How to Fix Leak in Sea Doo Jet Ski, Fix Cracked Exhaust pipe in Sea Doo 1996 GSX

I had a Leak in my 1996 GSX Seadoo and did not know where it was coming from, so i went step by step to figure out the problem then took off part that had a crack in it, had it welded for $20 put it back together, retested for leak and was good to go.
