FAQ:

Q: What do I need to measure exhaust backpressure?

A: The first thing you need is a pressure gauge that can read up to about 20psi. They sell these at auto parts stores and many can read vacuum as well. For exhaust back pressure, I prefer mechanical gauges because they’re generally cheaper to replace and less delicate.

Q: Is there a performance gain from reducing exhaust backpressure?

A: Most enthusiasts know that reducing backpressure in the exhaust system will typically yield a performance gain. However, there is much speculation about what exactly makes a big difference and what does not.

Q: How big is the hose for a pressure gauge?

A: The gauge is 1/4″ pipe and the hose is 1/8″ pipe. You’ll have to buy adapters to connect them together. Otherwise it works fine. It only fits one size sensor so you might need an adapter there also. I was lucky.

Q: What’s the best way to measure back pressure?

A: Now back to that O2 bung thing. The easiest way to measure back pressure is to find one of the secondary O2 sensors, unscrew it, zip tie it out of the way (or remove from the car), and temporarily plumb in your fitting to take a measurement.
