Typically I am a fan of OE parts. I say OEM.

im using cometic, had to remove the rivets with my aftermarket manifold, but seals fine.... much easier cleanup if you ever have to remove it

eh?

Use the cometic if you have a decent exhaust manifold. As flatrate said the rivets need to be removed if you have an aftermarket manifold.
I used it and reused it ( w copper spray) many times and it never leaked with my 6boost. The oem will seal better with those ebay manifolds.
Also shop around as you can find it for much cheaper than $35..

thanks for the feedback guys. At this time Im just replacing stock with stock manifold. I was leaning to use the Cometic because of its reusability, as long as it doesn't have any issues with the stock cast iron ex mani.

im pretty sure with the stock manifold the rivets can stay in place
