I am working on a 84 small LTD wagon that is basicly a Fairmont that has a plugged cat converter,I got looking at it and there are two small converters one on each side right after the manifolds and one after they go togather. Not knowing what is plugged I was wondering if there was a offroad Y pipe available for the V6s,it looks like the Y pipe will have to come off so I can bust a hole through both small converters so I can get it to run long enough to see if there is anything causing them to plug and go from there. Before I do anything is there any way to tell which one is plugged.
