They had to do a driving test and put me on the rollers since the OBD failed (thats what he said anyways). I failed quite badly

Here are the results:

Hydrocarbons: 0.37 my reading = 0.93--fail
CO 6.21 my reading= 5.58--pass
NOx 0.93 my reading= 2.04--fail

Ya, im thinking to try and just take out the accessport all together and drive it for a while on the highway and then go back for a retest. If that doesnt work (only $23 to try again), then im thinking ill try to replace the downpipe (which is a hell of a lot more work than trying the first method). What do you think?

Unless the cobb catted downpipe also removes one of the downpipe cats, in which case im running it with only one cat and thats probably contributing largely to the problem.
