I have 3'' exhaust with hi-flow converter (all from Buschur) and I recently installed their anti-fouler but I'm still getting the "ineffective cat converter" code from the ECU. Car has been dynoflashed for all mods so what should I try next? The constant CEL bugs the sh*t out of me and anyone who rides with me thinks my car is f'ed up... what else can I do?
