Currently I have a yonaka catback. Im wanting to get this, to replace everything from headers through the cat and right before the yonaka. I know this will delete the cat, #1 will this fit correctly? Anyone running these? And #2 will i have any mechanical issues with O2 sensors or the like

get what?
you are not going to get mechanical issues with o2 sensors, you are going to get electronic issues (ECU will not like it)

It looks like it's missing a primary O2 but has the secondary.

As far as fitment - it says it'll fit so probably?

So long as you understand you'll have a CEL, some potential running issues, a loud-*** car and a whopping 2hp gain, I say go for it if that's what you want.

DC Sports?!?
they discontinued products for d17 engines.
that site's 4-1 header also looks quite different than what I have. Those products are counterfeit, likely. The welds are too bad to be from DC sports
