Crown Automotive 641878 Muffler for 45-71 Jeep CJ Series with 4-Cylinder Engine

Having the correct equipment for your Jeep is vital to keeping systems running as designed. The Crown Automotive Muffler is a direct replacement for the 4-cylinder F-head and L-head engines used until the early 70's. This muffler is made to fit into the original exhaust system without modification, look like the original equipment and maintain the compression.
