BELEY Exhaust Back Pressure Tester Kit — 5-Foot Hose, 2.5-Inch Gauge, M12/M18 Adapters

Overview

The BELEY Exhaust Back Pressure Tester Kit is crafted for professionals, dealers, and DIY mechanics who want clear insights into exhaust flow. By measuring back pressure, you can spot signs of a restricted exhaust path, such as a clogged catalytic converter or a muffler that may be impacting performance and heat management. The goal is to provide practical data that informs when a service path should be considered, without promising perfect outcomes.

What makes it stand out

The kit pairs a precise 2.5 inch pressure gauge with PSI and Bar units, complemented by color-coded zones for quick, at-a-glance assessment. A protective rubber cover helps the gauge endure busy shop environments, while universal adapters with M12 and M18 threads broaden compatibility with many exhaust ports.

• 2.5 inch gauge with PSI and Bar scales and three-zone color bands
• Drop-resistant rubber housing for daily use in shop or field settings
• Adapters available for M12 and M18 threaded ports to fit a wide range of exhausts

Designed for real-world testing

A 57 inch heat and abrasion resistant silicone hose allows testing from the driver’s seat, adding flexibility when the vehicle is in position. The hose is built to endure high temperatures (up to 300 C) and wear, so testing can be more comfortable and persistent where needed.

• Five foot hose for flexible positioning during tests
• Thickened, heat resistant construction for durability
• Clear, immediate readings in both PSI and Bar

Notes for accuracy: the unit is factory calibrated for precision; if the pointer shifts during shipping, you can reset to zero manually without impacting performance.

Practical uses and benefits

This kit supports professionals, dealers, and DIY enthusiasts who want to verify exhaust flow and explore potential blockages. While outcomes vary by vehicle and condition, the tester offers a practical path to assess whether an exhaust restriction might be involved in symptoms like sluggish acceleration or overheating.

• Quick checks for back pressure issues before deciding on repairs
• Useful for evaluating improvements after muffler or converter work
• On-vehicle testing from the driver’s seat for convenient diagnostics

Contents and usage steps are straightforward, helping you stay organized and focused on accurate measurements.
