This explains why I'm always seeing uneven readings on my O2 sensors. The airtube only fed the passenger side cat by bad design. The drivers side sensor seems dead half the time. Probably extra back pressure there.
Will running it lean(ish) keep the cats from getting clogged up? I dont race much in the winter anyway
