Product Details


When a high-flow catalytic converter or test pipe is used on a late model car it's guaranteed that CEL (Check Engine Light) will come on. This CEL is caused by a fault code that indicates an inefficient catalytic converter.

Our CEL eliminator is CNC machined in-house from high quality cold roll steel for a long-lasting effective performance.

Install this spacer on your REAR (downstream, post-cat) oxygen sensor to effectively remove the code for catalyst efficiency. This is recommended for vehicles that do NOT have "stage 2" software.
This product is not intended to and will not provide emissions compliance. FOR OFF-ROAD USE ONLY!
Emissions laws vary by state and by province. Check local and federal laws before modifying your exhaust system.
Emissions compliance is the sole responsibility of the vehicles owner.

This is a universal product that works on variety of vehicles, however it is not effective on some cars.
