Exhaust Noise Re-visited
Both my '92 and '94 have identical exhaust noises. I concentrated on the '92 because iut also had a leak. I have replaced the leaky pipe (left front cat') and all new gaskets. I have NO leaks now. I also relaced or repaired all of the heat shields so they are not rattling.
I have heard that there is an internal baffle that breaks loose and can cause this noise. Noise occurs at part throttle, mainly light acceleration. It goes away at idle and half + throttle.Noise is definitely near center of car.
I have listened with a hose and can not be sure where noise is coming from, definitely internal. Does this baffle problem occur in the Y-shaped, 2-into-1 cat' or in the first silencer just behind it?
