For the State of California our Exhaust Products are not C.A.R.B.
Our Exhaust products have no guarantees about passing emissions in your state.
Our High Performance Exhaust with sports catalytic converters are built and meant for off-road purposes.
Our Exhaust Products “Lifetime Warranty” does not cover catalytic converter error codes.
Please note that when installing High Performance Catalytic Converters there is a possibility that you may get a “Check Engine Light” for Catalytic Converter Inefficiency or other Catalytic Converter related error codes. This may or may not happen, this is due to lowering the Cell Count of the catalytic cartridge, in other words we need to work with the same surface area with a lower cell count, most OEM Catalytic Converters will have 600 to 800 Cells per square inch, High Performance Catalytic Converters are only 200 Cells per square inch. If you get a check engine light it’s not because the product is defective but it’s the ECU picking up the difference and relating those error messages.
There are several ways to deal with this.
Most Efficient is the Flash the ECU with performance software, make sure to tell your tuner that you have 200 Cell Cats. This is the most expensive and most efficient.
Use 02 Bungs, many have been successful by using 02 Bungs however this is not 100% Bullet Proof.
Purchase OBD2 Scanner, read your codes and erase them. For those of you who are not annoyed by the use of a scanner on a weekly basis this is the cheapest solution.
