Anyone ever had problems with the bank 2 O2 sensor not being able to clear the firewall on an aftermarket header? Any suggestions would be great.

Yes indeed, the problem has happened before. A simple way to fix it is to take the header to a local muffler shop. Have them sell you a cap for the o2 sensor bung(it screws into the one that doesn't clear the firewall). Then have them drill and weld a new bung for the o2 sensor on the side of the pipe rather that it's current location. It should not be a pricey job so don't let them rip you off. Good luck and feel free to pm with any questions.
