A quick and accurate way to determine a restricted exhaust system by measuring backpressure at an O2 sensor location.

In this video I use my home made lowpressure transducer along with the PicoScope featuring custom scales.

Looking at your backpressure from the driver's seat sure beats looking at a mechanical gauge hanging under the truck!

Enjoy!

P.S. Let me know in the comments if there is any interest in a customtailored pressure transducer kit, and if you want to see a video describing the custom kit and its capabilities :)
