Exhaust catalytic converters 200 Cell. 2.5" 63mm

designtek

Fits:
Porsche 997.1 Carrera 3.6 / 3.8 2005-08

These are a unique design optimised for sound and power with a larger bore 2.5" allowing greater gas flows.
These 63.5MM larger bore, powerful cats boast a sportier sound than OE and taper down to meet the original 54mm piping, making them an easy fit replacement for OE. The difference in performance is really felt.

The part comes with all joiners and clamps so fitment is a non-issue. The cats used are high quality, German-manufactured 200 Cell 40G loaded cats and the X-Pipe fabrication element is professionally mandrel bent for maximal gains and optimal flow.

Please note: Sports catalytic converters or bypass pipes do have type approval and may not be legally installed on vehicles manufactured after 1st March 2001. They can not be used on a public road and are not MOT compliant, they are designed for race and track cars only.

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.
