100 Cell Cats and smog test
the car failed Calif smog test
. Had a used Remus with 100 cell cats and about 15K miles on the exhaust. Swapped the factory stock back on and it passed with flying colors.
Does anyone know what the usual life span of aftermarket 100 cell cats? Anyway to refurb the cats?
I really miss the sound and performance of the Remus....

# 1 an aftermarket exhaust wont pass visual .
If you get lucky enough and smog guy doesnt know what he is looking at then you can get away with it.
#2 you will need a minimum 200 cell catalyst to pass california emissions.

#3 100 cell catalyst are not efficient enough to pass smog requirments and most will trigger a cel light.

passed visual without any problems.
Funny thing is that my friend who has the same exhaust, perhaps fewer miles, passed ok without problems!
do you have any idea how many miles 200 cel cats are good for? I'm wondering if running a sport exhaust means ponying up $2-4K dollars every few years to pass smog

Are you guys telling me that my Europipe is not going to pass Maryland emissions when it's due because it has 100 cell cats? Dude, that sucks. What am I going to have to do to get around that, replace my stock exhaust just to go through emissions? I think my ECU may have also had the readiness codes and OC sensors disconnected when I had it flashed. The day of the emission test should be good for a couple of laughs.

Yes, it's all about SA, 100 vs 200 is meaningless. EP's other advantage is that they actually look OEM. As for the OP, I'd just swap the stockers on/off every two years to pass.
