I slapped two of these on my Royal Enfield Interceptor 650. They sound so smooth and good. They are not super loud. They sound awesome, and look great on the bike. They weigh a fraction of the stock cans, and are much smaller. They bolt right on and come with everything you need except some copper exhaust paste. I say don't be snowed into paying a thousand dollars for some decent mufflers. These are serious bang for the buck and perfect on the bike. I really can't imagine the expensive ones being any better.
