If you installed a larger downpipe with or without a cat and tried the antifoulers with the HO2S sensor did you get rid of the CELs or did you need to fix the CEL problem with HPTuners.

In other words, if you tried the anti-fouler mod -- did it work?

Please also post what downpipe you used, as well as if this mod worked or didn't work.

THANKS!
