cant take the noise in the cab anymore from my FM40 dumped. Not ready for my dual exhaust yet, so I decided to fit my old 3" tail pipe up to the FM40. One problem, FM40 is dual exit. Tail pipe is single.....:whistling: Fist step, remove dumps. Remove piece left over from cut. Rough idea. Support tail pipe with jack stand. Mount muffler and tail pipe, align to desired postion. Tack Weld. Remove and weld. Mark and cut hole in tail pipe. Insert pieces and fully weld.
