Holes in my dirt bikes exhaust pipe, will it effect performance?

I have a 1989 CR125 two stroke. My exhaust pipe has what I assume is a metal skid plate on the exhaust. It is riveted into the exhaust and all the rivets have fallen out allowing exhaust to come out of about 4 or 5 holes. The holes are located on the bottom of the pipe right as it comes out of the head to go toward the back of the bike.

Will this effect performance?
How can I seal the holes permanently?
I can't, I don't have a machine for it and I don't know how.
