    Best Sounding Exhaust

    I've had 3-4 different axle backs on my 2011 GT. The Corsa is definitely the best one so far. No drone at all, sounds great when cruising but is loud as a muffler delete at wide open throttle. I recommend this set up to anyone!

    How the 5.0 Coyote Should Sound

    This is the Perfect exhaust for your Coyote powered mustang. Corsa hit it out of the park with this axle back system. I have heard other axle backs and they seem to sound like a "rice burner" on steroids. The "extreme" system has the deep tone I was looking for. It gets loud when you hit the throttle but not to loud. It's quiet when cruising or at freeway speeds too. Very pleased with this system. This is how a big V8 should sound!

    The "no drone" choice!

    I wanted an aggressive sound when accelerating but quiet on the highway, and that is exactly what the Corsa Xtreme gave me. I have the Xtreme axle back and x-pipe. I had the system installed at Corsa. My car was used for design and fitment for the 2011 GT convertible system. They also dyno'd the car and I gained 11hp. I was given a tour of their facility as well. It was a very pleasant experience.

    Corsa nailed it!

    I put these on my 2014 GT and man... the smile on my face after starting it up said it all. I don't think I stopped grinning for an hour. Installation was easy with a jack and some stands. The sound is unique and perfect. A low grumble whenever you touch the gas changes to a Indy 500 wail when you mash the pedal. Absolutely no drone. Great fit and finish.... no messing around to line up. Not cheap, but great product & great warranty. Pony up the cash.

    Great exhaust

    Exhaust was a little quieter than I expected but has a very awesome sound and grumble, quiet while cruising which is also nice so it doesn't get on your nerves. Installation wasn't bad took around 45 mins. Great exhaust.

    Worth the Money!

    I have always stayed away from Corsa as they where more expensive than the Flowmaster. I can not be more stoked about an Exhaust than I am about the Corsa Extremes. It is best of both worlds. Quiet at idle and no droan at hi-way speeds but when you get into the throttle is turns beast mode. Everyone at the track is like that is sick sounding. The slant cut in the tip matches the body lines perfect. Took me about an hour to put on with out car lifted. It is the best exhaust I have ever had on a car! Thank you Corsa my Mustang sounds the best around these parts. Everyone thanks I have had engne work done.

    Corsa Xtreme, 2013 GT

    100% happy with this axle back. It is my second one on this GT and it hit the nail on the head. Nice rumble at idle and cruising. When you stomp on it, it delivers. It is worth the extra money. I recommend using the factory clamps for the best seal.

    Top of the Line

    I, as well, methodically researched different options for upgrading the exhaust on my Mustang GT. This seemed to be as good as they come for the best of both worlds - it is a bit louder at idle and throatier and it is downright impressive when you open it up. It isn't obnoxious like some set ups. I would highly recommend this exhaust to any first timers looking to upgrade who might be wary of something too loud. It's only loud if you want it to be. You may quickly discover that you want it to be loud often; the sound is addicting. The slanted tips are perfect and really add to the appeal of the rear end. Overall very impressed and would say it is worth the higher price. It is quality that you are paying for it is absolute all-around quality.

    Just what I was looking for!

    This was exactly what I was looking for! I wanted something that had that aggressive sound and roared when I got on it. But since I sank alot of money into a sound system I wanted it to be rather quite at idle and cruising and it definitely is. It's absolutely perfect. Instructions were clear and easy took about 2 hours to install.
