ANOTHER CATLESS DOWNPIPE QUESTION

I have some fitted but they came with a small L pipe that the lambda sensor plugs in to

If you have fitted down pipes are the plug holes in the same position as the OEM down pipes?

The ones I purchased had a small L shape extension that the lambda sensor plugged in to It seems the car dose not like the exstension and it not reading the lambda properly

The car runs very well but start getting lumpy on idel, can this be deleted?

when I unplug / Remove the sensor the car runs great and no lumpy idaling,,,,
