Today's update: Finally got both header off. I wasted a lot of time trying to get the O2 sensors out with the header still on the car. Its a dirty job trying to spray 'Bolt Off' from beneath and having it drip on you. Even if you manage to loosen the dang bolt, you're going to have a tough time getting enough slack in the O2 sensor line to twist it out. Better just disconnect the sensors from the car but leave it attached to the header.

In hindsight, I would recommend getting an O2 sensor specific socket. I didn't have a 22mm wrench and attempting this with an adjustable was NOT ideal. Ended up with rounded off some corner which I regret considering these sensors are $170 EACH for my 2001S. OUCH!!

Maxspeed claims their header weighs 19.2 lbs. On my scale it weighed in @ 18.6 lbs. Stock header weighed in @ 22.8 lbs. Saving roughly 4.2 lbs or ~18% of weight.
