My brother has an 05 dr650 and after about 6 months he finally was able to get a two bros slip on. When I tried to install the s-bend the bolt hole nearest the head pipe was about half an inch off. I put an punch through the hole and tried to force the s-bend into place but I felt I would have to put to much pressure on the pipe and it would bend or snap something. We looked at the part numbers on the pipe and on the two bros website and they did not match. We sent the pipe to two bros and there engineers swear its the right part. Any body else have a recently purchased two bros? Did you have problems putting it on?
