. Well worth the money!!

  • Unfortunately, it will not fit the 2013 GT. Magnaflow has totally separate systems created for the 2013 models. We are set to have them available on the site in the very near future!

    You want it loud?

    Could not hear car well enough to shift as desired before; no problem now... My 2012 5.0 sounds mean and lets you know it is not a stock GT. Be aware that it can be loud enough to cause problems with sync voice commands (I have to let off gas and hold in clutch to get it quiet enough to say a command)If you want loud and mean muscle car sound this is your exhuast.

    Loud and Bad@ss

    Loud is an understatement.... I love this exhaust because the car sounds mean. This plus a CAI and Tune makes this car a true BEAST. You can hear this combo blocks away so if you are afraid of a loud super aggressive bad@ss exhaust look elsewhere.

    truly excellent sound

    Had a Pypes Mid Muffler on my 08 Stang.I thought that sounded great.Wait until you get this one on.Has a wonderful tone to it, that iv'e never really heard before.Can't go wrong with Magnaflow.Took about an hour for a mechanic to bolt on.The looks you get from people when you get on it are great.

    2011 Mustang GT Exhaust

    This exhaust is for people that want an agressive exhaust, power, and a nice deep rumble in the lower RPM's. In the higher RPM's it screams. Not for those that want just a little more rumble.

    GREAT SOUND!!!!

    Sounds Great and looks great!!! Has very deep rumble and aggressive note! If you want a louder aggressive tone I would surely recommend!!! Not for someone looking for slightly louder than stock exhaust.

    Catback Exhaust

    I am extremely satisfied with the exhaust. I love the rumble sound. I had the high school auto shop install the system and it only took them 1 class to install(around 90 minutes) The kids loved installing it and they loved the sound also.

    Best 1st Mod for Any 2011 5.0

    Absolutely awesome. 1 HR install. Perfect fitment. Sounds like a race car. Definitely freed up some horses. This is what this Pony is supposed to sound like. Love the throttle response. Falls back to idle a bit faster and pops as it does. Just what I wanted.

    Great sound!

    Great product. Well worth the money! If you don't have access to a lift find one! Nearly impossible to get factory mid pipe over the rear end to remove without a lift! But I love it now that it's on!
