There are 2 types:

Catted: more expensive, but much less smell, a deeper tone, and NO CEL.
Catless: slightly more power, much more rasp, and more volume.

IMO if you're not keeping the car you should stop right there because even for a Stage 1 flash you're going to need a charge-pipe, and if you're not wanting to do that, then you're done. But if you are, then the charge-pipe and re-flash to Stage 1 is the next step.
Wrong. All down pipes are illegal. They change the M2s emissions.
