What other exhaust parts will I need?
Depending on your current exhaust system, you could need several truck pipes to complete the job. If you are needing to find out what OEM pipe fits your truck, It is best to call a Dealer in your area and provide them with your VIN#. We do NOT have access to OEM VIN Lookup at this time.
Your entire exhaust systems purpose is to get the engine gas fumes from the engine to the outside air using many different types of pipes.
Depending on your overall system design, the exhaust gas will flow through a wide array of exhaust parts below:
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.
