Downpipe Question

[KOMPLICATED]

What's the size of the stock cat? And are there any o2 eliminator w/ dump tube downpipes that bolt directly to it?

I beleive the stock exhaus are all 2.25" or maybe its 2"??
What is a dump tube downpipe? I think your a bit mixed up here. You can buy an o2 elim housing w/ external dump then get a downpipe to match that will accept the o2 I guess. Just go to victoryperfromance.com and check out what they have to offer as for o2 dumps.
Curious, you live in cali and want an external dump?? You ae crazy, I know the popo's will be all over you like stink on sh!t...

i was going through the site and i MIGHT be taking this out of context but i was reading on their site and came across this lil snippet "... and uniformly polishes air and fluid passages to .." and i'm sorry but you do not polish a fluid passage, that's just playing stupid. I know i'm nit picking but really, come on.
