Exhaust Flex Pipe Peugeot 807 (2002-2014)

The exhaust flex pipe, also known as the exhaust flexible hose or stainless steel braid, is a flexible component in the Peugeot 807's exhaust system. It acts as a flexible buffer between the engine and the exhaust line, absorbing engine vibrations, movements, and thermal shocks to prevent cracks, gas leaks, and premature wear. This flexibility protects welding points and exhaust connections from damage caused by engine motion and heat expansion.

The exhaust flex pipe serves several key functions in the Peugeot 807:

• Vibration absorption : It isolates engine vibrations from the rigid exhaust system, reducing noise and protecting joints and welds.
• Movement and expansion compensation : It absorbs thermal expansion and contraction movements, preventing cracks and stresses in rigid exhaust pipes.
• Noise and leak reduction : It ensures airtight connections, limiting exhaust noise and maintaining engine performance by preventing gas leaks.
• Durability enhancement : It reduces mechanical stress on the catalytic converter, silencer, manifold, and Y-pipe, extending their lifespan.

These functions help maintain optimal exhaust system performance and vehicle reliability.

The flex pipe for Peugeot 807 is mainly made from high-quality stainless steel (INOX 409) to withstand extreme heat, corrosion, moisture, chemical exposure from exhaust gases, and constant vibrations. Key manufacturing features include:

• Flexible mesh or corrugated metallic weave for enhanced flexibility compared to rigid pipes
• Available in various diameters (commonly Ø63.5 mm) and lengths (e.g., 100-150 mm) to fit different parts of the exhaust system
• Durable stainless steel construction ensuring long-term resistance to thermal and mechanical stresses

This construction supports reliable performance and easy installation in the Peugeot 807 exhaust system.

Common symptoms indicating the flex pipe may need replacement include:

• A dull, unusual exhaust noise indicating potential gas leaks
• Visible fraying or perforations in the flexible mesh due to heat and prolonged vibration exposure
• Signs of exhaust gas escaping prematurely, sometimes due to broken seals in the exhaust system

Addressing these symptoms promptly helps maintain engine performance and reduce noise pollution.

The flex pipe is one of the easier exhaust components to replace but professional installation is recommended to check surrounding parts like gaskets, catalytic converter, silencer, and Y-pipe. Important points include:

• Choosing the correct diameter and length to fit the Peugeot 807 exhaust system for optimal function and longevity
• Inspecting the entire exhaust system during replacement to prevent further issues
• Regular maintenance checks to detect early signs of wear or leaks

Routine attention ensures the exhaust system remains efficient and compliant with emission standards.

The exhaust flex pipe is used in:

• Standard passenger vehicles like the Peugeot 807 (2002-2014) 2.0i petrol, acting as a connection between the engine and exhaust manifold
• Vehicles without a traditional driving license (voiture sans permis) where it helps reduce noise and absorb vibrations
• Exhaust systems using stainless steel parts for enhanced performance and durability, including catalytic converter assemblies

This component aids in meeting noise regulations and ensures smoother engine operation across models.

When searching for an exhaust flex pipe suitable for your Peugeot 807:

• Ensure the pipe matches your vehicle’s engine type and size, such as 2.0i petrol models
• Verify diameter and length measurements to ensure compatibility and proper fitment
• Check manufacturer details and codes to confirm you are selecting a part designed for your specific model
• Look for quality materials like stainless steel to ensure durability and resistance to heat and corrosion

Proper selection helps optimize exhaust system performance and longevity.
