Drilling Exhaust Drain Relief Holes

[Guest]

I just picked up a nice original exhaust system from my '83 GS1100E and since I drive to work for only a short distance, I don't want this set to rust out due to not enough heat building up to allow it to burn off.

Would anyone recommend drilling drain holes in the bottom of the tubes to allow the condensation to escape rather than let it 'pool' in the pipes?

I seem to recall that the older Hondas had this drain provision in their factory systems.

If you drill holes in the system you will probably most defiantly in up with a popping on deceleration don't do it

I thought original GS exhaust systems already had these holes -- a question that pops up here regularly is "what the heck are these little holes?"

Mine (both the L and the G) came with the drain holes in them.

My 79 has them too.

They rust shut most of the time. Id take them off and save them , thats what I did with my 80 GS1100E

Wow, I'm tripping out on this one. Do you keep the holes in a jar or something?

If you don't ride long enough to get the entire system up to operating temperature, it will rust from the inside. Holes or no holes.

I've got a quart jar full of exhaust holes, we end up with those in all our mufflers here in the rust belt.... That's in addition to the engineered drain holes They are rather difficult to see once they're in the jar though, and sometimes it can be mistaken for an empty jar.

Reminds me of a load I had to carry occasionally when I was driving truck.

It wa a very dangerous mixed load of post holes, sailboat fuel and dispatcher brains.

If were talking about holes on the mufflers, they only perforate the outside skin of the muffler so that any condensation that builds up in between the baffling and the outside skin can drip out/evaporate off & minimise rusting.
