Steve,
My mufflers do not have drain holes. Are drain holes needed if the bike is kept in a garage and never ridden in the rain?

If a bike is run for a short period there is moisture in the muffler. Shut it off then and that moisture settles in the muffler, hence the drain hole.
After it has been run hot for a while ( full op. temp.) the moisture gets dissipated and inside the muffler is dry.
Also, moving it from a cool environment into warm humid air cause condensation. Think of a cold beer glass on a humid day.
I think a drain hole at the lowest point is a good idea.
(Just my humble opinion.)

I bought a set of DSS pattern mufflers 6-8 years ago and they had drain holes on the undersides.

Interesting. Phil, Our sets must be part of a new run. David told me a few months ago he didnt know when he would have any.

I recommend you drill a hole for the moisture to exit or the moisture will gather and become caustic and make it's own hole which you won't be pleased with!. ...............lm

Thanks LM
I am going to just wrap my set back up and put them away for another project. I have some coming from Overlander that I am going to use. Phil, I'm sorry for hijacking your thread, I'll get off now. Thank again for the pics and information.
