I guess you got that header from celica performance huh? Or from somewhere else? You don't necessarily need to have the O2's pluged in to run the engine, however, that doesn't mean it's not worth getting them both in, so don't interpret what Spedtoe says as "So I don't need the sensors pluged in..." You need them in. Running w/o the O2 can trigger little problems and cause the car to run funky... The first O2 on the header should fit fine, however, the lower O2 will need to have an O2 bung drilled and welded in... Also, the header will be roughly a foot short of the cat... so unless you've some fair welding skills... take it to an exhaust shop. -------------------- "It's ok to be naked girl... I'm an artist!"
