When replacing your exhaust manifold, it is always wise, to change the
gasket. We highly recommend this UPGRADED copper gasket when running an
aftermarket exhaust manifold. These special exhaust
gaskets are made from .043 in. thick solid copper, and are racetrack proven to
eliminate exhaust leak. They feature an embossed O-ring design to increase
sealing pressure around the exhaust ports, creating a tight, leak-proof seal.
Fits: Mitsubishi Lancer Evolution VIII, IX
