Engineered to identify restrictions in catalytic converters and mufflers, this exhaust back pressure kit compares pressure readings ahead of and behind suspected blockages. The 0–15 psi gauge connects to 8 feet (2.4 m) of heat-resistant silicone-tipped hose, providing the reach and thermal protection necessary for testing during operation. Technicians can interface with the exhaust system using the included 12/18 mm oxygen sensor port adapter or by installing the provided self-tapping bolts into a punched hole.
