hi, iv put a decat pipe on my 93 wrx import. all went well until i went to put the lambda sensor back in..its a differnt size to the threaded hole..

is it a lamba sensor iv taken out? its 2 wires, red and black.was in the standard down pipe, just after the cat

is there one from a different model i can use that will fit the hole?

thanks,matt

Early classics had the lambda sensor in the manifold, only the post 97 classics have the lambda sensor in the downpipe.

what you have taken out is the cat temp sensor, which isnt needed on the decat just unplug and way you go
