It has a real, miniature catalytic converter built into it, so don't risk using an extension alone because they frequently don't function.
Your ECU will be fooled into believing the original catalytic converter is still in place by this O2 cel fix with miniature cat. Your post-O2 sensor will detect higher temperatures and a larger flow of unburned fuel when you remove your catalytic converter.
Check engine lights (Cel, SES, DTC) will be triggered as a result, and the usual error codes are P0420 (Catalyst System Efficiency Below Threshold Bank 1) and/or P0430 P0420 - Catalyst System Efficiency Below Threshold Bank *For OFF ROAD use only).
Notes: Before making a buy, please compare the details.

What causes the CEL on?
There are many aspects to cause the CEL on, one aspect is catalytic problem.
And our CEL eliminator is one kind of small catalytic converter in front of the O2 sensor, so if your real catalytic converter is broken, the CEL eliminator can help you to reduce the toxic gas.
But sometimes, the CEL alert is caused by O2 sensor problem. For example the O2 sensor is too sensitive, the CEL will still on after you load the eliminator. And still it will cause more Code error!
So our CEL eliminator (someone call it Mini cat) can not solve all the problem on CEL alert.
It can only solve one of the P0420 code--faulty catalytic converter (most common)
