Time for an emissions test, what cats for TT?

But theh are also like double the price of most other units out there for a pair.

Before I buy them, just wanted to hear other peoples experience on this kind of situation. Surely there is someone else out there who has a TT setup and had to use CATS to do an emissions test?

Do they do a sniffer test as part of your emissions test? Here, they just do an obd2 test and some test facilities will do a visual for cats. I run 100 cell mil spec cats just for the visual effect if I were to get pulled over and the police looked. They wouldn't pass a sniffer test.

Unfortunately, I am sure they do the real deal, a sniffer test and all. Because the engineer told me they will put the car on a dyno and I will get a graph of the emissions through a few runs, or something like that.

Sounds like you're pretty much going to have to go with the cats that your tuner (Seb?) told you to go with.

This. I've got the same FI 100 cell cats, but I can get away with murder as long as I don't have a CEL.

If they only inspect for CEL in certian states, why don't you just use downpipes (no cats)?

Ive had no CEL with my 3" AAM DPs for over 2 yrs.

Yup I might have to, but just wandered if it is overkill.
All good I will order them soon.

The catless smell got old for me many years ago, and the Z was the daily driver at the time.
