i always had a check engine light. even with the O2 extender and steel wool jammed in the hole. i figured i wouldnt pass with the light on. plus i dont have any tuning software to shut that off.
it worked out though. i went back to the factory cats and they are still in there. if i do anything it will be some FI or GTM high flow cats. also with out a tune the low end felt weak just running the RTP's.
