Buy BMW N54/N55 Downpipes at Palenon Performance
The BMW N54 engine is legendary, known for its twin-turbocharged performance. The N55, its successor, features a twin-scroll turbocharger that boasts a highly functional design but often restricts its true potential. We offer the BMW N54 and N55 downpipes for sale to unlock that potential!
The N54 engine has a twin-turbo setup that delivers explosive power along with a thrilling sound. However, it can be finicky and requires regular maintenance.
In contrast, the N55 offers a more refined and reliable experience thanks to its single twin-scroll turbocharger. While it may not deliver the same raw power as the N54, it offers better fuel economy.
Ultimately, the choice between the two engines depends on your priorities: raw power and tuning potential or refinement and reliability.
BMW N54 Downpipes
BMW N54 downpipes provide several advantages, such as enhanced torque, sound, and throttle response. They greatly reduce exhaust back pressure by eliminating the restrictive factory catalytic converters. The removal of these catalytic converters can result in a more aggressive and thrilling exhaust note.
N54 downpipes are specifically designed for BMW vehicles equipped with the N54 engine. This includes models like the E90 335i, E92 335i Coupe, E93 335i Convertible, E92 335is, E89 Z4 35i, E82, and 135i.
BMW N55 Downpipes
We offer both N55 PWG and EWG downpipes. The BMW N55 downpipes are similarly constructed from durable stainless steel, effectively preventing corrosion. Designed to enhance turbocharger efficiency, N55 downpipes feature reduced back pressure which enables quicker turbo spool-up and improved throttle response, resulting in a more responsive driving experience.
They are specifically designed for the BMW N55 engine and are compatible with models like the F10 535i, F10 535i xDrive, F11 535i, F11 535i xDrive, F30 335i, F30 335i xDrive, F31 335i, F31 335i xDrive, F32 435i, F32 435i xDrive, F33 435i, F33 435i xDrive, F36 435i Gran Coupe, F36 435i xDrive Gran Coupe, F12 640i, F12 640i xDrive, F13 640i, and F13 640i xDrive.
N55 PWG Downpipes
- The design will accommodate the smaller turbocharger found in earlier N55 models.
- The flow rate is optimized for the smaller turbocharger, focusing on efficient exhaust gas flow to maximize its potential.
- The diameter of the downpipe may be slightly smaller than EWG downpipes.
N55 EWG Downpipes
- These downpipes are designed to accommodate the larger turbocharger found in later N55 models.
- The flow rate is optimized for the larger turbocharger, allowing for greater exhaust gas flow and increased power potential.
- The diameter of the downpipe is typically larger than PWG downpipes to handle the increased flow rate.
BMW N54 vs N55 Catless Downpipes
N54 Catless Downpipes
Catless downpipes eliminate catalytic converters. But, users should be reminded that removing catalytic converters can dramatically make the vehicle non-compliant with emissions standards.
For the best result, you have to consider legal and environmental implications before installing catless downpipes. In many regions, using a vehicle with catless downpipes on public roads is illegal. So, consult local regulations before using a catless performance downpipe.
N54 catless downpipes require specific fitment for each N54-powered BMW model. Just, you have to consider factors like the vehicle's year, model, and transmission type. Additionally, we recommend professional installation to guarantee proper secure connections.
N55 Catless Downpipes
Increased horsepower and torque, improved throttle response, and a more aggressive exhaust note.
Significantly increased emissions, potential legality issues, and a louder, more intrusive exhaust sound that may not be suitable for daily driving.
Maximum performance gains, aggressive sound, and lightweight design.
Extremely loud exhaust note, potential heat shielding issues, and limited street legality.
Compatibility with Specific Models
N55 catless downpipes are compatible with the most used BMW models equipped with the N55 engine. Here is a list of the models: F10 535i, F10 535i xDrive, F11 535i, F11 535i xDrive, F30 335i, F30 335i xDrive, F31 335i, F31 335i xDrive, F32 435i, F32 435i xDrive, F33 435i, F33 435i xDrive, F36 435i Gran Coupe, F36 435i xDrive Gran Coupe, F12 640i, F12 640i xDrive, F13 640i, and F13 640i xDrive.

FAQs
Is the BMW N55 better than the N54?
The BMW N55 is generally considered more reliable than the N54. There are fewer reported issues and a simpler design is detected in N55. But, the N54 offers more tuning potential and a more engaging driving experience due to its twin-turbo setup.
Can you put the N55 turbo on the N54?
You can put an N55 turbo on an N54 engine, but it might require significant modifications to the engine and exhaust manifold. It's technically feasible, but we do not recommend it for those without extensive mechanical knowledge and experience.
Is the N55 engine forged?
No, the stock N55 engine is not forged. It comes with cast pistons and connecting rods. The best you can do is upgrade the N55 with forged internals. Most car tuners use this as a common modification to push the limits of their N55-powered vehicles.
What is the weak point of the N55 engine?
The N55 engine has the potential for rod bearing failure, especially in higher-mileage or heavily modified vehicles. That’s why we suggest drivers monitor oil pressure and change the oil and filter regularly to eliminate this risk. If you change the rod bearing, you can pretty much ensure the engine's longevity.
When did N55 replace N54?
The BMW N55 engine began production in 2009 and gradually replaced the N54 engine in various BMW models. There have been some overlaps in 2009 and 2010; but the N55 became the standard engine for most N54-powered models by 2011.
What size turbo is the N55?
The N55 engine uses a BorgWarner B03 turbocharger with a custom 62mm compressor wheel. From this setup, you can get a balance of performance and efficiency for delivering higher power and torque across the rev range.
How long can an N55 last?
If you maintain it properly, the N55 engine can easily last over 150,000 miles. Even many owners report exceeding 250,000 miles. To get that much-overclocked performance, you can conduct regular oil changes and coolant flushes.
