Gerard,
I had that problem with my exhaust stack too. I took the whole pipe off, ( didn't want to cut a new stack ). My brother has access to stainless steel /forums/images/graemlins/grin.gif so I had him get me a piece for free of course /forums/images/graemlins/smirk.gif. I cut it to the right height, (just below garage door height), took it to the muffler shop to have them flare the one end. Muffler shop did it for free also!!
Now I have a tractor with a stainless steel stack,,, looks great,,, much better than black!! /forums/images/graemlins/grin.gif
