Looking for info on converting stock SRX 440 pipes to GYT pipes I have seen it brought on other snowmobiling forums and was wondering if anybody know of where I can get this info from. Thanks!
The specs you are looking for are in the 1976 Yamaha SRX mod racing manual. The 77 pipes are different and the 76 pipes are very close to 78-80 pipes. Reproduction manuals are sold on ebay. Jeff Wurl
