Default Re: Muffler broke while riding

Depending on the age of your original muffler, it might not have been a catalytic converter type and the new one is. There could be more restriction with the cat muffler. Compare them and let us know what you find.

Running a 2 stroke engine without some back pressure (no muffler) can cause an over lean condition that might have damaged your piston and cylinder walls resulting in a loss of compression. That would explain the decrease in power.
