hi
what is the part number on the donut gasket that goes on the end of the header? thanks

 

Exhaust manifold to front pipe gasket is 17451-21030 for an xB.

 

thanks a lot man. that thing was hard to find on the net with my limited knowledge of car parts.

 

You're welcome.
You ever try the parts microfishe on here? It seems to be the same thing Scion dealers get. Mine is all computerized, but basically the same. Things can get confusing if there are things like color coded parts or production splits, though.
