Cel Delete Kit
Installing catless downpipes will trigger a check engine light (CEL) due to the absence of OEM catalysts. To eliminate the CEL without a tune, we offer a CEL Delete Kit featuring O2 sensor spacers that comply with vehicle’s emissions parameters, effectively removing the CEL.
Vehicles manufactured from 2019 onward are highly sensitive, and the Check Engine Light (CEL) may not always be eliminated. However, the modification may help delay its activation.
This is designed to be universal and generally speaking we cannot guarantee it will work. These are built to be adjustable. Email us if you get any codes.
