Most any farm supply store (TSC, Napa-type stores in rural areas, etc.) carries after-market mufflers for tractors. Most of the farm catalogs, like S h o u p, V a l u e-B u i l t (without the e & u, have to get past the censor won't even try to list the web sites [wow, even my first effort didn't pass any more - apperently you can find the mufflers here on the web site advertisers as well?]), and so on have the full range of mufflers available. Some carry a few, some carry a lot. But most likely you can find something that will fit, even if it was not made for your tractor specifically. Stanley seems to be the biggest maker of after-market tractor mufflers, at least in my neck of the woods. Some combine mufflers are actually horizontal - like a tractor muffler, but laid on it's side, you could add a bracket and shoot the exaust to the front! Both my old JD & my middle ages Gleaner have such mufflers. Certainly your dealer won't approve of this, as you are not buying from him. :) And it might change the sound, fumes, and look of your tractor, which might not be acceptable to you. A used muffler is not returnable, so I'm warning you, try this on your own nickel, the results are not always great or what you wanted. This is an experiment on your part. But it is possible. The catalogs list the inlet & outlet & heights of these after market mufflers in most catalogs. The one for your tractor will probably be the same as JD original, but some other muffler may match the sizes but be shorter. Most tractor mufflers have 6-8" of pipe above the top of the actual 'muffler' part - surely you can hack off your 'couple inches' unless you meant a foot or more - at which point, how will you fit in the door - can get to the point where you are putting yourself in danger of squishing in the door frame..... --->Paul
