those rubber expansion plugs from lowes work killer. i think they are used to plug a pipe while you work on it, its a rubber plug with a big wingnut on top

You can use the rubber freeze plugs that you get from the auto parts store to.

I use a intertube and a piece of aluminum. Mine works great but a plug would probably work better

for the exhaust, use a expansion plug. will give you the best seal.
mine didn't have the wing nut, but had a 12mm nut that you had to tighten with a wrench.

I asked this question a while back. EVERYONE says get a expansion plug, but NO ONE gives a size! They come in many sizes and the correct would be great.

Yea, Yea, I know go measure, but if you're going to give advice at least make it complete.

A steel plate and a piece of inner tube worked great for me. I just used the exhaust flange as a pattern.
