In general, the bigger the exit pipe, the louder the exhaust will be. I used 2.25" which I think is about the minimum for a 20B.

I have fabricated my exhaust manifold/tangential muffler for my 20b. All I have left is to fit and weld the exhaust pipe. I would like opinions on the size the exhaust pipe should be. This is in a pusher application (Velocity) with a relatively short run from the muffler to the exit point. Similar installation to Al G.
Thanks,
