Exhaust Back Pressure Test Kit Catalytic Converter Tester

An exhaust back pressure test kit used to check for restrictions in the exhaust system by connecting through the oxygen sensor port. It allows pressure readings to be taken when investigating suspected catalytic converter faults or other exhaust flow problems.

Used for vehicle diagnostics, servicing and fault-finding, this kit helps when a car is showing signs of poor performance, blocked exhaust flow or suspected converter restriction. It can also be used during test drive conditions, which is useful when faults appear under load rather than only at idle. Suitable for garage work, workshop use and more involved home vehicle maintenance where accurate exhaust pressure checks are needed.

The supplied gauge reads from 0 to 20psi, giving a clear operating range for exhaust back pressure testing. A 300cm connection hose gives extra reach when working around the vehicle and is fitted with a heat protection jacket to suit use near hot exhaust components. Connecting through the O2 sensor port gives a straightforward way to carry out checks without unnecessary dismantling, which is useful for regular diagnostic work and repeat testing when tracking intermittent faults.
