Hole in muffler

Hey, does anyone know how to fix a hole in a muffler? I have this popping sound from the muffler and im pretty sure its a hole. Is there a fix for this? I have to pass inspection next week : ) Thanks

The only thing I can think of is to bring it to a muffler shop and get them to weld something to the hole

You think I'm better off getting a new muffler? (I'm running stock:eek: ) If so which do u think is a good one, and quiet too... i hate loud dirt-bike sound. : P Thanks

good + quiet = Thermal R&D
