Ok, here's what happened... I installed an Injen Cold Air Intake, DC Sports Headers, and an Apexi N1 full exhaust system. When I took out the stock exhaust, I took my catalytic converter and gut it out, basically it's empty now, it's like an additional big pipe to the exhaust. So installed it, bolt it on to the headers and the Apex N1 exhaust. Then I went for a drive (sounds really really nice by the way) and the check engine light came on... Does anyone know what's going on? and how can I fix it please??
Thank you

I had to remove both from the stock headers and exhaust, then I reinstalled them on the aftermarket products... Do you think it's the O2 sensors?
