Perhaps before I get involved with a huge project like replacing a transmission and designing/building a backhoe (easily hundreds of hours of labor and well more than $1000 in materials) it would be wise to actually learn how to weld. Fool that I am.
So, to start small, I would like to replace the stock mufflers with a big, quiet muffer from a car or truck. As it is now, I have to wear ear plugs while this one is running. I think one of the exhaust pipes has a split in the seam, I can see heat stains where it is leaking.
I have been trying to calculate the exhaust flow CFM, and will have to match it with something from a car. I imagine something from a little toyota or an old GEO, something that has less than 2 liters... Either that, or a motorcycle exhaust, maybe from an old Honda Nighthawk, like a 500 or 650....
Have any of you guys had luck with such a project? Any ideas where to start? I would run the two exhaust ports into 1 pipe, and then turn it 90 degrees and attach the muffler like a stack similar to the one on Jim's 782. Only instead of being cool like Jim's, it would look..... different.
The muffler will have to be big enough to silence the exhaust, but also to provide roughly the same amount of back pressure as the stock exhaust pipes. It does not strike me as an easy task, as I am not a math guy, more of a hands-on, trial and error type of person.
