Baffles are found inside the muffler. They are used to silence the noise an engine makes while running.
Because of condensation the inside of your muffler, the muffler will begin to deteriorate (rust) over time from the inside. This can and will cause holes in the muffler. Along with the hole (s) the internal structure of the muffler will eventually break apart and plug the muffler, preventing the exhaust gas and the pressure from the engine from exiting the vehicle. This will cause what is called "back pressure" on the engine, causing it to lose power. Extreme example would be "you push the gas pedal to the floor but the car will not go more the 25 miles per hour". I would recommend you have you muffler replace. That should solve your problem.
