Did you check to see what the code is for? The Stickies has a list of DTCs.
Everyone with aftermarket headers will get the P0420 and P0430 DTCs unless they do something with their secondary O2 sensors because you are removing both pre-cats. You need to either bung the secondaries behind the main cat or simulate them. There is more information on this in the Header Sticky.
