The best way to check for a stopped up exhaust/catalytic converter, or any other exhaust restriction. Is to put a vacuum gauge on your engine and run the RPM'S up to about 2000 RPM'S. If the exhaust has any restriction at all, the gauge will go from reading vacuum to reading pressure as the RPM'S go up.
