Depending on your current exhaust system, you could need several truck pipes to complete the job.
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.
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.
Dont forget your clamps to complete the job.  Most any clamp will work, it just needs to be the same size diameter as the exhaust pipe you are purchasing.
