    Catalytic Converter

    I have long tube headers and would like to install OBII catalytic converters. Which ones do you guys recommend that would last. The high flow ones might not last as long and besides they are not OBII complient. Need something quick to get smoged. Thanks guys. Did a search but could not find anything specific. 2000 WS6. 3" exhaust.

    Hopefully someone from CA will chime in - I didn't think LTs were even legal in CA?

    i use the bassani metallicats on the wife's car. they've lasted longer than the stock cats have on my black car. but, just like 2001NBMZ28 said, longtubes aren't legal in cali. anything that moves the factory location of the cats are not legal.
