Do you think I could use this between my header and the block?

How hot does the exhaust on an S4 NA get? I've heard 2000F Is that true?

I don't wanna spend 30 bucks just for a gasket and have to wait two weeks. I want the perfomance NOW

 

1800F is not unheard of at the exhaust manifold.

2000F is probably a bit of an exaggeration.

 

Just get the stock gasket (metal), it's definatly worth the wait instead of an exhaust leak that drives you crazy.
