Resident Clubdub Debbie Downer. I'd love your ideas if you kept them to yourself. Subarus suck, get a new wife.
Never argue with idiots. They'll drag you to their level and beat you with experience.
Again at least I gave him my experience/op(opinion).. But thanks for your helpful criticism my friend .
EDIT: ON a side note I would recommend if he wants a header in the future just to wait and get the entire setup.. Save some money.. But if he plans on going the PNP setup then just go grimmspeed. And Use an up-pipe like the one I purchased or any other reputable brand.

False. Back in 2002 I gutted the stock up pipe and returned the sensor to its original location.. After about 300 miles I got a CEL for "EGT sensor low input". Which makes perfect sense because with the catalytic converter removed exhaust gas temperatures at the OEM sensor location are lower, so much so that it puts it out of the predefined range (on the low end) for CEL trigger in the OEM map.
There's no reason to install the factory EGT sensor in once you have removed the catalytic converter (it's just reintroducing another point of failure that can cause something to get sucked into the turbine). Any uppipe that includes an EGT bung should be plugged, and the resistor fix should be performed. I disable any EGT sensor DTCs with any car I tune that has a catted uppipe, but I still advise the owner to perform the mechanical fix as well.Originally Posted by MainFrame
There's one reason.. you're at your buddy's house out in bfe and the only thing you have that will screw into the bung is the sensor.. I would imagine without it the exhaust leak would be pretty bad.
But yeah, that's the wrong place to put an EGT sensor anyways, so the best thing to do is get rid of it.
