BMW N55 Downpipe with 200-CPI Metal Catalytic Converter

This BMW N55 downpipe with a 200-CPI metal catalytic converter was developed for performance-oriented vehicles with an N55B30 turbo engine and an electronically controlled wastegate.

The pipe diameter of Ø 76 mm allows for improved exhaust flow compared to a more restrictive stock exhaust system. This reduces exhaust backpressure and relieves the turbocharger, particularly in performance-tuned vehicles.

When used in conjunction with appropriately tuned engine software, the downpipe can help maximize the performance potential of the N55 engine.

Depending on the vehicle, software version, and exhaust monitoring system, an adjustment to the engine software or the monitoring of the after-treatment lambda sensor may be necessary after installation.

High-quality stainless steel construction

The downpipe is made of stainless steel and is designed to withstand the high thermal stresses in the turbocharger area.

The connection flanges are intentionally made of steel. This reduces the risk of the flanges warping at high temperatures.

The flange surfaces are additionally designed to ensure the cleanest and tightest possible connection to the exhaust system.

The downpipe features a total of 4 welded lambda sensor connections with M18x1.5 mm threads.

PWG or EWG – an important distinction for the BMW N55

Two different wastegate systems were used in the BMW N55:

PWG – Pneumatic Wastegate

The earlier N55 version features a pneumatically or vacuum-controlled wastegate.

The wastegate actuator can be identified by a typical round vacuum port.

For certain models, such as the BMW M135i and BMW 335i, this version is primarily found on vehicles with a production date up to approximately 07/2013.

This downpipe is not intended for the PWG version.

EWG – Electronic Wastegate

The later N55 model features an electronically controlled wastegate with an electric actuator mounted directly on the turbocharger.

This version was used in various N55 models starting approximately from the production period 07/2013.

For vehicles such as the BMW M235i and BMW 435i, the later EWG variant is generally used.

This downpipe is designed for the N55-EWG version.

Why This Distinction Is Important

PWG and EWG turbochargers differ not only in terms of wastegate control.

The design and connection of the downpipe to the turbocharger also differ. A downpipe for the PWG version cannot therefore be used without further adaptation on a vehicle with an EWG turbocharger—and vice versa.

The engine code N55B30 alone is therefore not sufficient to unambiguously determine the correct downpipe.

Compatible with the following BMW N55 models with EEC

Depending on the production date and vehicle model, this product is compatible with, among others:

  • BMW M135i F20 / F21 – EEC version, generally from approx. 07/2013 onward

  • BMW M135i xDrive F20 / F21 – EEC version

  • BMW M235i F22 / F23 – EEC version

  • BMW M235i xDrive F22 / F23 – EEC version

  • BMW 335i F30 / F31 / F34 – EEC version, generally from approx. 07/2013 onward

  • BMW 335i xDrive F30 / F31 / F34 – EEC version, generally from approx. 07/2013 onward

  • BMW 435i F32 / F33 / F36 – EEC version

  • BMW 435i xDrive F32 / F33 / F36 – EEC version

ATTENTION – please check before ordering

This downpipe is intended exclusively for vehicles with an electronic wastegate (EWG).

Please be especially careful with vehicles manufactured between June 2013 through August 2013; do not rely solely on the initial registration date or the model year.

The actual production date and the turbocharger/wastegate configuration installed are decisive.

The easiest way to tell them apart visually:

PWG: Round pneumatic vacuum port on the turbocharger
EWG: electric servomotor / electronic actuator module on the turbocharger

If you are unsure, we recommend checking the wastegate configuration based on your vehicle or VIN before placing your order.

Note

Installing a sport downpipe may affect exhaust performance, noise levels, and vehicle registration. Please observe the legal regulations applicable to your vehicle and your country.
