The tool for removing locking lug nuts without a key might work. It bites into the rounded bolt head to get a strong grip.
Other options are to reassemble and let a muffler shop finish the job or if all else fails, you could remove the header and cat together to allow easy access to the rounded bolt.
Sorry to hear you're having this problem. I just installed hfc's last night by myself with no problems. For those that haven't done this install yet, the importance of having a quality six point socket sitting squarely on the bolt head before applying torque can't be overstated.
Also,don't use impact wrenches near your wideband O2 sensors.
