Phillip Posted February 15, 2004 Report Share Posted February 15, 2004 I have been noticing what appears to be exhaust noise under the hood. I can't find any leaks in the pipe system, although it is very difficult to get near the rear manifold. Is it possible that the noise is a result of a plugged cat? I have had performance issues lately have been unsuccessful in diagnosing any problems with the ignition, fuel or vacuum systems. If it is not the cat, then I assume the noise id coming from the exhaust manifold. Any thoughts? Thanks. Link to comment Share on other sites More sharing options...
