I already know that the 97 does not have the 02 sensor mounted in the cat but in the b-pipe. The guy is selling it for like 50 bucks. Sounds like a good deal but I would have to drill a hole into the 97 cat and relocate the sensor into my greddy sp2?

Is this just all too much work or should I go for it?
Plus, if I relocated it will the readings throw any codes?

Anyone did this before?
