Installing long tube headers (which will delete cats) .
The pre cat o2 sensors are to fit in the bungs on the header collectors (with harness extension) I assume.
Since no cats then the post o2s will be useless (as they are there to monitor catalytic efficiency?). The post o2 bungs end up about 6 inches past the collectors- Is it ok to put the wideband in place of one of these sensors and eliminate them in tune? Easier than welding new bung, adding defoulers (which always seem to be hit/miss). Is that The prefered way? is there a prefered bank? -or whichever is best for harness routing.
