A2710501601 Exhaust Camshaft For Mercedes-Benz C180 C200 C250 W204 M271.860 1.8L

94610602622 Exhaust Pipe | Genuine Porsche Specification, Fits Macan/Cayenne Fuel Models

Tailored for the two popular Porsche SUV fuel models, with clear compatibility information for easy reference:​

Porsche Macan: Corresponding to chassis code 92A, covering production years 2014–2024. Specifically compatible versions include the Base Model (2.0T), Macan T (2.0T), Macan S (2.9T), Macan GTS (2.9T), and Macan Turbo (2.9T) — all equipped with petrol turbocharged engines.​

Porsche Cayenne: Corresponding to chassis code 970, with production years 2010–2017. Compatible versions include the Base Model (3.0T), Cayenne S (4.8L), Cayenne Turbo (4.8T), and Cayenne Diesel (3.0T), covering both petrol and diesel engine types.​
Important Note: This exhaust pipe is not compatible with the all-electric Macan (based on the PPE platform) or the 3rd-generation Cayenne (2018 and later, chassis code 9YA). To avoid incorrect purchase, it is recommended to verify compatibility by entering the vehicle’s VIN code in the Porsche EPC system for secondary confirmation.​
Core Functions: Safeguard Exhaust Efficiency and Engine Performance​
1.Efficient Exhaust Flow & Backpressure Reduction:​
Adopts a 304 stainless steel equal-diameter streamlined design with a pipe diameter of 55mm, reducing airflow resistance by 15%. This effectively prevents power loss (approximately 3–5 horsepower) caused by excessive exhaust backpressure. Meanwhile, it is adapted to the longitudinal engine layout, with the bend angle optimized to 120°, allowing rapid discharge of exhaust gas from large-displacement engines such as 2.9T and 4.8T. This enhances power response sensitivity during high-load scenarios like highway overtaking.​
2.Pressure Balance & Condensate Drainage:​
The pipe integrates a micro-perforated pressure balance structure, which automatically adjusts the pressure inside the exhaust system (normal operating pressure range: 0.1–0.3bar). Even during sudden acceleration, it prevents seal failure at connections due to sudden pressure surges. A condensate drainage groove is reserved at the bottom, making it particularly suitable for diesel models like the Cayenne Diesel — condensate produced by diesel engine combustion can be drained through the groove, reducing the risk of internal pipe corrosion and extending service life by 30%.​
3.High-Temperature Resistance & Corrosion Protection:​
Constructed from 304 stainless steel, it has a high-temperature resistance limit of 650°C, easily withstanding the high-temperature exhaust gas (approximately 600°C) at the exhaust manifold outlet of turbocharged models. Compared with ordinary carbon steel pipes, its oxidation resistance is improved by 40%. The surface undergoes passivation treatment, which resists corrosion from rain, snow, and road deicing agents, making it suitable for use in cold and salty regions such as North America and Northern Europe.​
On-Vehicle Application: The "Key Connection Node" of the Exhaust System​
Installation Location & Mounting Method​

For Macan models: The pipe is installed at the rear of the engine compartment. One end connects to the exhaust manifold via a flange (with a conical seal seat), and the other end is suspended under the vehicle body by rubber shock absorbers, extending to the mid-section catalytic converter. The pipe height from the ground is approximately 220mm, meeting the ground clearance requirements for urban road use.​

For Cayenne models: The pipe is located under the left longitudinal beam of the chassis, fixed by 5 rubber shock absorbers. It can absorb pipe displacement caused by engine vibration (maximum displacement: ±5mm).​
Synergy with Surrounding Components​
One end of the pipe connects to the exhaust manifold, and the other end connects to the catalytic converter or Diesel Particulate Filter (DPF). A mounting boss for the oxygen sensor is reserved in the middle section, which provides exhaust gas concentration data to the Engine Control Unit (ECU), helping optimize fuel injection volume and reduce emission errors (error can be controlled within ±0.5ms).​
Replacement Indicators​
It is recommended to inspect the pipe after the vehicle has traveled 80,000 kilometers or been used for 6 years. If there is more than 20% surface corrosion, abnormal noise at idle, or the engine fault light is on, the pipe should be replaced promptly to avoid damaging subsequent components such as the catalytic converter.​
