        Amazing sound!

        I love this exhaust. Yes, it’s on the louder side but it sounds so good and it is what I wanted. I have had many compliments about how great it sounds. I had it installed by a local shop and they were so impressed with this exhaust. They said it went together super fast and easy and they loved the way it tucked up into the Jeep giving lots of clearance for being on the trails. I waited well they installed my new exhaust. From the time they drove my Jeep around from the front of the building to the back and brought it back around to me with all the work done was shut 50 minutes. I have already been on the trails with it and it is not at all obnoxious as far as sound. Super happy with it
