Exhaust Peugeot 607

For the Peugeot 607, the exhaust system includes key components such as flexible pipes, rear silencers, standard exhaust pots, and catalytic converters. These parts are designed to absorb vibrations, reduce noise, and manage thermal expansion within the exhaust system.

The flexible pipes typically have diameters ranging from 55 to 60 mm with variable lengths between 100 mm to 300 mm. Catalytic converters and silencers are selected according to the engine type and model year to ensure the best match and emission control.

The Peugeot 607 was produced from 1999 to 2012 with various petrol and diesel engines, each requiring specific exhaust components:

• 2.0 HDi diesel (110 CV) from 1999-2006
• 2.2 HDi diesel (136 CV) from 1999-2004
• 2.7 HDi 24V diesel (204 CV) from 2004-2011
• 3.0 V6 petrol from 2000-2011

Each of these engines requires tailored exhaust parts such as pipes, silencers, and catalytic converters to ensure optimal performance and compliance with emission regulations.

Matching the correct catalytic converter to your Peugeot 607 depends on several key factors:

• Exact vehicle model and production year
• Engine size and fuel type (petrol or diesel)
• Emission standard compliance
• Presence and type of sensors such as lambda or pressure sensors

We recommend verifying compatibility by using your vehicle’s VIN or engine code on parts supplier platforms or consulting technical support to ensure you select an original and perfectly matching catalytic converter that maintains emission control and engine performance.

The exhaust system on Peugeot 607 vehicles often includes sensors such as oxygen (lambda) sensors and pressure sensors. These sensors monitor the exhaust gases and emissions, allowing engine management systems to adjust air-fuel mixture and improve fuel efficiency while reducing harmful emissions.

• Lambda sensors ensure proper catalytic converter function by measuring oxygen levels.
• Pressure sensors monitor backpressure and the status of Diesel Particulate Filters (DPF) where equipped.

Replacing or matching exhaust parts with incompatible sensor fittings can lead to engine errors and emission faults. Always verify sensor compatibility when purchasing or installing exhaust components.

Yes, Peugeot 607 diesel models, especially those equipped with modern diesel engines such as the 2.0 HDi, 2.2 HDi, and 2.7 HDi 24V, include Diesel Particulate Filters (DPF) to meet emission standards. The DPF traps soot particles to reduce pollution caused by diesel combustion.

• DPFs require proper maintenance and are designed to regenerate by burning off accumulated soot at operating temperatures.
• Replacement of a DPF must be complemented by suitable catalytic converters upstream and downstream of the filter.
• Incorrect or partial replacement can lead to engine warning lights, poor fuel efficiency, or failed emission tests.

Professional installation and adherence to manufacturer instructions are essential for maintaining your Peugeot 607’s emission control systems.

Krosfou supplies new, original exhaust parts such as Diesel Particulate Filters (DPFs) and catalytic converters with a 3-year warranty covering use up to 100,000 kilometers. This warranty ensures that the parts meet high quality and performance standards.

Conditions for warranty coverage include:

• Professional installation by a specialized garage
• Use of correct gaskets, sensors, and injectors during fitting
• Following manufacturer’s installation and maintenance instructions
• Avoiding negligent or improper use, such as limiting vehicle use to short trips preventing DPF regeneration

For warranty claims, a fully completed technical support form is required. The warranty covers repair of the product at the factory and does not cover indirect costs such as vehicle immobilization.

Yes, unused and unused parts purchased for a Peugeot 607 can be returned under Krosfou’s Free Return policy within 30 days of receipt, provided they meet these conditions:

• Product is in original, unused, and undamaged condition with all accessories
• Returned in original packaging
• Not a custom "manufactured to order" product

Returns require prior written agreement from technical support. The returned product must be properly packed with the returns number clearly displayed on the outside of the box. Krosfou will refund the original payment method minus initial delivery charges where applicable.

For deliveries outside the European Union, the customer is responsible for return shipping costs.

Many Peugeot 607 models feature two catalytic converters in their exhaust system — typically a main catalytic converter close to the engine and a downstream catalytical converter before the tailpipe. However, the vehicle usually has only one tailpipe where exhaust gases exit.

• The purpose of having two catalytic converters is to improve emission control by processing exhaust gases in stages.
• The single tailpipe then safely directs these cleaned gases out of the vehicle.

This arrangement is common in modern vehicles to meet stringent emission standards while maintaining optimal engine performance and exhaust flow.
