repairman 7 #1 Posted February 26, 2011 does anyone have some info on exhaust systems I am thinking of making a new exhaust out of 3" pipe cap the ends and make a tail pipe would like to know basic rule for expansion size for the right amount of back pressure this will be used on a 14hp Magnum I have the original exhaust but it is 5.5" around and 11.5" long just to big to use on a square hood tractor :thumbs: Share this post Link to post Share on other sites
sorekiwi 761 #2 Posted February 26, 2011 There was a thread on MTF (I think) that was talking about this. I'll see if I can find it, and if I do I'll post a link. EDIT: http://www.mytractorforum.com/showthread.p...t=build+exhaust Not exactly what you were asking, but it may be of interest. :thumbs: Share this post Link to post Share on other sites
