Yeah, I tried that twice. First, when I installed the headers, and then again, when I realized the bung extension fitting didn't fit with the headers installed. That tunnel sheet metal is some strong stuff, especially right where the O2 sensor needs relief! I have a bung I can weld on somewhere, so I may go that route. The O2 sensor only has about a half inch clearance, or maybe a little less where it is right now on the Speed Daddy's.
