I did some searching on here but did not find exactly what I was looking for. I am pulling a code from my converters. I want to empty the 3rd cat but no one carries the gaskets for it that I can find. Does anyone know of a gasket that will fit it, or where can I buy a pre made pipe to replace the cat? I saw a post mentioning one for $130 but it did not say where to get it from. Also could installing aftermarket mufflers have made it pull this code (I cannot imagine that but you never know). Thanks..
