What It Does & How It Helps
The exhaust manifold collects the exhaust from each cylinder and feeds it to the turbocharger. It lives through extreme heat cycles, so cast manifolds crack and warp and the studs that hold them break. A cracked or leaking manifold ticks on a cold start, lets exhaust out before the turbo, and costs spool and power. Replacing it with fresh gaskets and hardware seals the hot side again.
