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.
