Cna anyone tell me if headers will make my 93 mark8 fail emissions even if it still had the cat? Does anyone know who might be having an extra set lying around somewhere to sell?

Supercoupeperformace.com has them, Kooks makes them for him exclusively, I don't know of any other manufacturer who makes them for the Mark VIII, hope that helps.

I got them and passed the test just fine

They absolutely do not, we have them too. We are having a group buy on these in a couple of weeks.

how much will the price be with group buy?

and when will the next time be that we do a group buy for them again?

No prices set yet. We will have the header group buy after the fuel systems one we just launched this week.

When you put headers on, what kind of high flow cats would be needed?

no cats if you can, but we have the same air, I said yes to cats. but it is up to you. mine are magnaflow. the groop buy is a good Idea!!!!!
