Hi all,
I have an old suburu robin 5hp engine that needs a new muffler as the current one is rusted and has a huge secton missing out the bottom.
Now it got me thinking, it's a fairly simple design, I would be able to get away with a 3" bit of pipe for the main barrel, but i'm not sure what to do about the internals? Ideally I would like to keep it running fairly quiet.
Anyone done something like this before? If you have any photos or links please post up.
Thanks
