review this for your dc header

Resetting the ECU wont help if it is the CAT failure code. You will need to use the antifouler or similar fix for it.

As mentioned, find out what code you have first. If you are modding your car, you should own in the very least a code reader, if not a diagnostic tool. And start learning a little about the various codes and how stuff works together. Best investment you can make.

Other than that , search, this has been covered a few places so there is a ton of info on it.
