I put the flowmaster flow fx cat back kit on about 6 weeks ago and twice I’ve gotten the check engine light with the code P0402 which is the EGR valve is flowung more exhaust gases that it should. Has anyone else had problems when they switched their exhaust systems or should I just switch back to stock and be done with the problem?
