Installation Notes and Tips

Confirm inlet and outlet diameter, offset configuration, and overall length before installation. This muffler uses pipe connections and is not reversible or tunable, so orientation matters during exhaust system replacement. Verify vehicle-specific fitment for your Dodge Ram van or Dodge B1500 application before ordering. Walker 21373 is a direct-fit style replacement for select 1998-2003 Dodge Ram van and Dodge B1500 exhaust systems.
