How To Measure Your Exhaust & Choose Top Stacks

Making your truck look good means you have to add on a lot of aftermarket parts. Most trucks don’t come with all the fancy chrome accessories or even the highest quality parts. Replacing parts and adding some customization can make your truck look and operate better. One common change drivers make is to add top stacks. To do this, you first need to learn how to measure your exhaust, and then you can start looking at the  best semi truck exhaust stacks.

Measuring Your Exhaust

You need to measure the pipe on your exhaust so you can properly fit the top stacks. You
will need two measurements: internal and external diameter. The names pretty much explain what each measurement is. The internal diameter includes just the inside of the pipe, which gives you the measurement for the other pipe you would fit into it. The external diameter gives you the measurement for another pipe that would fit around it and measures the pipe itself. Here’s a simple guide:

  • Internal – measure the pipe opening from edge to edge, not including the pipe, just measuring the hole
  • External – measure the pipe opening from edge to edge, including the pipe

Make sure to measure all pipes as sizes may vary along system. Depending on what you will adding or changing, you may need different measurements. Also, measure the internal and external diameters for both inlet and outlet pipes. If your measurements are correct, new parts should fit securely when attached.

Choosing Top Stacks

Now that you have the measurements you need, you can choose your semi truck exhaust parts. Making this choice may actually be more difficult than taking the measurements. There are a lot of options and variances between each option. Make sure you consider the overall look you want to achieve, along with the current look of your truck. After all, if you are adding on new parts gradually, you want some cohesion between old and new so your truck still looks good throughout the process.
