Our take on the Catco 5309 Direct Fit Catalytic Converter and Pipe Assembly

The Catco 5309 is a direct-fit catalytic converter and pipe assembly for vehicles with the 3.6L V6. It bolts to the factory flange points and uses OEM-style sensor ports, so no cutting or welding is needed. It is built from stainless steel and meets federal EPA emissions standards, but it is not legal for sale or use in California or other CARB states. It suits owners replacing a failed or rusted converter on an out-of-warranty vehicle who want a bolt-on part rather than a universal weld-in unit.

Questions and answers

Will this fit my 3.6L V6 vehicle?
It is built for the specific 3.6L V6 applications Catco lists for part 5309. Check your model year and engine against that list before ordering, since it is not a universal part.
Is it legal in California?
No. It meets federal EPA standards only and is not legal for sale or use in California or other states that follow CARB rules.
Do I need to weld it?
No. It is a direct-fit assembly that bolts to the factory flange and hanger points. You reuse the factory O2 sensors in the OEM-style ports.
Are gaskets included?
No. The assembly ships without gaskets, so plan to buy the correct flange gaskets and any rusted hardware separately.
Will it clear my check-engine light?
If the code was caused by a failed converter, a properly installed replacement should clear it. Have the code read first, since O2 sensor or misfire faults can trigger the same light.
How does it compare with a universal converter?
A universal unit is cheaper but needs cutting, welding and custom sensor placement. This one bolts on with factory-style ports, which saves labor if you are doing it yourself.
