In between working on the 4855 I took a look at the exhaust on a 1655 I bought at last years FFA auction. It had a bad exhaust leak. Found the threaded in exhaust pipe came loose and PO ran it that way for a long time thus removing all the threads.
The holes for the bolt on flange were still good so I cut a flange and pipe off one of the P series mufflers I have and used that. I also wanted to convert it o a verticle exhaust while I was at it. I fabricated a crossover pipe using the P series flange and 1.5" pipe.
I'll Post more pics when I get the rest completed.
