I have the high-flow cat from Solo, and recently installed their cat-back exhaust. Unfortunately, the position of the O2 sensor bung makes it point at the frame, so I can't use one of the long extenders. I tried a shorter extender, about 1.25" long, but the code still sets. Is there another solution to keep the CEL off? My car is due for inspection by the end of this month, and I'm running out of options.
