The Darkside Developments 3″ or 2.5″ stainless steel DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) delete kit offers a comprehensive solution for removing factory emissions controls on US-spec CJAA 2.0 diesel engines. This comprehensive guide explores the benefits, components, and considerations of this performance-enhancing upgrade.
Understanding the CJAA DPF Delete Kit
This kit provides a direct replacement for the factory DPF and EGR systems, improving exhaust flow and potentially boosting engine performance. Crafted from durable 316 aircraft-grade stainless steel, it’s designed for longevity and maximum performance. The kit is available with options for a 2.5″ or 3″ secondary catalytic converter delete pipe, allowing for further customization of your vehicle’s exhaust system. Choosing the 3″ downpipe is generally recommended for optimal flow.
Kit Components and Installation
The Darkside Developments Cjaa Dpf Delete kit includes:
- 3″ or 2.5″ Stainless DPF Delete Downpipe: The core component replacing the restrictive factory DPF.
- EGR Delete Kit with Race Pipe: Eliminates the EGR system, preventing recirculation of exhaust gases.
- Downpipe Gasket: Ensures a proper seal between the downpipe and the exhaust system.
- Slip Joint Exhaust Reducer with V-Band Fitting (if ordered without secondary CAT delete): Adapts the downpipe to the existing exhaust system.
- 2.5″ or 3″ Secondary CAT Delete Pipe (optional): Removes the secondary catalytic converter for further flow improvement.
- Straight Connector for EGR Cooler Delete: Facilitates removal of the EGR cooler.
Tuning and Performance Upgrades
While the DPF and EGR delete kit itself can improve performance, a custom ECU remap is crucial. This remap adjusts the engine’s software to accommodate the removed emissions components, preventing fault codes and ensuring optimal performance. Darkside Developments offers remote tuning solutions via their Powergate Unit for seamless integration with the delete kit.
Beyond tuning, Darkside Developments offers further performance upgrades for CJAA engines, including a CP3 fuel pump upgrade kit and a 200 BHP turbocharger upgrade. The CP3 pump offers increased fuel flow and reliability compared to the stock CP4.1 pump, while the turbocharger upgrade significantly increases power output.
Vehicle Compatibility and Legal Considerations
The CJAA DPF delete kit is compatible with various US-spec Volkswagen and Audi models equipped with the CJAA or CBEA engine code, including:
- Audi A3/S3 (CBEA)
- VW Beetle (CJAA)
- VW Golf (CJAA)
- VW Jetta (CBEA/CJAA)
- And more… (Refer to the full vehicle compatibility list on the Darkside Developments website)
It’s crucial to understand the legal implications of DPF delete in your region. Removing emissions equipment may violate local laws and regulations regarding on-road vehicle use. This modification is typically intended for off-road or track use only.
Conclusion
The Darkside Developments CJAA DPF delete kit offers a potential performance boost for US-spec 2.0L diesel engines. Combined with ECU tuning and optional performance upgrades, it can significantly enhance your vehicle’s capabilities. However, always remember to comply with local laws and regulations regarding emissions equipment. Consult with Darkside Developments or a qualified automotive professional for guidance on installation and tuning options. Always prioritize responsible and legal modifications.
