All suggestions so far are good, take your pick.
Here is mine: have a muffler shop make a 90deg. sweep bend of minimum radius (usually 8" for pipe as big as 2.375" which is the actual O.D. of the exhaust pipe stack) this should be made from 2.375 O.D. muffler pipe. Next have one end expanded to fit the O.D. of the exh. pipe for a depth of 2-1/2".

I would use a very short automotive oval muffler, Or if bucks are not an issue, a welded stainless oval auto muffler. I would aim the muffler toward the driver with the off set clearing the air intake. then use an additional 90 bend to direc the exhaust down and to the left. I would build a support for the end to eliminate breakage of the manifold, or stressing of the threads on the existing pipe (usually an issue at some point anyway) my stout support {maybe chanel style fence post material} would bolt only to the frame rail, or other existing holes (never to the hood, or other sheet metal). It would be off set to clear all other parts and sheetmetal to stop rattles and wear.

My design deflects limbs up and off of the air cleaner, and catches fewer of them. It also will be far enough off of the hood to avoid scorching, and last it will be very quiet(which I and my neighbors like). There is also no need for a rain cap. Good luck with the project, let me know your solution. Jim Nicholson
