hey I was just wondering if anyone else on here has ever heard of or done this to their stock headpipe. If you take off the headpipe and look down the primary tubes you will notice about one half inch in there is a weld--the size varies but obviously the more sloppy the more the restiction. Someone told me about it and said grinding it down would make a pretty noticeable difference. So I did it , it sure makes sense to me, I bet the weld was a good 1/8 meaning it was restrictive flow by 1/4 inch smaller diameter tube basically. But I havent got any seat time yet just got done thought I would throw that out there get soe responses and maybe help a few guys out. Well I will let you know if I notice a big difference when I get some seat time(I did run it and throttle response felt good.)
Merry Christmas and Happy New Year to all ;)
