Our take on the A-Premium Rear Catalytic Converter Kit Direct-Fit Compatible with Nissan Altima 2007-2018 3.5L, EPA Compliant

This is a direct-fit rear catalytic converter for the 2007-2018 Nissan Altima 3.5L V6. It uses a three-bolt welded flange at the inlet and a two-bolt welded flange at the outlet, and the body is stainless steel. It is EPA compliant for federal emissions, so it is not legal for sale or use in California, New York, Colorado or Maine. It suits owners replacing a failed or rusted rear converter who want a bolt-on part rather than a universal weld-in unit. Mounting hardware is not included, so you will need to reuse or buy gaskets and bolts. As a budget aftermarket part it undercuts OEM converters, but it carries only a one-year warranty and no CARB approval, so it is not an option for emissions-restricted states.

Questions and answers

Will this fit my Altima?
It is listed for the 2007-2018 Nissan Altima with the 3.5L V6 only. It is the rear converter, not the front one. Check your engine and position before ordering.
Is it legal in California or New York?
No. It is EPA compliant for federal emissions only and is restricted in CA, NY, CO and ME. Shoppers in those states need a CARB-approved converter.
Does it come with gaskets and bolts?
No. Mounting hardware is not included. You will need gaskets and bolts for the three-bolt inlet and two-bolt outlet flanges.
Is it a direct fit or does it need welding?
It is a direct fit with welded flanges at both ends, so it bolts to the existing exhaust. No cutting or welding is needed if the old unit comes off cleanly.
What is the warranty?
A-Premium lists a one-year warranty on this converter. Keep your purchase record in case you need to claim it.
Will it fix a check engine light for a bad converter?
If the rear converter is the cause, replacing it can clear the P0420 code. Have the code read first, since oxygen sensors and exhaust leaks cause the same light.
Where is the A-Premium Rear Catalytic Converter Kit Direct-Fit Compatible with Nissan Altima 2007-2018 3.5L, EPA Compliant cheapest?
