Exhaust System Components - 2.3L: Muffler

WARNING: This page is about a different car, the 2005 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.

Mufflers are usually treated during manufacturing with an anti-corrosive coating agent to increase the life of the product. The muffler reduces the level of noise produced by the engine, and it also reduces the noise produced by the exhaust gases as they travel from the catalytic converter to the atmosphere.
