About Measure Exhaust Pipe

Measuring  exhaust pipe diameter is a critical step in the process of upgrading or maintaining your vehicle’s exhaust system. Correctly measuring diameter of the exhaust pipe will allow for easy compatibility with other exhaust system components, greatly reduce noise, and save you time and hassle in subsequent exhaust system installations. This blog will introduce about measuring exhaust pipe, making it easy to learn and master.

What We Need to Measure About Exhaust Pipe ?

Inlet Diameter and Outlet Diameter

Engine’s outlet directly connected to the exhaust pipe is exhaust pipe inlet diameter, which smoothly receives the exhaust gases from the engine.
The diameter of the exhaust pipe from which the exhaust gases are discharged is the exhaust pipe outlet.
The exhaust pipe has a certain resistance when discharging exhaust gases, so exhaust pipe outlet diameter is generally smaller than exhaust pipe inlet diameter.

Inner Diameter and Outer Diameter

For the diameter of the exhaust pipe, the dimensions are Outer Diameter (OD) and Inner Diameter (ID).
Outer diameter is the diameter from the outer edge to the other outer edge, including the thickness of the exhaust pipe, the inner diameter without the thickness of the exhaust pipe.
Most exhaust pipes are generally measured outer diameter.

Preparation before Measuring Exhaust Pipe

• Cooling: In order to ensure the safety of the measurement process, the exhaust system should be completely cooled down before the measurement.
• Cleaning: In order to measure the exhaust accurately, clean the exhaust inlet and outlet of dirt, rust, oxides, etc. before measuring.
• Preparation of measuring tools: Vernier calipers, bore gauge, tape measure etc

How to Measure Diameter of Exhaust Pipe?

1. Straight-Cut Exhaust Pipe: Use calipers to measure the centre of the pipe from outside to outside directly, and take the average value of 3 measurements.
2. Oblique Cut Exhaust Pipe: With a soft ruler or thin rope + ruler combination, tightly wound pipe at the maximum circumference, and then and the ruler compared to the size of the exhaust pipe, the circumference of the exhaust pipe, divided by 3.14, you can get the diameter of the exhaust pipe.

Standard Exhaust Pipe Sizes

After measuring the diameter of the exhaust pipe, we need to compare standard exhaust pipe size.
For example, the common standard titanium pipe sizes are 1 inch titanium tube, 1.5 inch titanium tube, 1.75 inch titanium tube, 2 inch titanium tubing, 2.5 inch titanium tubing, 3 inch titanium pipe, 4 inch titanium pipe etc.
Of course, the exhaust pipe diameter and the engine capacity is also a great relationship, large engine capacity needs to match the large diameter exhaust pipe, and vice versa small exhaust connected to the small exhaust pipe diameter.

Conclusion

If you read the above blog carefully, you can confidently measure your vehicle’s exhaust pipe size,no matter any material of the exhaust pipe. THT is a professional titanium supplier, we can provide different sizes of titanium exhaust pipes, titanium elbows, titanium U-bolts, titanium clamps and other titanium connecting parts for you to connect your exhaust system.
