I love your exhaust better than our just as good as any other exhaust out there. I've never had a problem with any of my drd's I broke one from corner contact but we ended up welding it and it still sounded amazing and delivered the power I needed. I chose your exhaust over any others on the market. The low grumble on my 450 turns a lot of heads and everyone loves the sound. Thanks drd and keep up the good work.
