how straightforward would moving the 02 sensor be? I know it is mounted on the primary cat in stock form, so would I want to just cut a mounting hole in the downpipe (past the headers) and call it good? Just to clarify, the sensor just measures the quality of the exhaust gas going into the cat, right?
right on....thanks for the pics. Did you notice any increase in performance from this mod? I have heard the standard 10 HP-ish guess-timates but I was just wondering what your butt dyno said? Is it worth it?
