Diagnosing a Clogged or Partially Restricted Exhaust

Diagnosing a Clogged or Partially Restricted Exhaust
This involves drilling a small hole {typically 1/8-inch o.d. maximum} in the exhaust pipe ahead of the suspected part {catalytic converter or muffler}. Insert a probe connected to a pressure gauge that can read positive pressure {a two-way vacuum gauge works well} into this hole. Bring engine rpm up to a cruise speed {2500-3000 rpm} and note the pressure indicated. Readings on the order of 5 inches are considered acceptable, but if they reach the range of 10-15 inches, chances are good an abnormal restriction exists. When the test is complete, a small pipe plug or self-tapping metal screw will plug the hole, especially when used in conjunction with some form of high temperature epoxy.
