Muffler for Nissan Note: how to choose, repair and replace it yourself

Muffler failure Nissan Note - a problem that every owner of this compact hatchback faces sooner or later. Corrosion, mechanical damage or simple wear of the metal lead to the appearance of holes, cracks and a characteristic “growling” sound under the hood. But don’t rush to go to a service station: many diagnostic and even replacement operations can be performed independently, saving up to 70% of the cost of work.

In this article we will look at all aspects of working with a muffler Nissan Note (including restyled models 2010–2023): from the selection of original and non-original spare parts to step-by-step instructions for dismantling and installation. We will pay special attention unique “weak points” of this model - for example, the tendency to rust at the place where the resonator is attached to the exhaust pipe, which is rarely discussed in standard manuals.

Signs of a faulty muffler: when to sound the alarm

The first symptoms of problems with the muffler on Nissan Note often go unnoticed until the situation becomes critical. Here are the key signals that should alert you:

• 🔊 Increased exhaust noise — instead of a muffled sound, the engine begins to “growl” or “shoot,” especially at high speeds.
• 💨 Exhaust smell in the cabin - a sign of a crack in the muffler or depressurization of connections (especially dangerous when driving with the windows closed).
• 🔥 Black marks on the body — soot settles near the rear bumper if the muffler lets gases through the cracks.
• 🛠️ Rattling or knocking noise - indicates a fallen internal partition or loose fastenings.

On Nissan Note first generation (E11, 2004–2010) most often suffers resonator - its thin metal burns out due to condensation. The second generation models (E12, 2013–2023) have a weak point - intake pipe corrugation, which cracks from vibrations. If you ignore these symptoms, the consequences can be more serious than just noise:

⚠️ Attention: Rusted muffler on Nissan Note with engine HR16DE may result in exhaust gases entering the interior ventilation system. This is fraught with carbon monoxide poisoning, especially during long trips in traffic jams!

To pinpoint the source of the problem, inspect the muffler on an overpass or pit. Please note:

• 🔍 Welding seams - they rust first.
• 🔧 Catalyst connections - often leak due to damaged gaskets.
• 💧 Condensate in banks - if gurgling is heard when rocking, a hole will soon appear.

Original vs analogue: which muffler to choose for Nissan Note

When replacing the muffler with Nissan Note The owner is faced with a dilemma: buy an original part or save on an analogue. Let's look at the pros and cons of each option.

Parameter	Original muffler (Nissan)	Analogue (Bosal, Walker, Asam)
Service life	5–7 years (with careful use)	3–5 years (depending on the manufacturer)
Price, rub.	12 000–20 000	4 000–9 000
Compliance	Full (EURO 5/6)	Partial (may not pass the eco-test)
Ease of installation	Perfect fit, no modifications	Adapters may be required
Warranty	1–2 years (at official dealers)	6–12 months (for trusted brands)

For Nissan Note with engines HR12DE And HR16DE original mufflers are supplied under the following article numbers:

• 📌 20560-4M00A — complete set (reception pipe + resonator + main muffler).
• 📌 20560-4M01A - for models with a catalyst under EURO 6.
• 📌 20580-4M00A — only the main muffler (can).

If your budget is limited, consider analogues from trusted brands:

• 🏆 Bosal (260-740) — best price/quality ratio, suitable for EURO 5.
• 🔧 Walker (21940) - reinforced design, but may require modification of fastenings.
• 💰 Asam (30614) - a budget option, but lasts no more than 3 years.

⚠️ Attention: When purchasing an analogue for Nissan Note with automatic transmission, check compatibility with the oxygen sensor (lambda probe). Some cheap mufflers do not have space for a second sensor, which will lead to an error P0420 on the dashboard.

If you operate your car in regions with an aggressive environment (salt on the roads, high humidity), we recommend that you pay attention to stainless steel mufflers from Remus or Sprint. They are 30–40% more expensive, but will last 2 times longer than standard ones.

Step-by-step instructions: how to remove and install a muffler on a Nissan Note

Replacing the muffler with Nissan Note - a task of average complexity that will require 2-3 hours of time and a minimal set of tools. The main thing is to prepare properly and follow the algorithm.

Required tools and materials:

• 🔧 Set of sockets (10, 12, 14 mm) with extension.
• 🔨 Hammer and chisel (for stuck nuts).
• 🔥 Gas torch or WD-40 (for rusty connections).
• 🛠️ New gaskets (item no. 20568-4M000 for connection with the catalyst).
• 🧲 Magnet on the telescopic handle (so as not to lose nuts in hard-to-reach places).

Work order:

1. Preparing the car. Drive Nissan Note onto an overpass or pit. If you work on jacks, be sure to secure the rear part on the supports. Disconnect the negative battery terminal - this will prevent short circuits when working with sensors.

2. Removing the heat shield. On models with HR16DE The screen is secured with four 10 mm socket head bolts. Remove it carefully so as not to bend it.

3. Disconnecting the muffler from the catalyst. The most problematic place here is the stuck nut on the clamp. Treat it with WD-40 and wait 10-15 minutes. If that doesn't help, use a gas torch (heat the nut until it turns red, then try to unscrew it).

4. Removing rubber hangers. Muffler on Nissan Note mounted on 3–4 hangers. Lubricate them with soapy water to make them easier to remove. If the rubber bands are torn, replace them with new ones (part number 20570-4M000).

5. Installing a new muffler. Start by attaching to the catalytic converter, then secure the hangers. Do not tighten the clamps all the way - leave 1-2 mm of play for thermal expansion.

Check all connections for tightness|Make sure the oxygen sensors are connected|Tighten the clamps, but do not over-tighten|Start the engine and check for leaks-->

Pay special attention connecting the exhaust pipe to the catalyst. On Nissan Note Parts of the old gasket often remain here, which can cause air leaks. Clean the surfaces with a wire brush and apply a thin layer of high temperature sealant (such as Permatex Ultra Copper).

⚠️ Attention: After replacing the muffler with Nissan Note with the system Eco Mode an error may appear P0420 (low catalyst efficiency). This is normal - the error will reset after 2-3 “cold start → warm up” cycles. If not, check the connection of the second lambda probe.

What to do if the clamp nut does not unscrew?

If WD-40 and a torch don't help, try the following method:

1. Place the socket and extension onto the nut.

2. Hit the extension cord with a hammer (not the head!) 2-3 times.

3. Turn the key sharply counterclockwise.

In 90% of cases this breaks off the rust. If the nut breaks, you will have to cut off the clamp with a grinder and install a new one (part number 20565-4M000).

Muffler repair without replacement: when possible

Not always a crack or hole in the muffler Nissan Note means mandatory replacement. If the damage is not critical (up to 2–3 cm), you can try to repair the part. Let's look at proven methods.

1. Cold welding (for small cracks):

• 🔧 Suitable for cracks up to 1 cm on a resonator or jar.
• 🧪 Use epoxy resin compounds with a metal filler (for example, Abro Steel).
• ⏳ Hardening time - 24 hours (do not operate the car during this time!).

2. Semi-automatic welding:

• 🔥 Effective for holes up to 2 cm, but requires removal of the muffler.
• 🛠️ Use wire ER70S-6 and gas Ar/CO2.
• ⚠️ After welding, be sure to paint the seam with heat-resistant paint (withstands up to 600°C).

3. Bandage made of metal tape:

• 🌀 Suitable for temporary repair of corrugation or joints.
• 🔧 Use ribbon Dexsil or Rescue Tape with silicone coating.
• ⏰ Service life - up to 6 months (depending on load).

On Nissan Note most often repaired intake pipe corrugation And resonator welds. For example, if a crack appears at the mounting location of the suspension bracket, it can be welded without complete replacement. However, there are cases when repairs are useless:

• 🚫 Through corrosion of the can (holes larger than 3 cm).
• 🚫 Destruction of internal partitions (the muffler rattles when shaken).
• 🚫 Cracks near the catalyst (high temperatures will quickly destroy the patch).

If you decide to repair the muffler yourself, follow the rules: any patch must cover the damage by at least 2 cm on all sides. For example, for a hole with a diameter of 1 cm, cut a patch measuring 5x5 cm.

How to extend the life of a muffler: prevention and care

Muffler service life Nissan Note directly depends on operating conditions and regular maintenance. Here are proven ways to delay replacement:

1. Anti-corrosion treatment:

• 🧴Apply to the outer surface of the muffler heat-resistant anticorrosive (For example, Dinitrol 479) every 6 months.
• 🔥 Before processing, warm the muffler to 50–60°C - this will improve adhesion.
• 🚫 Avoid bitumen-based compounds - they melt at high temperatures.

2. Proper washing:

• 🚿 Do not wash the engine and muffler in a high-pressure car wash - water will get inside and accelerate corrosion.
• 💧 After washing in winter, dry the muffler by driving 5–10 km at high speeds (3000–3500 rpm).

3. Condensate control:

• 💧 Every 2-3 months, drill a hole with a diameter of 2-3 mm at the bottom point of the resonator to drain the condensate.
• 🔧 Use a metal drill with titanium coating - it keeps its sharpness longer.

4. Gentle riding style:

• 🚗 Avoid sudden starts and braking - this creates excess pressure in the system.
• 🛣️ Reduce speed on uneven roads - impacts shorten the service life of the muffler hangers.

For Nissan Note With a mileage of more than 100,000 km, we recommend checking every 20,000 km:

• 🔍 Condition of rubber hangers - they become tanned and crack.
• 🔧 Tightening the clamps — vibrations weaken the fastenings.
• 💨 Exhaust color - Black smoke indicates a rich mixture, which accelerates corrosion.

If you often drive off-road or in rainy weather, install additional muffler protection - metal screen or plastic shield. This will protect the part from impacts and reduce the ingress of dirt.

Typical mistakes when replacing a muffler on a Nissan Note

Even experienced car owners make mistakes when working with the exhaust system. Nissan Note. Here are the most common mistakes and how to avoid them:

1. Ignoring gaskets:

• 🚫 Error: Installing a new muffler on old gaskets.
• ✅ Solution: Always change gaskets (part no. 20568-4M000) and apply graphite lubricant to them.

2. Re-stretching the clamps:

• 🚫 Error: Tightening the clamps “all the way”, which leads to deformation of the flanges.
• ✅ Solution: Tighten the clamps with a torque wrench with a force of 25–30 Nm.

3. Incompatibility with sensors:

• 🚫 Error: Purchasing a muffler without a seat for a second lambda probe.
• ✅ Solution: Check that there is a hole for the sensor (on Nissan Note with HR16DE it should be after the catalyst).

4. Neglecting alignment:

• 🚫 Error: Installing a muffler without alignment to the axis of the exhaust system.
• ✅ Solution: Before tightening the clamps, make sure that all elements are aligned (without distortions).

5. Savings on fastenings:

• 🚫 Error: Using old rubber hangers.
• ✅ Solution: Change the hangers every time you replace the muffler (they are inexpensive - about 200 rubles apiece).

Another typical problem is incorrect assembly sequence. For example, if you first fix the muffler on hangers and then connect it to the catalyst, it will be difficult to align the flanges. Correct order:

1. Connect the muffler to the catalyst and tighten the clamp.
2. Hang the muffler on rubber hangers.
3. Adjust the position so that there is no tension.

If after replacing the muffler with Nissan Note a whistling or hissing sound appears, most likely the tightness of the connection with the catalyst is broken. Check:

• 🔍 Availability of gasket and its integrity.
• 🔧 Uniform tightening of the clamp nuts.
• 💨 No cracks on the catalyst flange.
