Tuner Required for Installation: Installing a Dodge Ram 5.9 Disele delete pipe requires more than just swapping out hardware.

A tuner is required to prevent any check engine light or diagnostic trouble codes from setting. ---tab Fitment--- 1998.5-2002 Dodge 2500/3500 5.9L Diesel Note: Muffler Delete.
