Exhaust Nissan Note

The exhaust system on the Nissan Note serves several key functions: evacuating engine gases, reducing noise, lowering temperature and emissions, and optimizing engine performance and fuel consumption. The system includes components like the rear muffler, catalytic converter, DPF (Diesel Particulate Filter for diesel models), and lambda sensor which regulate air-fuel mix and emissions.

The primary components include:

• Rear muffler - absorbs noise and releases final exhaust gases.
• Catalytic converter - reduces harmful emissions such as CO, NOx, and hydrocarbons.
• DPF (Diesel Particulate Filter) for diesel models - traps particulate matter.
• Rubber mounts and mounting kits - support and reduce vibrations.
• Lambda sensor - monitors and adjusts air-fuel ratio for optimal emission control.

Regular inspection is advised to maintain these components and ensure proper exhaust system function.

Common symptoms and possible causes include:

• Exhaust odor inside the vehicle - often due to broken joints or leaks, especially in diesel models.
• Low DPF pressure - a sign of DPF malfunction in diesel variants with higher mileage.
• Engine power loss with check engine light - usually related to faulty lambda sensors or exhaust issues.
• Vibrations and excessive noise under the car - caused by leaks or wear in the rear muffler.
• Black smoke and increased fuel consumption - related to exhaust line leaks.

Neglecting these issues may result in fuel overconsumption, excessive pollution, fines, or health risks from CO exposure.

Maintenance recommendations for key parts:

• Rear muffler: Inspection every 60,000 to 80,000 km.
• Catalytic converter: Check every 100,000 km for proper function and emissions standard compliance.
• DPF (diesel only): Monitor pressure; perform highway runs for regeneration and use OBD diagnostics if needed.
• Rubber mounts and kits: Replace if worn or damaged to avoid vibrations and structural stress.

General exhaust system inspections every 20,000 km or at each service are advised.

Yes, replacing the rear muffler on models like the E11/NE11 (2005-2013) can be done as a DIY task by following safety precautions and the recommended procedure:

• Lift the vehicle safely with a jack or use a repair pit.
• Clean and loosen the clamp securing the muffler.
• Support the muffler with a hydraulic jack before detaching mounts.
• Remove rubber supports with care; gentle leverage tools might be needed.
• Detach the muffler from the exhaust pipe using a crowbar and hammer if necessary.
• Inspect and clean mounting seats; replace rubber mounts if worn.

Use proper tools such as a 13 mm socket, ratchet, WD-40, crowbar, hammer, and wire brush. Always ensure the engine is off and the vehicle is securely supported. Variations may exist depending on motorization (e.g., 1.4 LPG).

Recommended maintenance practices include:

• Perform regular complete exhaust system inspections every 20,000 km or at each vehicle service.
• Maintain the catalytic converter and check its condition at approximately 100,000 km.
• Ensure proper DPF regeneration on diesel models by making regular highway drives; diagnose any low pressure warnings promptly.
• Replace rubber mounts and seals if deterioration is visible to avoid vibration damage.
• Seek professional garage service when unsure; authorized centers offer diagnostics and repairs.

Proper maintenance helps ensure emission standards are met and protects engine performance and fuel efficiency.

If you notice exhaust odor inside the vehicle or unusual noises such as vibrations or loud sounds underneath, it could indicate leaks or damaged components like the rear muffler or faulty joints, especially in diesel versions.

• Stop driving and have the exhaust system inspected promptly to avoid the risk of toxic CO fumes entering the cabin.
• Check for broken joints or cracked pipes which can cause leaks and odors.
• Replace damaged rubber mounts or muffler parts to restore proper sealing and noise damping.
• Seek professional diagnostics if the check engine light is on or if you experience power loss, as this may relate to lambda sensor or DPF issues.

Early detection can prevent increased fuel consumption, pollution fines, and health hazards.

For authentic, high-performance exhaust parts including catalytic converters and DPFs for Nissan Note vehicles, choose reputable suppliers that offer original manufacturer quality components. These parts comply with European standards (E24-103R certification) and deliver durability and optimal emission control.

• Ensure components are made from quality stainless steel (e.g., INOX 409) with advanced monolith technology.
• Confirm compatibility by providing your vehicle's precise model and engine details or VIN to get exact fitting parts.
• Consider suppliers that provide technical support and installation guides to correctly replace exhaust components.
• Check warranty terms and return policies for added assurance.

Properly sourced exhaust parts contribute to sustained vehicle performance, emissions compliance, and safe driving.
