Metal Twister 0 Posted February 28, 2012 Have a friend who needs to weld up a 2008 Yamaha YZ450Fstock exhaust. By chance does anyone know what grade S/Steel they use on there exhausts? Has anyone welded one up with sucess? Thanks for the help in advance. Share this post Link to post Share on other sites
Corpic 5 Posted February 28, 2012 316 should work well use lowest heat possible, if its a large area use a back purge to avoid carbide precipitation( cap pipe and purge W/ argon ) good luck Share this post Link to post Share on other sites

Im trying to find out what grade Stainless, if it is stainless? Ive heard rumors its not S/Steel. Have you ever welded one of these pipes? Share this post Link to post Share on other sites
PastaPilot 17 Posted February 29, 2012 Try to send a PM to christi20. Her company works very closely with DR.D racing and they make loads of exhaust products. I think I even heard a rumor that Dr.D makes the exhausts for GYTR. But that is just a rumor. Share this post Link to post Share on other sites
