I am very happy I decided to buy this m4 mid pipe it's the best purchase I have made. The quality was A++ very good welds and it fit perfect without any extra work. Once I put the M4 slip on with it unleashed the beast it's so loud and sounds so mean! I am constantly being told that it sounds amazing and it's so loud! When I ride with my buddies it completely drowns there bikes out. I am very pleased with my ice . If you want to open up your bike this is what you need. You won't be disappointed at all!!!!!!
