2004-2015 Nissan Titan Catalytic Converters

Most first-gen Titan owners only think about 2004-2015 Nissan Titan Catalytic Converters when the check engine light turns on and the diagnostic points to a P0420 or P0430 code — converter efficiency has fallen below threshold, and the options are replacement or a failed emissions test. Getting the right replacement spec installed correctly is what puts the truck back in compliance and clears the light for good.

 

Direct-fit replacement converters for the first-gen Titan bolt into the existing flange positions without any cutting or custom fabrication, which keeps the install accessible for owners doing their own work. High-flow catalytic converters are available for first-gen owners who want to clear the emissions requirement while reducing some of the exhaust restriction the factory converters introduce — they meet OBD-II efficiency thresholds while flowing better than the factory units at the RPM range where the V8 is working hard.

 

Catalytic converter replacement on the first-gen that actually clears the code and keeps the truck legal is what 2004-2015 Nissan Titan Catalytic Converters cover.
