The only sensors I'm aware of in our exhausts are in the cat secton- one front O2 sensor, one rear.

 

a friend of mine told me there is no sensor

 

No sensors!!!! Make sure you buy new gaskets though, my borla headers didn't come with them. Your local Subie dealership should have them for like $20 or so.

 

yeah, i just got some headers too, same ones, and I already got the gaskets. Is there anything we need to worry about or be careful about or make sure to do when putting them On? It's pretty much just take the old ones on, slap the new ones in, right? Cause one of my friends was telling me something that was confusing me....i think was just drunk or something

 

i need a new gasket and spring bolts b/c the whole exhaust needs to come off and my spring bolts have lost their spring.

 

when i did mine on my 03rs thoes bolts holding on the rest of the exhaust from the header, were a bitch, a real bitch, i ended up taking the mid pipe off too, so i could get a 5ft cheater bar on the wrench.

Well if i do it while I'm up in school, a friend of mine has air tools, so it should be pretty painless

but if i do this when im back home, then its cheater bar time.

 

Also make sure the engine is cool....... When me and my buddies did mine we had multiple burns when trying to take the o2 sensors off. Those are a pain in the ass by the way.

 

Air tools will be awesome for getting them off, but the borlas have a different bend to them than the stock headers. When I installed my borlas a couple of the bolts were annoing. I had little room to manouver my ratchet, and I am damn sure you wont get an impact wrench in there. All in all the install was pretty painless though. You will definitely be pleased, amazing sound all the time, from idle to WOT.

Bummer, live and learn I guess. You shouldn't need to take either of the o2 sensors out to install the header. Taking the whole exhaust off is an easier way to access it, but with the right extensions, sockets and just a 1ft cheater bar, you should be able to detach the manifold from the cats, then install the new header. Some drive up ramps would make things easier. Oh and if you have one of those "ratchet style" impact guns you should be able to access all the bolts just fine as it is much smaller than typical air guns. G'luck. Can't wait to get mine- :drool:

 

We had it on a lift, and it was a lot easier to install the headers with the exhaust off.
