I know this topic probably has been made MANY times, but I just need some clarification. I installed my DC Race header on my Si coupe, and the CEL came on after install. I don't HONESTLY believe a defouler is going to do the job.

I looked up and found this: Blox CEL Eliminator Adaptor

This will really do the job?? Any other options I can do?:wigglesmiley:

Theres nothing for the o2 sensor to screw into on this one you sent a link for...

I honestly dont understand how a defouler is going to fix this issue. Do you know any cheaper defoulers???

I have a Strup defouler on my Strup header and it never successfully eliminated the CEL that comes with removing the catalytic converter. The only surefire way to prevent CELs with a race header is with FlashPro. Defoulers aren't guaranteed to work.
