Exhaust Flex Pipe Audi A4

The exhaust flex pipe (also known as exhaust braided hose) is a vital component of the Audi A4 exhaust system. It is designed to absorb vibrations and thermal movements between the manifold and the catalytic converter or silencer, preventing cracks. Typically made from stainless steel with either an Interlock or Braided liner structure, it ensures enhanced durability and longevity of the exhaust system.

Specifications vary depending on the model, engine, and generation (B5, B6, B7, B8). Here are the main references for Audi A4 exhaust flex pipes:

• A4 B8 Avant (8K5): Dimensions unspecified, compatible with 2.0 TDI 143 HP Diesel engines.
• A4 B8 General: 60 mm inner diameter, 90 mm outer diameter, 116 mm length, Interlock stainless steel.
• A4 B7 (8EC): 55.7 mm inner, 85 mm outer diameter, 100 mm length, Interlock stainless steel.
• A4 B5 1.6 (ALZ, 102 HP Petrol): 40 mm inner, 60 mm outer diameter, 80 mm length, Braided liner stainless steel.
• A4 B6 Avant (8E5): 55 mm inner, 85 / 81.5 mm outer diameter, 100 mm length, often includes pipe support.

All parts are brand new and provide original quality at reduced prices.

To ensure you select the right exhaust flex pipe, it is crucial to verify compatibility accurately :

• Use your vehicle's chassis number (VIN) to confirm generation and engine details (e.g., 8K5 for B8 Avant, 8EC for B7).
• Consult detailed online catalogs with filters by model, generation, and engine.
• Refer to manufacturer specifications and measurements such as pipe diameter and length.

This helps prevent installation errors and guarantees proper fit and function.

Signs that your Audi A4’s exhaust flex pipe may require replacement include :

• Hearing knocking or clicking noises from the exhaust system.
• Detectable exhaust gas leaks near the flex pipe area.
• Visible damage or cracks on the flex pipe during inspection.

Addressing these issues promptly helps maintain your vehicle’s exhaust system integrity and safety.

Repair or replacement of the exhaust flex pipe usually requires lifting the car to access the part properly. While sometimes partial removal of connected parts like the catalytic converter or manifold may be needed, complete removal of the entire exhaust system is generally not necessary.

Professional advice and installation guidance are recommended to ensure safety and effective operation.

Audi A4 exhaust flex pipes are constructed using high-quality stainless steel (INOX 409), known for its corrosion resistance and robustness. Key features include :

• Interlock structure or Braided liner design for flexibility and strength.
• Manufactured to meet or exceed original equipment standards for lasting performance.
• Special coatings to enhance heat resistance and reduce wear.

These manufacturing standards contribute significantly to exhaust system conditions ensuring safety and reliability over time.
