Haima S7 Exhaust Manifold Pipe – Part No.: 484Q-13-450

Let’s start with the basics—this isn’t just a “metal pipe” in your Haima S7’s engine bay. It’s the critical link between the engine and exhaust system that moves harmful  (exhaust gases) safely away: a tough, heat-resistant unit made of high-grade cast iron or stainless steel (both stand up to extreme temperatures), with multiple branched tubes, sealed flanges, and sometimes a heat shield. Mounted directly to the Haima S7’s engine cylinder head—connecting each cylinder’s exhaust port to the main exhaust pipe—it acts like Without it, exhaust gases from each cylinder would leak into the engine bay, causing overheating, reduced engine power, and even damage to nearby parts.

This exhaust manifold pipe is exclusive to Haima S7—always check your vehicle’s VIN to confirm fitment! It’s tailored to the S7’s 484Q engine specs: its branched tubes match the cylinder layout (ensuring equal exhaust flow from each 缸), its flanges align perfectly with the cylinder head and main exhaust pipe (no gas leaks), and its thickness handles the S7 engine’s high exhaust temperatures (up to 800–1000℃). Grab a generic manifold or one for other models? You’ll run into trouble: wrong tube spacing (blocks cylinder ports), weak material (cracks under heat), or poor sealing (causes exhaust leaks).

 Core Jobs: Guide Exhaust, Protect Engine & Boost Efficiency

As a non-negotiable part of the S7’s exhaust system, it does three key jobs to keep the engine running right:

Collect & channel exhaust gases: Each cylinder in the S7’s engine releases exhaust after combustion. This manifold’s branched tubes gather gases from all cylinders and funnel them into the main exhaust pipe—ensuring smooth, unobstructed flow (no backpressure that slows the engine).

Withstand extreme heat: Exhaust gases leave the engine at scorching temperatures. The manifold’s cast iron/stainless steel material resists warping, cracking, or corrosion from heat—preventing dangerous gas leaks into the engine bay.

Protect nearby components: By containing hot exhaust gases and directing them away, it keeps heat away from sensitive parts (like wiring harnesses, hoses, or plastic engine covers). This avoids melting or damage to these components.

This 484Q-13-450 exhaust manifold pipe only fits Haima S7 (484Q engine)—wrong fit means exhaust failure:

Fits These: Haima S7 variants equipped with the 484Q engine (matches cylinder head ports, exhaust system layout, and bolt patterns—confirm with VIN).

Won’t Fit These:

Other Haima models: Like Haima S5, 7X, or M3—different engine designs (cylinder counts, port spacing) mean the manifold can’t attach.

Non-Haima vehicles: Even if engine size is similar, their cylinder head and exhaust layouts differ (no functional fit; causes leaks).

S7 with modified engines: Aftermarket engine swaps or cylinder head upgrades change port sizes—original manifold won’t seal or flow properly.

 Installation & Upkeep (Pros Only—Heat & Sealing Matter!)

Installation: Must Be Done by Certified Technicians

Replacing this manifold requires precision—DIY risks leaks or engine damage:

Prep: Let the S7’s engine cool completely (manifold stays hot for hours!). Techs remove engine covers, disconnect the main exhaust pipe, and unbolt the old manifold from the cylinder head.

Clean & inspect: They clean the cylinder head’s flange (remove old gasket residue) and check for cracks (heat often damages the head’s surface).

Install new manifold: They place a new exhaust gasket (to seal), align 484Q-13-450 with the cylinder head ports, tighten bolts in a specific “crisscross” pattern (prevents warping), and reconnect the main exhaust pipe.

Test: They start the engine and check for exhaust leaks (using a smoke test or listening for hissing) to ensure a tight seal.

Maintenance: Key Checks to Avoid Failure

Inspect for cracks yearly: Look for small cracks in the manifold (heat causes metal fatigue)—cracks lead to leaks, reduced power, and loud exhaust noise.

Check gaskets every 30,000 km: Exhaust gaskets wear out from heat—replace them if you hear hissing or smell exhaust in the engine bay.

Avoid cold starts under load: Let the engine warm up before driving hard—cold manifold metal is brittle, and sudden heat can cause cracking.

Clean flanges during service: When replacing other exhaust parts, clean manifold flanges to remove rust or residue—ensures a tight seal.

Summary: Haima S7 Exhaust Manifold Pipe (484Q-13-450)

Exclusive to Haima S7 (484Q engine, confirm VIN for fitment), this part is a heat-resistant unit made of high-grade cast iron or stainless steel, with branched tubes, sealed flanges, and optional heat shield. Mounted on the engine cylinder head, it connects each cylinder’s exhaust port to the main exhaust pipe.

Key roles: Collect and channel exhaust gases smoothly (avoids backpressure to maintain engine power); withstand 800–1000℃ to prevent gas leaks; shield nearby parts (wiring, hoses) from extreme heat.

It fits Haima S7 variants with 484Q engine, but not other Haima models (e.g., S5, 7X), non-Haima vehicles, or S7 with modified engines.

Professional installation is required (cool engine first, clean flanges, tighten bolts in crisscross pattern, test for leaks). Maintenance: Inspect cracks yearly, check gaskets every 30,000km, avoid hard driving on cold starts, clean flanges during service. Original parts ensure proper fit, heat resistance, and leak prevention.
