100 Cell cats vs. 200 Cell cats
#16
Hello all,
I live in the lovely state of California where emissions checks are a necessity to register my 996TT. I am currently in the market for a new exhaust system and was wondering if a 100 cell cats will be enough to pass Cali Smog Checks. Will 200 cells be enough? Is there much of a performance advantage going 100 vs. 200?
Thanks!

If you are unsure if you can pass or not why not test before you go to the test, the shops in US must have the same test equipment . If you dont pass with 100 cels try add E85 that will probably solve the issue but not to much i assume you have E85 in Cali. .

okay if you have 1" and you fit 400 cells in it they are jam packed but if you put 100 cels there is more room and air flow
in texas you should have no issues with 100cell cats

I'm thinking about switching from 200CEL cats to 100 CEL cats but it looks like the cats alone are about 1k...
which ones are you going to buy?

The only issue in Cali is that smog tests require a "visual inspection". An inspector can fail you with aftermarket exhaust even if you pass the sniff test. However I don't know of any test stations that failed based on visual inspection. If you want to play is safe, get a europipe that look like factory pipes or RUF that are modified factory pipes.
