The factory driver’s side exhaust manifold is pinched down to allow for steering shaft clearance, which actually isn’t required. As a result, this manifold only flows 80% of the passenger side. This full bore exhaust manifold restores exhaust flow balance, improving power and reducing EGT. Made from high-silicon ductile iron, the Full Bore Manifold is a direct, bolt-in replacement for the factory manifold and is even drilled and tapped to accept the most popular EGT probes.
