Muffler Corrosion — its cause and control

ACID CONDENSATE and its effect on mufflers is being controlled to an acceptable limit by a combination of three methods:

1. 1.
   Use of hot-dipped zinc.
2. 2.
   Use of aluminized steel.
3. 3.
   Improved design.

The author describes the materials tests and temperature tests on single and dual exhaust systems, which are used to evaluate various muffler designs. He also describes the use of condensate drainage.
