Hey guys I bought another set of 2010 headpipes on fleabay and gutted them, had a friend tig weld them back up for me. Wow the heat reduction was awesome, could tell a big difference. Sounds better too I kept the ones that came on it just in case, but a question the bike seems to run fine no popping on decel do i need more fuel? I know that it is lean but I haven't done anything else to it it's stock. So will it lean it out too much? I do plan on stage one someday but not right now pretty happy how it is now.
