When fitting sports cats there is a possibility, depending on how sensitive the ECU is, that the 200 cell catalytic converters can show a catalyst inefficiency fault code.

The reduced number of cells means a smaller surface area for the conversion of Carbon Monoxide to Carbon Dioxide which the diagnostic lambda sensor can see as inefficient and bring on the MIL lamp or worse send the vehicle into limp mode.

To keep your vehicle running at its best after fitting high flow sports cats we can fit inline micro cats, unlike the lambda spacers many companies offer, these are real catalytic converters on a small scale.

To be fitted between the exhaust and the second OBD lambda or oxygen sensor, a small amount of exhaust gas that has been converted by the sports cats already is passed through the micro cats to undergo a further conversion of harmful gasses.

This tells the sensor that the cats are working above the conversion threshold for safe operation.

1. A worn-out oxygen sensor leads to excessive gasoline consumption, elevated exhaust emissions, and accelerated catalytic converter damage. Our Oxygen Sensor Replacement Kit addresses these issues, optimizing fuel efficiency and reducing emissions for a cleaner engine.
2. In regions with emission-regulating vehicle inspection programs, a faulty Check Engine Light (CEL) and O2 sensor can result in inspection failure. Our kit ensures compliance, allowing your vehicle to pass inspections seamlessly.
3. Our kit provides a practical solution to common fault codes such as P0420, P0042, and P0430, ensuring your vehicle operates smoothly and minimizing the risk of more significant problems.

Get Rid Of That Cel...REMOVE P0420, P0430 Error Codes.

This O2 cel fix actually has a miniature catalytic converter built inside and will help get rid of that annoying check engine light you get after modifying your exhaust or removing your catalytic converter, and sometimes even when installing a highflow catalytic converter.

This O2 cel fix with miniature cat will trick your ECU into thinking the stock catalytic converter is still installed. When you remove your catalytic converter, your post O2 sensor will see higher temperatures and greater flow of unburnt fuel.

As a result this will throw check engine lights (Cel, SES, DTC) typically the error codes will be P0420 (Catalyst System Efficiency Below Threshold Bank 1) and/or P0430 P0420 - Catalyst System Efficiency Below Threshold Bank 2).
