I have to replace my exhaust manifolds, and the ones I have for replacements don't have the hole for the O2 sensor to screw into. Can i just drill a hole in the exhaust itself right by the flange and weld a fiiting that will fit the O2 sensor and have it still serve it's purpose? Living in Cali sux with needing the smog!
