    The best way is to get the dealer nearest to you to run you a VIN report that breaks down all of your options. However, I believe the 2003 models only used the h. o. Cummins with the manual transmission.

    The manual trans has the HO 305 HP 3. 5 exhaust See if U can find a 04. 5 or newer the exhaust is 4″ delete the cat.
