Thanks, although I do understand the environmental impact of removing the internals of a catalytic converter, and I do intend to replace it. What I'm concerned with is the mechanical impact of removing the internals, I'm trying to determine if this is the only problem or if there are more. As I said, this catalytic converter has four connections, two large (Inlet from engine, outlet to muffler) and two smaller connections about an inch in diameter on the sides of the catalytic converter. What is the purpose of these two additional pipes? Because there is no longer a back-pressure over the catalytic converter. Could this be the problem? Before any of this happened the engine idled smoothly now it hunts back and fourth a hundred or so RPM. The thing is, the last time I tried to get this corrected it cost me over $3,000.00, I drove 50 km for a camping trip and thankfully had CAA to tow me home.
