stupid question - where do my tailpipes go?

I used tti system and they put the pipes under the frame rail which put the pipe exiting center of the factory cutout. The right side didn`t have the cutout, but would wind up under the rail also, and slam up against the tank hanger like yours too.
I devised a bracket that hangs from the inside of rail towards tank and turns under. There was a factory hole in the outside of frame that I transferred through, I then enlarged the outside hole to accept a deep well socket. The bracket I welded a crushed lock nut to "I think". Another words It was a royal PIA to get that pipe equidistant on the car but turned out good and is still hanging in there, pun intended :)
