How do I choose the Type of Ends I need?

When purchasing our Truck Exhaust Products, please make sure that you are getting the Correct Exhaust Diameter that matches your truck, also make sure to have the Ends of the pipes figured out correctly to match up together.

• ID = Inside Diameter or sometimes referred to as expanded or slotted
• OD = Outside Diameter is also known as plain ends or smooth.

You can think of the pipe with an ID end as being the Female end of the Pipe, and the OD ended pipe being the Male.

So, if you have a 5" OD pipe and need to fit it up to another pipe, you will need a 5" ID.  The OD will slide into the ID.
