Depending on the programmer you can turn off your rear 02's I think. High flows should not cause a CEL if the downstreams are close enough to the cat. I went from 4 cats to two high flows and no CEL yet (knock on wood), mine is a '97 4.6 so not really a fair comparison either. Otherwise GOTTS 02 mod should do the trick. Looks GOOD man!

I meant clear not "fix" on the programmer sorry. Gotta o2 is pretty simple but will "fix" it. Like stated above hi flow cats should not throw a CEL. But I think we are hijacking this guys thread, best of luck to u.
