Description

Vehicle Fitment:

This kit is compatible with models equipped with an OEM-style 3-bolt flange that comes off the turbo direct pipe. However, it is not suitable for Cab & Chassis trucks and will not fit V-Band setups. Be sure to verify your truck’s fitment before purchasing.


Key Features:

  • T409 stainless steel piping: Durable, corrosion-resistant materials ensure long-lasting performance.
  • Downpipe-Back exhaust system: This setup provides maximum exhaust flow, enhancing power and efficiency.
  • OEM-Style 3-Bolt Flange: Ensures a proper fit with the factory turbo flange for a straightforward installation.
  • OE-Style Hangers: Makes the installation process smooth and secure, fitting seamlessly into factory positions.
  • No Muffler – Straight Pipe Design: Designed for maximum exhaust flow, ideal for competition applications.
  • No Bungs:  Where emissions-related components are removed it simplifies the design for off-road performance.

This race exhaust system lets you remove the catalytic converter and DPF filter easily. This upgrade significantly improves exhaust flow and boosts engine performance during off-road use. With the straight pipe design, your truck achieves maximum airflow, minimizing restrictions. This setup is ideal for competitive racing. However, you need race tuning for proper functionality, and remember, this system is strictly for off-road use only.

To achieve optimal performance, you should install and tune the system professionally. Always check your local laws before installing components designed for off-road use.
