I wish I took a pic to better show my current exhaust , but I imagine it’s a fairly typical setup - black iron pipe attached to a flange on the manifold, goes straight up 12 inches or so, curves back down 180 degrees, drops a few inches before attachment point for cooling water, and then large ( 2 5/8” I believe) exhaust hose off to the muffler.

The iron is in pretty rough shape - rusting away to the point that big chunks are flaking off. So I need to get this taken care of. Seems like it would be easy enough to build with off the shelf Home Depot parts - but not sure on the flange which connect to the manifold. Moyer sells a flange for $70, do I start with that, and then just buy the pipe I need? How do I seal the threads? Is it really necessary to wrap the exhaust? The old stuff is coming off all over the motor, would rather not replace.

Has anyone built, or purchased, an exhaust who can give me some pointers? Thanks.
