Includes Dynomax muffler. The primary diameter is 1 3/4". Silver ceramic coated. Long collector. Includes welded bung and plug for fuel/air probe. This is a standard sedan configuration. The muffler has the welded hanger for the sedan. Minor bumps and scratches from the racing activity, but overall in very good condition. You need a big motor to take full advantage of this header system. The first $125 takes it.
