I have an 03 WRX I have the centre cat removed and want to remove the up pipe cat, will I pass an MOT with the standard downpipe, or do I need to put a PPP downpipe on before I go for MOT, also does an sti 8 std up pipe have a fitting for the egt sensor or is it removed altogether, as have been offered one without sensor hole, I have seen after market ones both with and without, I thought I should have the sensor fitted and just disable the P0546 high temp CEL using my tatrix cable.

Thanks

Darren
