Product Information
Porsche 996 Carrera 2 Carrera 4
Reduced cell catalytic converters

Fits
Porsche 911 C2 and C4 - 3.4Ltr (1997-2001)
Porsche 911 C2 and C4 - 3.6Ltr (2002-2004)
This may cause the check engine light to come on
The component is perfectly interchangeable with the original components, following the instructions in the constructor's workshop manual
RACETRACK USE ONLY
These components are designed and developed for racetrack use and to maximise the car's performance. They are not street legal and must be installed by professionals in the sector
REDUCED CATALYTIC CONVERTER - 200 CELLS
Race catalytic converters have fewer cells than standard factory systems. This reduces exhaust back pressure while still maintaining the operation of the catalytic converter, and improves performance and sound
ECU REMAPPING - ENGINE LIGHT
Replacement or removal of components such as catalytic converters, GPFs and electric actuators may cause the engine warning light to come on. In this case, the installer must reprogram the software to eliminate the light
MATERIAL - AISI 304 STAINLESS STEEL
AISI 304 STAINLESS STEEL
A choice stainless steel ideal for aggressive environments where combustion emissions can cause serious chemical corrosion on other types of metal
MAIN PIPE DIMENSION - 54mm
This is the diameter of the main pipe of the exhaust system
NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.
For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.
If you are located outside the UK, please check your local laws and regulations to ensure compliance.
