I heard that running an off-road H-pipe on a 4.6 can actually rob you of power due to the Check Engine light being on, and the computer holding the motor back a little bit. I have seen some sort of aftermarket wire harness that plugs into the O2 sensors in the H pipe, but I can't remeber who makes it. Does anyone no if this is true or if this product helps?? thanks in advance
