Fits:
Porsche 996 3.6L 2001-05 (not Turbo and GT2)

Please note: These sport cats will make your car sound louder than with stock cats. If you have ,or intend to install sport silencers, you may find the car is a bit loo loud. We recommend to use one sport exhaust component if you are concerned about decibel levels.

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.

PORSCHE 996 Carrera 3.4L Replacement Cats made in grade 409 stainless steel.

Fits:
Porsche Carrera 3.4L

Our cat is made up of the following components:
  • Ceramic monolith of a honeycomb design to allow free air flow and maximum surface area, coated with precious metals to enable the conversion of gasses that pass through it
  • Interam matting to hold the monolith in place. The matting expands when exposed to heat to supply the pressure needed to keep the monolith secure
  • A grade 409 stainless steel can (or housing) to provide protection and enable the cat to be built into the exhaust system. 409 grade can contain upto 90% iron and will be prone to rust. It still has higher rust-resistant properties than mild steel.

About Catalyst / Bypass

Title: Porsche Exhaust Catalyst and Bypass Sports Catalyst: Technical Specifications and Benefits

Key Points:

Enhanced Performance: Upgrading your Porsche's exhaust catalyst or opting for a bypass sports catalyst can significantly improve performance by increasing horsepower and torque output. These aftermarket options are designed to optimize exhaust flow, resulting in improved engine efficiency and throttle response.

Enhanced Sound: An original Porsche or aftermarket exhaust catalyst can enhance the auditory experience of your vehicle. They offer a deeper, more aggressive exhaust note, providing a sportier sound that complements the performance-oriented nature of a Porsche.

Compliance with Emissions Standards: When purchasing an exhaust catalyst, it is crucial to consider its compliance with local emissions regulations. Porsche exhaust catalysts are engineered to meet strict emissions standards, ensuring that your vehicle remains environmentally friendly while delivering enhanced performance.

Quality and Durability: Original Porsche exhaust catalysts are manufactured to the highest standards, ensuring exceptional quality and durability. Aftermarket options from reputable brands also offer similar reliability, providing a long-lasting solution for your Porsche's exhaust system.

Easy Installation: Both original Porsche and aftermarket exhaust catalysts are designed to be direct replacements, making installation relatively straightforward. However, it is essential to follow the manufacturer's instructions or seek professional assistance to ensure proper fitment and optimal performance.
