Messico Pipe cracked!

[pbspecial]

I have a 2003 GasGas 250 with a Messico pipe that only has about 10 hours on it (the pipe), it has never been hit and has always had an eline carbon guard. I noticed this morning when I went to start it that it was blowing some smoke from behind the pipe guard. I rode it and after cleaning it this evening, I removed the guard to find a hairline crack in it about two inches long!

The crack is right where the pipe makes the tight bend off of the manifold. Can these nickel pipes be welded? It looks like it would just need a good bead put down the length t of the crack. Any thoughts? Sure would be nice to pay someone a few bucks to weld it rather than shelling out another 200 plus for a new pipe...

Thanks
