I was drunk when I posted this last night but I am upgrading to 2 10mm exhaust mani studs on the ends of the mani. I have all 8mm studs right now, none are broken. I already have everything off, the exhaust/turbo/manifold so I figue I might as well do it considering I'm getting a 2g mani and I already have the studs. I just need to find a 90degree angle drill, maybe rent one or something and be really carefull when I drill.
