Fit and finish are perfect. The other reviews are not lying. All tone, no drone. Saves me from doing full exhaust until it's time to do serious mods. Literally could not go back to any other exhaus ...

Hey I’m Justin with AmericanMuscle.com, here with my breakdown of the Corsa extreme axle back exhaust system fitting all 2011 and newer Mustangs. Corsa exhaust systems are no doubt one of the nicer options available for any Mustang, in addition to being one of the most advanced. Corsa incorporates the reflective sound cancellation technology or RSC as they call it, and give you the best of both worlds, an exhaust that’s going to be quiet and drone free on the highway while cruising, and one that’s going to absolutely scream and be angry whenever you’re on the throttle. Now if you’re not watching this video on our site already and you want to learn more about that RSC technology or the Corsa in general, just go ahead and click the link below to head back to the product page. Besides the technology that goes into these mufflers the build and quality of materials is also very impressive, the extreme utilizes a 304 grade stainless construction throughout, 3” piping, beautiful welds, and finally these mirror polished 4” tips, etched with the Corsa logo which as you can see do feature a very unique slash cut. Most exhaust will feature a straight up and down slash cut, but you can see the Corsa here utilizes a more side to side cut. That side to side cut actually features and fits the lines of the rear end in my opinion than the straight up and down cuts, just makes for a much cleaner appearance in the rear end. Installation shouldn’t involve anything out of the ordinary and can easily be done in about an hour using some standard hand tools. Before we jump into those sound clips I just want to remind you guys that we always try to bring you the best sound clips and exhaust clips possible, of course you get to hear a bunch of different sound clips in addition to my overviews so if you want to stay up to date with all the latest exhaust vids for your car, in addition to some other great content, just subscribe to our YouTube channel by clicking on the link below. Now let’s hear how the Corsa extreme axle back sounds compared to our factory exhaust.

    Review from Corsa Xtreme Axle-Back Exhaust - Black Tips (11-14 GT, Boss)

    Sounds as a 5.0 should

    Had roush and absolutely loved it but switched to corsa for less drone and slightly deeper and it was perfect. Amazing.

    Best exhaust on the market

    The fit is perfect and the exhaust note is music to my ears. The car has zero drone when in 5th or 6th gear and once its warm is almost completely silent when coasting. When you put your foot to the floor on the other hand it demands respect from everyone around you. 10/10 Perfect all around.

    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.
