Second Hand Hyundai i40 Exhaust Manifold

Yes, all engine variants of the Hyundai i40 (2011–2015) have an exhaust manifold — it is the cast or fabricated pipe assembly that collects exhaust gases from the cylinder head and routes them toward the rest of the system. Both the 1.6 GDi petrol and the 1.7 CRDi diesel engines have one, so this is a genuine part for every variant of the car.

The Hyundai i40 ran from 2011 to 2015 with a facelift arriving in 2014, and fitment of the exhaust manifold is driven primarily by engine code rather than model year or facelift status. If the engine code matches — for example, the 1.7 CRDi D4FD or the 1.6 GDi G4FD — a pre-facelift manifold will very likely correspond to a post-facelift one, but you should confirm this with the breaker against your exact registration before purchasing, as minor running changes can occur across a production cycle.

Trim level does not affect exhaust manifold fitment on the i40 — the manifold is determined by engine code and fuel type, not whether the car is a Classic, Style, Premium or Sport. All of those trims used the same core engine variants, so the manifold will be the same across trims sharing the same engine; just make sure the engine code on the donor vehicle matches yours.

Yes, the petrol and diesel manifolds are completely different parts and will not interchange — the 1.6 GDi petrol (engine code G4FD) and the 1.7 CRDi diesel (engine code D4FD) have entirely separate cylinder head layouts and exhaust configurations. Always confirm the fuel type and engine code with the breaker to make sure you are buying the correct manifold for your car.

The exhaust manifold is bolted to the engine and cylinder head, so it is the same part regardless of whether the car is the saloon or the estate (Tourer) body style, provided the engine code matches. Body style does not influence manifold fitment on the i40, so focus on matching fuel type and engine code when sourcing from a breaker.

For the exhaust manifold itself, the Euro emissions era is less critical than it would be for downstream components like the DPF or catalytic converter, but it is still worth checking because manifold design can follow the emissions package of the engine build. The i40 diesel was sold across Euro 5 and Euro 6 production runs, and while the manifold may well interchange, you should confirm with the breaker against your registration that the donor car's engine specification matches yours before buying.
