Thexton Back Pressure Test Kit (389)

The Thexton Back Pressure Test Kit (389) is a vital tool for automotive professionals and DIY mechanics seeking to accurately diagnose exhaust system issues. A vehicle’s exhaust system is critical for both performance and emissions control, and blockages—such as a clogged catalytic converter, restricted muffler, or collapsed pipe—can lead to power loss, reduced fuel economy, and other engine performance problems. This specialized adapter kit provides a precise and reliable method for measuring back pressure, allowing technicians to pinpoint the exact location of a restriction without extensive disassembly. Used with a separate 0-15 PSI pressure gauge, it quickly determines if engine performance issues are caused by exhaust blockages, saving valuable diagnostic time and ensuring the vehicle operates at optimal performance.

KEY FEATURES AND BENEFITS:

• Accurate Diagnosis: Enables precise measurement of exhaust back pressure to identify blockages.
• Time-Saving: Quickly locates restricted exhaust components, reducing diagnostic time.
• Targeted Troubleshooting: Pinpoints the exact location of a restriction, such as a clogged catalytic converter or muffler.
• Essential Components Included: Comes with a hole punch for air hammer use and a self-tapping bolt to plug the test hole after use.
• Versatile Application: Designed for use with a standard 0-15 PSI pressure gauge, adding flexibility to your toolset.

SPECIFICATIONS:

• Product Model: 389
• Included in Product: Hole Punch, Test Adapter, 5/16″ x 1/2″ Self-Tapping Bolt

HOW TO USE:

• Preparation: Locate a suitable test point on the exhaust pipe before the suspected restriction.
• Create an Opening: Use the included hole punch and an air hammer to create a small hole in the exhaust pipe at the chosen test point.
• Connect the Adapter: Securely install the test adapter into the hole.
• Attach the Gauge: Connect a separate 0-15 PSI pressure gauge to the test adapter.
• Run the Test: Start the engine and check pressure readings at idle and under slight acceleration to measure back pressure.
• Seal the Hole: After testing, remove the adapter and use the provided 5/16″ x 1/2″ self-tapping bolt to securely plug the hole.
