so, I they shook something loose when they were cutting the pipe, so I had an exhaust leak and rattle @ the axleback "juncture." I hate mineke so much, if only they weren't so damn convinient. Anyway, harbor freight roxxorz my soxxors. I had to go get a deep well socket set, and some threadlock so I could fix the problem.
The exhaust should be sorted now, but I dunno why the studs are missing so many threads on the top half (on the flange side, not the "open" side). I just slapped some blue threadlock on there, stacked up some washers and tightened it down, so threads or not it should be in good shape lol. I haven't touched it since I bolted everything up to give the threadlock time to...er...lock, so we'll see how it goes.
