Nissan Tiida is a popular compact car valued for its reliability and efficiency. However, even with such cars, key elements of the exhaust system wear out over time, and exhaust pipe (aka "standard spider" or "catalyst pipe") is one of the first parts that require attention. This part of the system directly affects engine dynamics, fuel consumption and compliance with environmental standards.
Owners Tiida (especially with motors HR16DE And MR20DE) often encounter problems: from cracks and burnouts to a clogged catalyst. But how can you tell if a pipe has failed? Is it worth buying the original or can you save money on analogues? And most importantly, how to replace it yourself without damaging the car? In this article we will sort everything out, with photos, diagrams and unique nuances specifically for Tiida 2007–2017.
What is a exhaust pipe and why is it needed in Nissan Tiida
The exhaust pipe (aka exhaust manifold with integrated catalytic converter) is the first element of the exhaust system after the engine. Her tasks:
- 🔥 Removal of hot gases from cylinders (temperatures up to 900°C!).
- 🌿 Exhaust cleaning through the catalytic converter (in models for Euro-4/Euro-5).
- 🎯 Flow optimization to reduce back pressure and improve motor efficiency.
- 🔊 Noise reduction at the initial stage (together with the resonator).
B Tiida the exhaust pipe is combined with catalyst (unlike many foreign cars, where they are separated). This simplifies the design, but complicates repairs: if the catalyst fails, the entire pipe has to be replaced. By the way, in versions for Japan And Asia (without Euro-5) the catalyst is often missing - instead there is a regular corrugation.
On Tiida J10 (2007–2011) and J11 (2011–2017) pipes are visually similar, but have different catalog numbers and fasteners. For example, on HR16DE (1.6 l) the part with art. no. is used. 20620-4M000, and on MR20DE (2.0 l) — 20620-6N000. They cannot be confused: the diameters of the flanges and the location of the oxygen sensors are different.
On Tiida With an automatic transmission, the exhaust pipe lasts longer than with a manual transmission due to smoother loads on the engine. But if the car is often driven for short trips (the engine does not warm up completely), the catalyst clogs faster.
Signs of a problem: when is it time to change the pipe
Symptoms of a problem with the exhaust pipe on Tiida often confused with engine or fuel system malfunctions. Here exact signs, that this is exactly what’s wrong with her:
- 🚗 Power drop during acceleration (especially at rpm 2500–3500). It feels like the car is being “held by the tail.”
- 🔊 Loud roar under the hood — a metallic sound, like a “hole in the muffler,” but coming from the front.
- ⚠️ Check Engine with errors
P0420(“low catalyst efficiency”) orP0430. - 💨 Smell of sulfur or rotten eggs in the cabin - a sign of destruction of the catalyst.
- 🔥 Visible cracks or rust on the pipe (inspect through a mirror or on a lift).
On Tiida With a mileage of 150 thousand km or more, the catalyst often “dies” due to natural wear. But there are also accelerated reasons:
- 🛢️ Bad fuel (additives or high sulfur content destroy the catalyst honeycomb).
- 🔧 Faulty spark plugs/misfires — unburned fuel burns out in the pipe, overheating it.
- 🚗 Riding through puddles after the engine warms up (sharp temperature changes lead to cracks).
- Up to 100,000 km
- 100,000–150,000 km
- 150,000–200,000 km
- More than 200,000 km
⚠️ Attention: If on Tiida after replacing the pipe it caught fireCheck Enginewith an errorP0130(oxygen sensor), most likely you forgot to move the old lambda probe or damaged its connector. On motorsHR16DEthe sensor is welded into the pipe, and onMR20DE- mounted on a flange.
Original vs analogues: what to choose for replacement
Original exhaust pipe from Nissan (art. 20620-4M000 for 1.6 and 20620-6N000 for 2.0) costs from 25,000 to 40,000 rubles. The price is justified by the quality of the metal and catalyst, but is not always appropriate. Let's look at the alternatives:
| Part type | Manufacturer | Article | Price, ₽ | Pros | Cons |
|---|---|---|---|---|---|
| Original | Nissan | 20620-4M000 |
25 000–40 000 | 2 year warranty, perfect fit, long service life | Expensive, may be out of stock |
| Analogue (with catalyst) | Bosal, Walker | BO 206-204, WK 56373 |
12 000–18 000 | Good quality, certified for Euro 5 | Mounts may not fit (check before purchasing!) |
| Universal (without catalyst) | Fox, MG-Race | — | 5 000–10 000 | Cheap, suitable for tuning | Will not pass inspection, requires ECU flashing |
| Used (contract) | — | — | 3 000–8 000 | Low price | Risk of hidden cracks, short service life |
For most owners Tiida optimal choice - analogues from Bosal or Walker. They are 2 times cheaper than the original, but meet Euro-5 standards. If the car is older than 2012 and does not meet eco-standards, you can consider universal pipe without catalyst, but you have to:
- 🔧 Install lambda probe decoy (mechanical or electronic).
- 💻 Reflash the ECU for Euro-2 (costs ~10,000 ₽).
- 📝 Prepare for problems during technical inspection (in some regions they check the presence of a catalyst with an endoscope).
What happens if you drive with a damaged catalyst?
The catalyst honeycombs can crumble and enter the cylinders through the EGR valve (if there is one), which will lead to scoring on the walls and expensive engine repairs. In addition, the fragments will clog the second lambda probe, and it will also have to be replaced (~8,000 ₽).
Step-by-step instructions for replacing the exhaust pipe
Replacing the pipe with Tiida - a task of medium complexity. If you have tools and a viewing hole, you can do it in 2–3 hours. Here's what you'll need:
- 🔧 Set of sockets (10, 12, 14 mm) and extension.
- 🔨 WD-40 or similar “liquid key”.
- 🔥 Gas burner (for stuck nuts).
- 🛠️ New flange gasket (art.
14045-4M000). - 🧤 Gloves and glasses (rust will fall off the old pipe).
Work order:
- Removing protection. Remove the metal tray protection (4 bolts x 10 mm).
- Disconnecting sensors. Disconnect the lambda probe connectors (carefully so as not to break the chips!).
- Unscrewing the flange. First loosen the nuts on the manifold flange (14 mm), then on the connection to the resonator (12 mm).
- Removing the pipe. Carefully lower it down, avoiding hitting the tray.
- Installing a new one. Check that the gasket lies flat and without distortion.
- Reassembly. Tighten the nuts crosswise to avoid flange deformation.

⚠️ Attention: On Tiida with motor MR20DE (2.0 L) downpipe is attached to the turbine (if equipped). When dismantling, do not pull it down - first unscrew the turbine bracket, otherwise you may tear the intercooler pipes.
After replacement:
- 🔧 Check for leaks - Start the engine and inspect the connections for leaks (listen for hissing).
- 💻 Reset errors scanner (for example, ELM327). Error
P0420should disappear after 2-3 warm-up cycles. - 🚗 Drive 50–100 km and evaluate the dynamics - if the acceleration is faster and the sound is quieter, the work has been done correctly.
Tuning and modifications: what can be done with the exhaust pipe
Many owners Tiida want to improve dynamics or exhaust sound. Here are the popular modifications of the exhaust pipe:
- 🏁 "Spider" 4-2-1 — Replacing the standard pipe with a sports manifold. Gives +5–7 hp. at high speeds, but requires ECU adjustment.
- 🔊 Removing the catalyst + installation of a flame arrester. Cheaper than the original, but noisier and not environmentally friendly.
- 🔥 Ceramic coating — protects the pipe from rust and reduces heat loss (relevant for turbo versions).
- 🛠️ Corrugated inserts — prevent cracks due to vibrations (useful for cars with rigid suspension).
On Tiida J11 with motor HR16DE often install a "spider" from Nissan Juke (art. 20620-3MU00) - it fits the flanges and gives an increase in dynamics. But there are nuances:
- The fastenings need modification (you will have to weld a new bracket).
- It is necessary to reconfigure the ECU for the changed exhaust (otherwise there will be an error
P0420). - The sound becomes louder by 20–30% (not everyone likes it).
On naturally aspirated engines (HR16DE) tuning the exhaust pipe gives a minimal increase in power (1–3 hp). The main effect is improved sound and reliability. On turbo versions (MR20DE) the increase can reach 10–15 hp. by reducing back pressure.
Common replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when working with the exhaust pipe. Tiida. Here top 5 misses and how to prevent them:
- Using an old gasket.
The flange gasket is disposable! When used repeatedly, it sags and gases leak. Always take a new one (art.
14045-4M000). - Retightening the nuts.
The flange tightening torque is 40–50 Nm. If you overtighten, the flange will become deformed and the pipe will suck in air.
- Ignoring oxygen sensors.
On Tiida with Euro-5 there are two lambda probes: upper (before the catalyst) and lower (after). If you forget to connect the lower one, the ECU will show an error
P0141. - Buying a pipe without checking the article number.
Pipes for
HR16DEAndMR20DEThey are similar in appearance, but have different flange diameters. Specify the vehicle's VIN when ordering! - Work without removing protection.
Without removing the metal pan protection, you will not be able to reach the nuts on the resonator. Don’t be lazy to remove it - you’ll save time.
Another typical problem is sticking of nuts. On Tiida after 100 thousand km, threaded connections often rust. To unscrew them without cutting:
- Apply liberally with WD-40 and wait 30-60 minutes.
- Use a socket with an extension for more leverage.
- If it doesn’t work, heat the nut with a gas burner (the metal will expand and the rust will come off).
Cost of service work vs independent replacement
Prices for replacing the intake pipe in services vary depending on the region and the complexity of the work. Here are the estimated prices for Tiida:
| Type of work | Cost, ₽ | Time | Notes |
|---|---|---|---|
| Replacing the pipe (without removing the protection) | 2 500–4 000 | 1.5–2 hours | If the nuts are not stuck |
| Replacement with cutting/welding | 5 000–8 000 | 3–4 hours | If the pipe is rusted to the manifold |
| Spider installation 4-2-1 | 6 000–10 000 | 4 hours | Includes ECU tuning |
| Diagnostics after replacement | 1 000–1 500 | 30 minutes | Checking for errors and leaks |
Self-replacement will only cost the cost of parts (12,000–20,000 rubles for an analogue) and tools (if they are not available). Savings - up to 15,000 ₽. However, consider the risks:
- 🔧 Thread failure on the manifold (repair by welding will be required).
- 🔥 Damage to sensors (lambda probes are fragile, the cost of a new one is ~8,000 rubles).
- 🚗 Gas leak due to incorrect installation of the gasket.
If you have never worked on an exhaust system, it is better to entrust the replacement to professionals. But if you have experience and tools, self-repair is quite possible.
On Tiida with a mileage of more than 200 thousand km, when replacing a pipe, it is recommended to simultaneously check and replace the exhaust system supports (art. 20710-4M000). They often break and the new pipe will vibrate.
FAQ: Answers to frequently asked questions
Is it possible to drive with a crack in the exhaust pipe?
Short-term - yes, but it is fraught with:
- Exhaust gases entering the cabin (risk of CO poisoning).
- Overheating of adjacent parts (for example, fuel pipes).
- Excessive noise, which can lead to a fine (under Part 1 of Article 12.5 of the Administrative Code - 500 ₽).
If the crack is small, it can be temporarily sealed, but it is better to replace the pipe.
How to check if the catalyst is clogged?
There are 3 ways:
- Visually. Remove the pipe and shine a flashlight through the honeycomb - if the light does not pass through, the catalyst is clogged.
- By pressure. Insert the pressure gauge into the location of the oxygen sensor. Pressure above 0.3 kgf/cm² at 2500 rpm is a sign of blockage.
- By dynamics. If the car accelerates poorly after 3000 rpm, but idles smoothly, the catalyst is to blame.
Which is better: original, analogue or universal pipe?
The choice depends on the goals:
- Original - if you want reliability and are not willing to take risks.
- Analogue (Bosal, Walker) — the best price/quality balance.
- Universal - only for tuning or if the car does not pass environmental inspection.
For most owners Tiida The best option is an analogue one - it is 50% cheaper than the original, but lasts almost as long.
Do I need to flash the ECU after replacing the pipe?
Only in two cases:
- If you installed a pipe without catalyst (you need to disable the error
P0420). - If you set "spider" 4-2-1 (correction of fuel maps is required).
When replacing with a similar pipe (with a catalyst), firmware is not needed.
How long does the exhaust pipe last? Tiida?
Service life depends on operating conditions:
- 100,000–150,000 km - when driving on high-quality fuel and without overheating.
- 50,000–80,000 km — if you often drive through puddles or use bad gasoline.
- 200,000+ km - possible only on the original pipe with careful operation.
On motors MR20DE (2.0 l) pipe lasts longer than HR16DE (1.6 L), due to lower exhaust temperatures.
