Wow. So the Air/fuel sensor (or O2) is just monitoring cylinder 4? That might be scary! And it is closer than 18" from the port. That scares me more. Just wondering how that is working for you?

it's fine and not all that uncommon. I have a turbo'd car with the same setup - meter reads off port 4.
I'm a musician (multi instrumentalist) for 30 years so sound is most important to me VS a 2 hp gain or a shiny thing under my bonnet
Currently I have a Fujitsubo in my 1.8 that came with the car.
I dislike it as it sounds too subtle and flat. It goes through stock cat to Borla muffler ... Very unexciting at idle and at high rev , sound wise I would call this "The Bland Combo" even stock car sound better at high revs also , I know the Borla has a lot to do with it too but someone else said the Fujitsubo is low pitched in a previous post here.
My last setup screamed like a race car , high pitched & very throaty.
Was an Apexi "spiral " to a Car Make Corn's muffler... Will install after car passes inspection this week.

Can someone ID if this is a NA8 vs NA6 header?
The flange for the catalytic converters has been cut off.
Looks to be a 1.8. Only using my Google-Fu looking at the front left flange. I think. Don't trust me though
