JBA 40-1666 Cat Back System.
It's best to do as instructions recommend & have a quality muffler shop do install. I installed mine on my back in the driveway & ran into some fit issues. Had to add 4" to both tailpipes as they were too short. Fortunately I have a welder & experience fabricating exhaust early in my career so it wasn't too big of a deal. Also had to reposition front hangers to allow muffler & tailpipes to hang straight & level. Welded all connections. Looks perfect & sounds awesome!
