What does an exhaust donut do?
For all flared joints, there is a donut-style exhaust gasket that prevents gases from escaping into the atmosphere. It fills the gap in the flare and creates a smooth passageway for the exhaust to go through.
How tight should exhaust donut be?
Just snug is enough. The exhaust pipe does swivel at this joint, but it should not be loose in any way when you try to wiggle it.
Can you reuse exhaust donut gasket?

When installing Fel-Pro exhaust manifold gaskets, if there is a smooth, metallic side and a composite side, the metallic side should be installed facing out, meaning toward the exhaust manifold.
Can you over tighten exhaust bolts?
Exhaust flanges that are improperly tightened or torqued can cause many problems, including exhaust system leaks; associated component failure of gaskets and studs; and premature system fatigue and failure.
