Lol,u are a genius my friend. Why did I not think of something like that for the tti install? I have no fear drilling and threading taps for new bolts, but was a bit weary of drilling the end caps for the tti inserts,just in case for some reason I took them off and then the end cap wouldn't bolt on properly. Definitely gonna do this tomorrow, think I even have some 1/4x20 2" stainless bolts laying around. Good to hear u like them and the bike ran decent, I noticed the sound output and deepness improved after 1k miles or so
