Are you talking about the factory exhaust manifold or do you want to replace the stock one with aftermarket header? If you want a stock manifold for a 1.6 dohc i have one that is in mint condition from when i changed to turbo.
I have one of the corksport headers on my festiva. I'm going to be parting it out in a month or so and selling the engine and header. The paint burned/melted off the first time I ran the engine, otherwise it's in perfect shape.
