I recently bought a set of Stillen ss headers used from a friend. I was wondering what is a good gasket to use? Also when you(people that have Stillen) buy a set headers new what hardware comes with it? Thanks

 

OEM gaskets work best.

 

OEM gaskets are a good choice. Yes they cost about $70 (4), but you do not want to be replacing cheap gaskets at 10,000 miles.

Remember that the manifold uses double-threaded studs not bolts. Reuse them.

OEM nuts should work. Loktite is a given.

Header-to-catalytic converter hardware: buy quality stainless steel hardware at a auto store not junk at Home Depot.

 

Reuse your stock gaskets. The ones that go between the header and head. Do not use a aftermarket gasket there or you will be crying when it pops in a few days.
