I have two questions, both have been discussed here. however i was unable to retain an actual fool proof solution. i installed the agency power exhaust and have the ground wire hanging, a lot of members dont care about it, but i do. has anyone ever welded or installed thier own grounding onto the actual ap exhaust? pictures would be helpful as well. and about the piping touching the passenger side rear differential causing rattling. I managed to get the fittment to where there is no contact on the bumber gaurds however it touches the differential and there isnt much room to move the hangers. has anyone tried a heat wrap to put between the pipe and differential maybe??? other suggestions are welcome.
