These OEM Exhaust manifold gaskets look reusable?

Bout to install my efr turbo setup on. Considering how pricey the stock exhaust manifold gaskets are, curious if you guys think those pictured look ok to reuse or no?

They look good to me. May just want to do a light cleaning with a scouring pad and some sort of degreaser on the one that has more carbon on it.

I don't see any cracking on either, that's the real thing to watch out for that means they can't be reused. They typically can be used many times over.

those looks fairly low mile to me, i would also make sure that the manifold flanges are flat. i just lay a piece of sandpaper on the ground and do figure 8's

I'm just going to play devil's advocate here and say you can find the Nippon OEM style gaskets for fairly reasonable prices still (W0133-1757914).

Yours are probably fine to reuse, but these are gaskets I just did not want to have to replace in the off chance mine didn't seal on re-use (but I'm on the stock twins and maybe its less of a PITA for you to pull everything apart)

SpinningDorito: Thanks for the input. I do need to order another set of exhaust manifold nuts, I may just end up ordering new gaskets aswell and keep the ones I have as back up. Taking the single turbo manifold off is still a little bit of a pain just to swap out the gaskets but for sure not as bad as the stock setup like you mentioned.
