That is welding splatter from where the spring hook loops are welded onto the can end cap.BT what is the sorta splatter stuff in the top right of your pic?
also what color is the inside of the exhaust tip? just wondering if they all are abit on the rich side, i read a few posts that some were abit rich, I installed my Gen3 this weekend but not completely finished yet
And yes, I think it runs just a tad rich down low. Gives just a hint of a puff of black smoke if you blip the throttle from dead idle. Seems to be common for Brock maps to run just a hint rich according to what I've seen posted by others and my experience with mine.
Oh yeah, the inside of the exhaust tip has a super thin, light to medium greyish color residue. No black soot.
