    Xtreme Aggressive Sound. Corsa Performance Xtreme axleback systems are acoustically styled and engineered to give your 5.0L coyote powered S197 Mustang a throaty aggressive sound under acceleration and a deep growl at idle all without interior cabin drone.

    RSC™ Technology. Corsa designs their mufflers using their own patented Reflective Sound Cancellation® Technology (RSC™) to give your Mustang an aggressive sound under acceleration and a drone-free experience while cruising.

    Quality Construction. Corsa Axle-back systems are manufactured in the USA from 3.0" diameter premium grade 304 stainless steel tubing for a improved exhaust flow and a perfect fit. The system features two straight-through mufflers that end with black chrome 4" Pro-Series tips, that exit in the stock location for impressive good looks.

    Application. This Corsa Xtreme Axle-Back Exhaust is designed as a direct fit bolt-on upgrade for the 2011-2014 GT and 2012-2013 BOSS Mustangs equipped with the coyote 5.0L V8 engine.

    • The Corsa Xtreme Axle-Back Exhaust is designed as a direct fit bolt-on upgrade for the 2011-2014 GT and 2012-2013 BOSS Mustangs. It has 3" Diameter Mandrel-Bent Tubing if the sizing matches up then you can use it with your system.

    The product description says 3' mandrel bent tubing, does this mean it'll bolt up to my 3' over axle pipes? or do i need to get the factory pipes?

    Taylor98

    • The Corsa Xtreme Axle-Back Exhaust does have 3" diameter mandrel-bent tubing, which would allow you to use a 3" over axle pipe. If you take a look at the product photo, you will be able to see a reduced portion on the pipe. This will allow you to slide the axle back into the over axle pipe and clamp it down.

    What is the difference between the Corsa Xtreme and the Sport Axle-Back?

    Jim

    • The Corsa Extreme and the Corsa Sport are chambered slightly different, which causes a difference in sound level. While the Corsa Sport is a louder exhaust, the Corsa Extreme is much louder and aggressive.

      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.

      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.

      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.

      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.

      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.

      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.

      No drone, all tone

      The fit and finish of this axleback is GREAT. The black tips go perfectly with my SBY Boss 302. But the most important part is the tone. It is amazing. Deep, throaty, pops and gurgles... combine it with the lopey track key idle and It could almost pass for a big block. No drone at cruising rpms. Sounds like open exhaust at WOT. Rumbles like a beast at idle. I've tried other axlebacks and catbacks, but I have never been this happy with one.

      The absolute best!

      The corsas deliver the best experience for your mustang period. They give you that butterfly feeling from the time you open the package. The quality of the product is clean and flawless. I wanted the extremes with the chrome tips however the black tips were on sale and for a price I could not pass up. It took me awhile to actually go through with black tips because I honestly thought they would look cheap or tasteless, boy was I wrong. I am so happy things worked out the way they did because the black tips are actually a glossy black chrome finish and it looks so good on any color. Now for the exhaust note, it's mean it's really mean, but it's only really really mean when you want it. You can take off from redlights Without causing a stir and cruise down the highway in peace. The tone is not like any YouTube video you have probably watched a hundred times but it is so much better and you will be itching to drive your car any and everywhere. The tone is deep and burly at the bottom then moves to a solid medium thump right before opening up to what sounds like to tigers fighting at 4000 rpm. It's great. If your worried about loudness it's really not I'm the kinda guy who went with the gt500 axle back first Because I didn't want loud. I heard the extremes once and had to have them. Inside the cabin is super quite, you will never get annoyed by it and you'll be able to hold conversations with all the girls who's attention you'll grab with this exhaust.

      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.

      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.

      Excellent! (Black Tips, Edition)

      Fit, Finish, Sound, Looks -- expensive but well worth it. Not too loud at low RPMs but when you get on it it gets loud. Has a nice sound at startup and idle. Very impressed and I've purchased a few different manufacturers exhaust systems and none were fit and finish like these. Protective covers on the tips and they have a nice rainbow color in the black (added some pics for the black) Install: It goes on pretty easy, use some soapy water to get the hanger grommets loose and you can pull them by hand. I would say say an hour or two should suffice, taking your time ensuring the tips are positioned where you want them before dropping it back down (oops).

      Worth every penny!!!

      Purchased this exhaust for my car when I just couldn't bring myself to cut up the rear bumper for the roush square exhaust. All I can say is wow, fit and finish is unlike any other exhaust component I have ever installed (and I've installed a lot of them) and they look killer. Bottom line, spend the extra money and buy corsa, you definitely won't regret it!

      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.

      Picked these up for my 12 boss 302 and couldn't be happier. Install with a lift took about 30 minutes hardest part was getting the one bolt that for positions just above the stock muffler with no room for a ratchet. Once the install was complete and the car started couldnt be happier car sounds like it should now not real raspy but just enough with an intoxicating snap crackle and pop on deceleration

      MUSIC TO MY EARS!

      I read all the reviews before I purchased the Corsa Xtreme to make sure this was the right decision, since these are not inexpensive. Nearly all reviews express the no drone, great looks, perfect fit, and ease of installation,... all true. Tame enough at idle to sit at a light along side Johnny law and not get the stink eye, or puttin through a gated community without the village idiots chasing you with torches or pitchforks. But words can't express just how GREAT these babies sound when you get the revs up, drop the hammer, and rip through the gears! (Disclaimer: Always at appropriate time and place) If you love the smell of burning rubber or gun smoke, stand as close to the burnout box/track as possible for a top fuel pass, and wanna see some blood during a MMA fight, then the Xtremes are for you. So glad that these are not standard on all Mustangs, these say I am different than others, I'm an automobile enthusiast that enjoys driving American Muscle!
