Your entire exhaust systems purpose is to get the engine gas fumes from the engine to the outside air using many different types of exhaust pipes.
What other Nelson Aftermarket exhaust parts will I need?
Depending on your current exhaust system, you could need several nelson truck exhaust pipes to complete the job. If you are needing to find out what OEM exhaust pipe fits your truck, you will need to call the dealer for your truck in your area and provide them with your VIN#. We DO NOT have access to OEM VIN Lookup at this time.
How do I know what Type of Ends I need? ID or OD?
When purchasing Nelson Exhaust Components, please make sure that you are getting the right size and have the ends figured out 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 slides inside of the ID.
