    2002 allroad 2.7T tip w/P1176 & P1177

    Just replaced the original cats w/Bosal aftermarket and these codes popped up.

    I did some searching a few weeks ago, seems like this is due to faster airflow past the rear O2 (post-cat) sensors.

    I recall a couple of aftermarket extenders that fix this problem but now can't recall where to find them.

    Any help is appreciated!!

    Hello,

    Use any decent Internet search website page and search for the following "O2 sensor extenders".

    But I would consider using the correct catalytic converters, just my thoughts.

    And the reason I'm here asking is because I came up empty on that - and many other - searches. I did eventually find what I was looking for however.

    The cats (from Bosal) are advertised as 49-state compliant and application specific to the AR 2.7t for street driving, not racing or performance tuning.
