    Best exhaust on the market

    There was tough choices on what route to go with, cheap out and go to a exhaust shop and have them cut off my mufflers or go with a catback. The most popular ones that came to mind was Corsa and Borla I went with the Corsa and I’m more then satisfied. The install was easy and the build quality is top of the line, overall it’s worth the price and wait if you prefer quality

    Corsa Extreme

    It’s everything I was hoping for. At low rpm’s you get that rumble and when you get after it the extreme just screams down the road. Glad I didn’t cheap out and get a lower end exhaust. Worth every penny. Only issue I’m having is the one of the mufflers keeps shifting down. Have had to reposition it a couple times. Other then that it was a great investment. Well done Corsa

    Amazing exhaust system. Easy to install. Looks amazing and sounds amazing. Burbles more than it pops but still sounds very good. No drone!
