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.

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.

    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!

    AWESOMENESS!!

    The Corsa Extreme is the perfect addition to my GT. It has a deep exhaust note I was looking for and it doesn't have any drone on the highway. Installation was straight forward and easy in my garage. You cannot go wrong with this exhaust.

    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.

    Perfect

    The installation is very easy and direct, it took me about 40 minutes with help. The exhaust note is perfect, I compared it with ford racing and borla Stype and I was thankful that I bought the xtreme. I always get compliments about the sound and it felt like Im in a new car. Its so quite on the highway. The shape and the design of the exhaust is unique and different than any mustang exhaust. Its just perfect
