 Exhaust leak?

On my bike I've noticed a strange noise coming from under the pipes, just 2-3" after the head pipes with the muffler connection.
I've noticed some small holes there.
Are they holes to prevent water condensation into the pipes, or the previous owner of this bike tried to do something strange on them?
I'm going to build my own mufflers, but I'm curious to know if you also have this holes and some hot gas coming out from them.

Use some high temp RTV silicone in the muffler/head pipe connection. Just loosen the clamp, remove rear bracket, slide the muffler off. Then put a thin bead of silicone just inside the muffler right about where the slots are. Reassemble and let set, problem solved.

Like Kyle said, try the high-temp RTV sealant. The muffler pipe has slots in it, and mine didn't seat all the way on the header pipe. It made the "small holes" like you described. They shouldn't be there; just seal them up. By the way, I like the black/sky blue Speedmaster you have. Nice color scheme.  Will

Today I've found two stainless steel cones to build my own pipes. The beginning of the mufflers has to be conical or the pipe will look too artigianal.
Thanks for the color scheme. At first in picture I didn't like. But in front of the bike it is better than in the picture.

I'm going to resurrect this thread because I have a question about the high temp RTV silicone. When I was cleaning up my cylinder head I noticed some left-over goop around the exhaust ports. Can I assume that was this silicone? Do I need it or should I wait and see? I've got new copper gaskets.

New copper gaskets should do the trick. I have used the silicone on the pipe where the muffler clamps with good results. You could use a thin coat on old exhaust seals and re-use em (probably the case with yours)

I did both Wendys bike and mine with no silcone John,and have no leaks. You can use that super copper if you want, it won't hurt but I don't think you need it.

I'll probably try running without sealant and only add sealant if there's a leak.
