I have recently bought a 2007 yamaha DT 125 r. The exhaust on it is very rusty and I would like to replace it, although i cant find one for a 2007 dt125r all the sites only do them for 85-03 n 04s . I don't mind wether its a standard full system or a sports one.Please could someone send me a site to get one or would older model exhausts fit...please help!!! thanks
