Exhaust manifold

A loud ticking or tapping noise from the engine, especially when cold, a strong smell of exhaust fumes inside the cabin, drops in fuel economy, or sluggish acceleration usually point to a failing exhaust manifold. Common signs that the manifold itself needs replacing rather than just a gasket swap:

• Visible cracks across the manifold body or runners
• A warped flange that won't seal even with a fresh gasket
• Snapped or stripped studs at the cylinder head
• Heavy corrosion that can't be cleaned back to good metal
• Persistent leaks after gasket replacement
• A check engine light triggered by exhaust upstream sensors

The manifold bolts directly to the cylinder head, collecting hot exhaust gases from each cylinder and channeling them into a single downpipe. A cracked or leaking manifold doesn't just hurt performance, it can let dangerous fumes into the cabin and overheat surrounding components like wiring and the turbo, so persistent leaks aren't worth ignoring.Tracking down a sound replacement online is the slow part, with exhaust manifold listings spread across breakers, performance specialists, and parts marketplaces with very different prices.Parthunt24 brings used exhaust manifold listings together from marketplaces like eBay, Ovoko, RicambiPro, Opisto, Proxyparts, Ecooparts, Autoparts-24, Totalparts. Compare 286 options on price, condition, and fitment, then head to the marketplace once you've found the right manifold.

An exhaust manifold is a critical engine component that collects exhaust gases from multiple engine cylinders and directs them into a single pipe. Made of heat-resistant cast iron or stainless steel, it reduces backpressure, boosts performance, and helps manage engine heat. Over time, these parts can crack or leak, resulting in noise and reduced efficiency.The OEM part number is the first thing to cross-check, followed by the voltage rating (commonly 4.4V, 5V, 7V, or 11V), thread size, and reach. A plug with the wrong reach can sit too deep in the chamber and strike the piston, while a wrong-voltage plug will burn out within hours of fitting. Run a Parthunt24 search using the OEM code or your vehicle details, and the side filters (Category, Manufacturer, Series, Model, Modification, Price) narrow the list to plugs that match your engine. Each entry opens on the marketplace it's hosted with, where the seller handles the product description and the order itself.

• Vehicle compatibility: Match make, model, year, engine code, and OEM part number.
• Engine configuration: Inline, V-engine, boxer, and other layouts use different manifold designs.
• Turbocharged vs naturally aspirated: Turbo engines often use integrated turbo manifolds.
• Number of ports: Verify cylinder count and port alignment.
• Sensor mounting points: Check oxygen sensor and EGT sensor locations.
• EGR compatibility: Some manifolds include integrated EGR passages.
• Mounting flange design: Verify bolt pattern and flange alignment.
• Material type: Cast iron vs stainless steel construction.
• Heat shield compatibility: Some vehicles require specific heat shield mounting points.
• Catalytic converter integration: Certain manifolds include integrated catalytic converters.
• Left-hand vs right-hand drive differences: Routing may vary on some vehicles.
• Condition: Inspect for cracks, warped flanges, stripped threads, and corrosion.

When the seller's listing loads, work through it carefully before paying. A used manifold can look clean in a photo while hiding hairline cracks between the runners, warped flanges, or seized studs broken off in the threads, so close-ups of the flange face and each port matter more than the headline shot.

• Photos: Clear shots of the flange face, each port, and any sensor mounting points.
• Seller reputation: Buyer feedback, sales history, and review quality.
• Compatibility: OEM number checked against your engine code and variant.
• Included components: Bare manifold, with gaskets, studs, heat shield, or sensors?
• Condition: Cracks across runners, warped flange surface, stripped threads, corrosion depth.
• Testing: Notes confirming flange flatness and absence of cracks.
• Warranty and returns: A clear path if the manifold arrives cracked or warped.
• Shipping: Sturdy packaging to prevent flange damage or further cracking in transit.

Once the listing checks out, complete the purchase on the marketplace.

Exhaust manifold price varies a lot with the vehicle, the material, and what's integrated into the casting. A used cast iron manifold from a common petrol hatchback opens at €40-€100, mid-range stainless steel units sit at €120-€300, and OEM integrated turbo manifolds or those with built-in catalytic converters can push past €500.Searching Parthunt24, replacement exhaust manifolds appear from as low as 8.82.

• Material: Cast iron sits below stainless steel, which sits below performance tubular designs.
• Integration: Manifolds with built-in turbo housings or catalytic converters cost more.
• Brand: OEM sits at the top of the range; quality aftermarket sits below.
• Vehicle rarity: Common engines are cheaper; specialist applications cost more.
• Inclusions: Gaskets, studs, and heat shields bundled bump the exhaust manifold price.

Stacking exhaust manifold prices side by side on Parthunt24 makes the gap between a cracked pull and a crack-free unit obvious.

A failing manifold seldom causes trouble in isolation. The same heat cycling and pressure spikes that crack the manifold often damage neighbouring components, and exhaust leaks upstream of the catalytic converter can throw fault codes on healthy sensors, so check the surrounding parts before fitting a fresh manifold. Browse these on Parthunt24:

• Lambda probe: The oxygen sensor reads incorrectly when exposed to a manifold leak; worth testing before replacing.
• Catalytic converter: Damaged by unburned fuel when the manifold seals fail.
• Exhaust heat shield: Cracked or missing shields let heat cook surrounding wiring and plastics.
• Exhaust gas temperature sensor: Mounted near the manifold and easily damaged by a leak or snapped studs.
• Downpipe: Adjacent flange wear often coincides with manifold cracks.
• Cylinder head: Snapped studs may need extraction or thread repair.
• Engine: Persistent leaks can damage valves and exhaust ports over time.
• Exhaust studs: Heat-cycled studs almost always need replacing.

Pinning down a sound exhaust manifold across forums and breaker yards takes time once turbo integration, sensor cutouts, and material choice enter the mix. Every compatible listing lands on a single Parthunt24 page, with material, condition, and price laid out together.Cast iron, stainless steel, and integrated turbo manifolds across most marques on European roads sit in the same results. The whole comparison now fits into one search. Compare prices, find the best deal, and buy an exhaust manifold for your car through Parthunt24 today.
