Secondary Cats Question for the Experts

jballer123 · 10-29-2011, 07:42 PM

Would a stock 335i with the secondary cats removed pass the SMOG sniffer test in CA, I would guess the primary cats must do most of the cleaning work since there are no secondary cats on the N55 enignes, Thanks for the help :-)

i would say yes..the reverse would not be true as the secondaries wouldnt heat up enuff

Do they make you run on rollers with a sniffer up the tailpipe?

without secondaries you will be fine.

the primary cats are where you wont.
