GTO and 3000GT Rear Pre-Cat Eliminator Pipe This pipe directly replaces the factory small catalytic converter that is bolted to the rear turbo and goes down to the downpipe. The rear primary O2 sensor mounts in it on a Mitsubishi GTO GT4 VR4 3.0 V6 DOHC 24V and this can be used to mount a WB02 sensor for use on the rear bank of cylinders if your using a stand alone ECU This catless pipe replaces that pipe, but offers a much less restrictive exhaust flow. Use of a flanged nut may overlap the welds where the pipe meets the flange. The nut will still secure the precat pipe to the turbo, or you may opt to use a non-flanged nut, or include a lock-washer between the nut and flange to fill in the space against the flange.
