How do I choose the Type of Ends I need?

When purchasing Exhaust Components, please make sure that you are getting the right size and have the Ends figured correctly.

ID = Inside Diameter

OD = Outside Diameter

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.  The OD will fit inside of the ID.
