After market exhaust going on 98 tang. Need to trick computer into thinking the oxy sensors are operating correctly to keep check engine light off. A schematic would be GR8..
buy a programer, try SCT they have programers that can add some HP and will shut off check engine lights aswell for when you do intake and exhaust mods :)

A quality aftermarket exhaust system (street use) would have the proper O2 sensor mounting hubs in the correct locations so as not to affect the reading.
Are the sensors hooked up? Is the check engine light on?
