      Hey I’m Justin with, 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.
