Designed to pinpoint exhaust blockages through oxygen sensor ports, exhaust pipes, or air injection systems, this 3-way tester provides comprehensive diagnostics for catalytic converters and mufflers. The dual-scale gauge includes multi-colored bands for quick reference at idle and 2500 RPM, while a 6' (1.8 m) hose enables the technician to observe pressure changes from the driver’s seat. For broad compatibility, the kit includes M12 and M18 threaded adapters along with a flange and gasket for specialized sensor types.
