Corsa extreme black tips

The wrong tip was sent. They will resent the one I ordered. Very happy customer tips look great can't wait to install the exhaust!

Amazing product. I was worried there wouldn't be a noticeable sound difference with just the axle back and it's perfect. It was super easy to install and took about 3 hours from start to finish in my garage. Highly recommended

OMG! Beats all others!

I’ve had several exhausts on my performance vehicles over the years. Through months of looking for the best sound on my C7 corvette I went with the Xtreme exhaust and holy $*^%! If your looking for performance with a NO drone sound and bad *** sound that sounds better than other brands ( flow master, Borla and Magna flow, this is a must purchase. You will not be disappointed with the deep rumble and menacing sound at cold start up. If you have a manual and use the rev assist, the downshifting sound is incredible with the deep blurp and cracking sound is amazing. For maximum performance and sound you definetly will not be disappointed with this fantastic exhaust. Plus the tips look amazing. A must buy for any C7!
