catalytic convertors covered 8yrs/ 80,000 miles

Extended warranties by security plus (nissan extended) do not cover catalytic convertors.
Its obvious you are within 8years, its the 80,000 miles if you are past that point or not.

Powertrain warranty is 5yr/ 60,000mi

The STILLEN Y-Pipe may not resolve your problem if your catalytic convertor is bad.

If you have done the P0420/P0430 reprogramming, you may need to replace both rear oxygen sensors on vehicle before your put on the STILLEN Y-Pipe.

Your 'self learn ecu' will try to compensate for the errors in the oxygen sensors, and cause your car to run real rich and you will lose fuel economy and power.
