Description
The CARGRAPHIC 100CPSI Catalytic Converter Set is a motorsport-only exhaust upgrade engineered for maximum flow, performance, and reduced backpressure. Designed specifically for the Porsche 718 Cayman GT4 RS 4.0L and 718 Boxster Spyder RS 4.0L, this high-performance system replaces the factory catalytic converters with HD PE Motorsport 100CPSI cats and precision-engineered pipework for significant power and torque gains.
Built from SS304L lightweight stainless steel with mandrel-bent CNC construction, this set offers exceptional durability, reduced operating temperatures, and a freer-revving engine.
Note: This is an EXPORT VERSION – Motorsport use only. It is not OBD2 compliant and requires DME/ECU reprogramming.
Key Features:
- Performance Gains: +12KW (16PS) and +14Nm torque increase
-
Construction:
- 2.5" / 63.50mm over-axle pipe diameter
- Ø130mm housings with 70mm outlet flange diameter
- Flow-optimized filter insert for reduced backpressure
- CNC mandrel-bent SS304L stainless steel pipework for constant diameter
- Reinforced SS304L laser-cut flanges and brackets
-
