If you don't want to spend tons of cash, remove the secondary O2 from the pipe. Leave it connected electronically and ziptie it up out of the way. Go to your local exhaust shop and ask for an O2 sensor port plug and put the plug into the threaded port. This has had great success on all OBD2 and newer Hondas. If you can't find a plug email me and I can get one for you. Hope this helps!
