Exhaust Renault Vel Satis (2001-2009)

The Renault Vel Satis exhaust system for models including the 2.2 dCi 150 HP Diesel G9T 702 includes parts such as the rear muffler (silencer), flexible pipe, and various options for universal and sport silencers. These parts are designed to fit the vehicle's specific exhaust setup and can be sourced from multiple suppliers.

Yes. For example, the rear muffler for Vel Satis BJ 2.2 dCi 150 HP (BJ0E, BJ0F, G9T 702) features an assembly on the front axle side with a diameter of 324 mm and is compatible with ventilated perforated discs. Flexible pipes typically have an internal diameter of 35 mm and are 150 mm in length, positioned between the engine and the silencer.

For Vel Satis Phase 2 models, custom exhaust options include universal race catalytic converters with different diameters (58, 63.5, 70, or 76 mm) capable of supporting up to 4.0 L / 600 HP engines. These options often come with sport mufflers and are tailored for performance while maintaining durability and regulatory compliance.

The Renault Vel Satis measures approximately 4.85 m in length with a 2.84 m wheelbase and weighs about 1750 kg. These dimensions and the high-pressure ECD-2UP DENSO injection system for diesel engines impact exhaust gas flow rates and compatibility of exhaust parts.

Krosfou offers original, high-quality exhaust parts manufactured in Europe with stainless steel INOX 409 material. Their products comply with European standards and have TÜV SÜD certification, ensuring reliability, durability, and performance equivalent or superior to original equipment.

All parts come with a 3-year warranty and free returns within 30 days for unused products in original condition.

Compatibility can be confirmed by providing the vehicle identification number (VIN) or original part reference. Proper fitment depends on engine type, Euro standards, and other technical details. It is essential to ensure parts match the exact model and assembly specifications for optimal performance and safety.

Professional installation following manufacturer instructions is advised to ensure correct assembly, including replacing necessary gaskets and sensors.

When replacing the exhaust silencer or muffler, ensure the replacement matches the original specifications for length, diameter, and assembly points. Using parts made from high-quality stainless steel enhances durability and corrosion resistance.

It is important to replace all worn or damaged components affecting the exhaust system’s integrity, including gaskets and flexible pipes, to maintain proper function and emissions control.

Proper maintenance includes regular inspection of exhaust parts for leaks, corrosion, and physical damage. The catalytic converter and DPF must be functioning correctly, and sensors should be replaced as needed to ensure compliance with emissions standards.

• Avoid excessive short trips that prevent the engine and exhaust from reaching operating temperature, to allow soot burning in the DPF.
• Use appropriate fuel and adhere to scheduled replacement of spark plugs, oil changes, and sensor checks.
• Ensure professional installation of replacement parts following factory guidelines.

Following these recommendations will help extend the life of the exhaust system and maintain vehicle performance while reducing emissions.
