How to Find the Diameter of an Exhaust Pipe in an Altima
Adding a custom exhaust to your car is a good way to gain horsepower and a more aggressive tone to the exhaust at the same time. You could go out and buy a bolt-on system for your Altima, but if you want to truly customize, youll have to step up and have an exhaust built for you. First, though, youll want to find out what size your Altimas exhaust tubing is. That way you have a baseline to use as you determine how much you want to go up.
Instructions
- 1
Lift the Altima using the jack and place it on jack stands at all four corners. Make sure there is enough room for you to crawl underneath the car.
2Locate the section of exhaust tubing that you want to measure. Open the calipers and place them over a straight section of exhaust tubing. Then tighten down the caliper until it contacts the exhaust all the way around.
3Read the dial or digital gauge on your caliper to find out the approximate diameter. Exhaust tubing sells in average sizes: 2.25 inches, 2.5 inches, 2.75 inches, and so on; there are no odd sizes. Round the number on your caliper down to the next quarter size down, and thats your exhaust tubing diameter.

How to Measure a Fuel Line Diameter
Determining the size of a fuel line in a vehicle or motorcycle is important prior to replacing it. The fuel line, along with the other parts of a fuel system, are responsible for delivering the fuel from the fuel cell into the carburetor. It is important to have the right size so the vehicle operates efficiently. The size of the fuel line is determined by the outside diameter. Completing the measurement is simple and takes relatively few tools. The same steps can be used to measure other types of tubing, such as those for brake lines.
Instructions

Uncover the fuel line so that it is visible and can be reached easily. Do not remove the fuel line or disconnect it.
2Place the top of a 1/4-inch wrench with an open end over the fuel line. Slide it caully over the line so that it fits snugly against the tubing. Read the wrenchs measurements to determine the diameter of the fuel line.
3Place a caliper over the fuel line if the wrench did not give an accurate reading. Calipers are used to measure distance between two sides of one object. Adjust the tips of the caliper to fit tightly on either side of the line. Remove the caliper. Place the tips on a ruler and read the measurement.
