I agree. It looks like MMW headers look like a well thought out product. On a NA motor, you will see the best performance gains with 4-2-1 setup giving you a stronger torque curve where you make your power most; low to mid RPM. The question is, are the MMW headers made of true T-304 SS or just coated like Meagan products?
The anti-fouler trick is the same as the mechanical CEL eliminator. 2 anti-foulers from the autoparts 'HELP' section are threaded together with the upper one drilled out w/ 1/2" bit to accomodate the O2 sensor. This is threaded into the S-pipe. It pulls the sensor out of the exhaust stream so that it gets a skewed reading, thus, no CEL.
