Friends, I'm new to this forum, please bare with if I not fluent with the lingos & abbreviations. Please I need ur advice on what to do. I have a 2011 black 370z nismo. Last month I got a new HKS hi-power titanium tip cat back exhaust system. 2 weeks after, I got an ARK R-spec hi flow catalytic converter. 3 week's later my service engine light came on, I went to the dealership, they said it's bcoz of the aftermarket cats (it messes up d O2 sensor). They advice me to put back d factory cats or go to a tuner shop to adjust d settings but it will void my warranty. What should I do now? Is this expected once u put on a HFC? Please advice.. Thanks!
