Well, my headers are 99% put on. The only issue im having is the location of the o2 sensor bung. I tried using an air hammer to dent the firewall in but for some reason it didn't work. I know it wouldn't be very advisable to do this, but could i grab an o2 extension and relocate the upstream to the downstream area temporarily until i can throw my car on a lift and use a small sledge hammer to dent the firewall. My other option is to buy one of the o2 elbows from ZZP.
