Step 3-Use the Caliper

Once you have located the exhaust pipe that you want to measure, use the calliper. To do this, open the calliper and position it straight into the mouth of the exhaust tubing. Next, close the callipers until it is in full contact with the inside surface of the exhaust pipe.

Step 4- Read the Measurements

Read the measurements. Doing this depends on the type of callipers that you are using. There are callipers with a digital or a dial gauge. Your exhaust tubing is the measurement in your gauge rounded up to the next quarter.
