Exhaust Flex Pipe Peugeot 807 (2002-2014)

The exhaust flex pipe, also known as the flex hose or stainless steel braid, is a flexible component of the Peugeot 807’s exhaust system. It serves as a flexible buffer between the engine and the exhaust line, absorbing vibrations, engine movements, and thermal shocks to prevent cracks, gas leaks, and premature wear.

The exhaust flex pipe performs several critical functions including :

• Absorbing vibrations caused by engine acceleration, deceleration, and crankshaft movement to reduce noise and protect welds and joints.
• Compensating for movements and thermal expansion from rapid heating, cooling, or water exposure, preventing stress and cracking in rigid tubes.
• Reducing exhaust noise and gas leaks by maintaining tight and intact connections.
• Extending the lifespan of exhaust parts like the catalytic converter, silencer, and Y-pipe by minimizing mechanical stress.

These functions ensure optimal exhaust system performance and vehicle longevity.

Exhaust flex pipes for Peugeot 807 are typically made from high-grade stainless steel (inox) to resist high heat, corrosion, humidity, exhaust gases, and constant vibrations.

• Construction: flexible mesh or corrugated metal braid, providing greater flexibility than rigid tubes for improved vibration absorption.
• Sizes: Common diameters are around Ø63.5 mm, with lengths from 100 mm to 150 mm to fit existing exhaust lines easily.
• Types: Universal and model-specific options are available, suited to various Peugeot 807 engine and exhaust configurations.

Choosing the correct diameter and length is key to optimal fitment and durability.

Signs that the flex pipe may be worn or failing include :

• Dull or louder exhaust noises indicating possible gas leaks.
• Visible fraying or perforation of the stainless steel braid due to heat, moisture, and prolonged vibration.
• Potential failure of exhaust system joints causing further leaks or damage.

Early detection and replacement help maintain exhaust integrity and vehicle performance.

Replacing the flex pipe is relatively straightforward compared to other exhaust parts. Nevertheless, professional installation is recommended to :

• Ensure proper mounting and tight sealing with compatible gaskets and clamps.
• Inspect related exhaust components such as catalytic converters, the silencer, and Y-pipes for wear or leaks.
• Choose the correctly sized flex pipe kit (diameter and length) to prevent premature wear.

Regular inspections during vehicle servicing can extend the pipe’s operational life.

Exhaust flex pipes are used widely across Peugeot 807 vehicles, predominantly those with 2.0i petrol engines manufactured between 2002 and 2014, including MPV versions and related models sharing the EW10 series engine.

• The flex pipe connects the engine manifold or catalytic converter to the silencer and Y-pipe assembly.
• It optimally supports exhaust vibration absorption and thermal movement compensation for these petrol models.
• Some compatible flex pipe types are also suitable for similar MPV vehicles and related multi-brand platforms.

Always verify compatibility by engine code and exhaust system details before purchase.
