When Vast "piggifies" DPs, do they replace the main cats too?
The description on the website kind of sounds like they replace the main cats with new OEM cats but I wasn't sure. I have a bad cat code that I need to fix and I'm wondering if getting piggie pipes will fix that issue. I'd rather not get used cats since I don't know how much life will be left in them leaving the possibility of the problem coming back in a short period of time.

I'm certain they retain the existing main cat (would cost much more if replaced)
email them and see what options are available for your budget - I'm confident you will get a prompt reply :^)

I have a bad cat code as well, that's why I am going with piggies.
I think they are used, but I am not sure either. just buy them and send them your bad cat, they will send you a working cat and might charge you the $100 for having a bad cat.

FWIW, if you do have a bad cat, it would be one of the pre-cats...
since those are what are measured for cat efficiency in the stock configuration.
Piggie pipes remove those pre-cats and use the main cats for "cat efficiency". So unless both your pre- and main cats are bad, piggies will likely be fine for your needs.

I don't remember the exact code off the top off my head but it's the warm up cat efficiency code.
So that would be the precat and not the main cat? I guess that makes sense since the O2 sensors are before and after the precat so efficiency is based on the difference between the primary and the secondary O2 sensor.
