I have an 06 GT with Kooks long tube headers. I blew the manifold gasket on the drivers side. I was going to have it replaced at an exhaust shop but decided to go to the dealer. My mistake, I was charged 6 hours for labor. Looking to find out if this is correct or a bit inflated.

 

Have you ever replaced it yourself? Exhaust manifolds and headers are a PITA.

 

I'm not saying it's an easy job but 6 hours for one gasket!
