and the mid pipe bolts up to my down pipe. now this is fine but it cuts out my second cat completely and when i install it my second o2 sensor is gone too. my question is if this second o2 sensor is removed will it have any negitive effects on performance / gas mileage? i can deal with the light on the dash, just wondering exactly how much this second o2 sensor really matters.
thanks in advance,
