Identified the muffler as being rusted out at the tailpipe as it goes into the muffler. Ordered the part from Gowesty as it is a vintage Volkswagen Camper. When it came in, had it installed in 1 day. When Chris pulled the muffler he found out the catalytic converters insides were starting to deteriorate and would need replacing. He really goes above and beyond on fixing things correctly. Am looking forward to a more silent muffler and hopefully not polluting the environment as much. Thanks Chris.
