      Review & Installation Video

      The Corsa Xtreme axle-back for the 2005 to 2010 GT Mustang is something that you should check out if you're looking for a 304 stainless steel axle-back that also happens to be one of the loudest available, but that doesn't have any drone, and if you don't mind paying extra for the Corsa name and quality. Corsa is known for producing loud exhaust systems that are high in quality with no drone, and top-of-the-line fitment and manufacturing, but they usually are on the more expensive side of things. The install for this axle-back is easy. It's gonna be a one-out-of-three wrenches on the difficulty meter. You can plan on spending an hour's time to get this installed. Corsa prides itself on its ability to provide an exhaust that gives a throaty sound under acceleration and a very deep tone at all times, and lots of volumes all the way around, without any drone in the interior. They're able to do this because they tune their mufflers. They've created what they call RSC, or reflective sound cancellation technology. This allows the axle-back to be loud under acceleration, but it eliminates the drone that you commonly get with an axle-back as loud as this one is. This is gonna be a five-out-of-five on the loudness meter, with one being a quiet upgrade and five being a very loud one. This system is one of the loudest axle-backs that we have currently available on the site, so if you're looking for loud and aggressive with no drone at all, you're in the right spot. Other than having a ton of volume with no drone, this axle-back is also made in the U.S. from 304 stainless steel. If you have a daily driver or a car that you drive a lot in all types of weather, I always recommend stainless steel, especially 304 stainless steel, since it's top-of-the-line when it comes to materials. It's gonna have the longest life and hold up the best over time. 304 stainless steel won't corrode or rust over time like aluminized steel would, or even some of the cheaper forms of stainless steel. The mufflers in the system are straight-through mufflers and they have mirror polished stainless steel tips. If you wanted a different look, Corsa offers the same system with black tips instead. And if you're thinking this is maybe a little bit too loud for your personal preference, Corsa does make a Sport axle-back that isn't quite as loud as the Xtreme here is. Like I told you guys earlier, this system is on the more expensive side when you compare it to your other options out there. You can expect to spend over the $700 mark for this axle-back. Corsa stuff tends to be more expensive because of the nicer features that this has, like the fact that it has no drone but a ton of volume, and that it's 304 stainless steel. So, if this is a little bit too expensive for you, there are a lot of options on the Product page when it comes to axle-backs for this generation. This is a bolt-on item, so you're looking at a very easy install. I'm gonna call it a one-out-of-three wrenches on the scale when we look at difficulty. Overall, you're looking at about one hour to get this all done. And, as usual, a lift would certainly make things easier for you here, but the job can be done on a jack and jack stands, as well, if you don't have access to one. This axle-back very simply bolts right up into the stock location, so you won't have to modify anything or cut anything. You're just looking at dropping your old axle-back, and the new axle-back will come with new clamps for you, so you don't have to worry about transferring the old ones over. When you go to install your new setup, it'll probably be easiest to leave everything a little bit loose until you have it all lined up, and then tighten it down. Wrapping things up here with the Corsa Xtreme axle-back, this'll fit the 2005 to 2010 GT Mustang, and you can check it out more online right here at

        4 2010 GT - Jimbo Installation Time: Shop Install


        These are so loud! Coupled to my catted long tubes and Y pipe. Even the Dyno tuner said, my God which mufflers are those? I told him Corsa extreme. He said this setup is insane loud. It was the first I heard it outside of the car. And it was shockingly loud! But at speed, in high gear, it whispers almost like stock, and NO drone. My poor neighbors! Buyer beware.......these are loud! They sound amazing on the downshift.

        Corsa Xtreme Axel-Backs

        Absolutely love these! Got the Xtremes for my dad’s ‘08 GT500 and am so glad I did. These axel-backs are more expensive than pretty much any other similar product on the market, but you really do get what you pay for! My dad and I installed these in a couple hours (took a little longer because we had to adjust the positioning a couple times) in the driveway. Had the Dad get in his car and start it up, and he could barely tell a difference (inside the cabin) from his previous (Ford Performance) exhaust! Yet when he got out of the cabin and heard it.. his car sounded nice before, but now it really roars. This really speaks to the quality of the anti-drone technology that Corsa uses. Even stepping on the gas and getting in the upper rpms, the cabin is still pleasant to be in- no drone whatsoever! This is an absolutely wonderful product, and I recommend this to anyone and everyone!

        Beautiful Sound

        Corsa is a very highly premium product so of course the price will be high. If you want a really aggressive and non-drone sounding Mustang and are really into how your car sounds. It’s great to just have Corsa Xtreme. Although I do wish the install of the passenger side axelback wasn’t as difficult. Since it is hard to adjust and the instructions sort of helped. Just took longer to install when your pipes are rusted up so it’s hard to move the axelback around. Although it sure is a great product and a game changer. P.S adding this with a BBK off road x-pipe makes these axelbacks sound extremely beautiful and loud.

        This is a quality product. I had no issues with fitment at all and I did notice that the kit comes with instructions on how to make adjustments for a better fit. Great exhaust note and no noticeable drone with stock manifolds and mid-pipe.

        Worth the money. Great quality and the sound is Awesome! So much better than stock. Not obnoxious at idle or low rpm, but sounds like a bat out of he'll when you open her up. Uninstall stock and install new was 2 hours.

        It's alright

        It's alright, I thought it sound was louder. It is not a 5 out of 5 on the loud scale. Going to add a x-pipe hopefully it'll get to what I expected.

        Corsa X

        I have a '07 Shelby GT with Kooks, (long tubes, high flow cats, X pipe) and Detroit Rocker cams. I left the stock mufflers on until I found a muffler I really liked. Checked the reviews and listened to almost all the sound clips. I knew I wanted it loud (not obnoxious) great tone and no drone. Finally decided on the Corsa Extremes. They are LOUD, great tone, NO drone, did I mention loud! Sounds like a NASCAR Ford now! LOVE THEM!

      My 2005 v6 mustang has a dual exhaust system installed on it. Will the corsa xtreme axle back fit on it ?

      • Yes, if you have a dual exhaust conversion on your V6 the Corsa Xtreme Axle-Back Exhaust would be compatible.

      Hey, will this exhaust work with a BBK high flow cat x pipe?

      • Yes, you can essentially pair any mid-pipe with any axle-back as they do not directly connect. As long as both match up with the factory over-axle and intermediate pipes, you should not have any fitment issues.

      Will they pass the CA smog test?

      • Yes, since the Corsa Xtreme Axle-Back Exhaust does not effect the catalytic converters it will still pass smog. We do suggest checking your local and state laws to see if they have decimal restrictions for how loud your exhaust can be though.
