Do I need new gaskets or O2 sensor bungs when I install this?

Yes—grab new flange gaskets before you start. The O2 sensor ports are factory-standard size, so your existing sensors thread in as-is, but fresh gaskets prevent exhaust leaks at the manifold connection.

Will this pass emissions testing?

This converter is emissions-compliant and designed to restore catalytic performance on V6 engines. If your vehicle is already registered and tested, this will meet standard requirements—just confirm your local regulations with your testing station.

What tools do I need to swap this out?

Basic hand tools—socket set, wrenches, and jack/ramps. Remove the heat shield, unbolt the old unit at the manifold and rear hangers, slide the new one in, and torque the bolts. Refer to your vehicle's service manual for torque specs and sequence.
