What it does

The manifold collects exhaust from the ports and hands it to the turbo or the exhaust. Factory cast manifolds crack and warp with heat cycles, which leaks drive pressure and makes the tick you hear cold. A new manifold seals the ports again; a tubular header or turbo manifold trades some durability for flow and a faster spool.
