Basically screw the anti spark plug foulers into the bungs that your going to weld in and screw the 02 sensors into the foulers. They will take the o2 sensor out of the main exhuast flow. Hence, tricking it into think there is a cat behind it. Someone correct me if I'm wrong here, but aren't the anti-foulers the same as the mechanical simulators that Justin uses on his midpipes?Hatedonmostly said:
