I have an Alien Head full exhaust that should be delivered the first of next week. Does the brocks header have a bung for the stock O2 senor, will it come with a bypass, or do I need to order a bypass from somewhere?
It comes with a "closed" bung that you have to drill out to input a sensor, but not hard to do. Just have to be carefull and not touch the bit to the threads...
