Diamond Eye KIT 4in CSTM TB HX40 DWNP 221040 DUAL AL 94-02 CUMMINS 5 9L NO WARRANTY FITMENT-CSTM KIT

This kit from Diamond Eye Performance includes everything you need to install a 4-inch turbo-back exhaust system on your 1994-2002 Cummins 5.9L. You'll get the downpipe, dual aluminum mufflers, and all the necessary piping to connect your turbocharger directly to the mufflers. This setup is designed to replace your factory exhaust system from the turbocharger back, offering a significant upgrade in flow and sound.

The system features a 4-inch diameter throughout, which is larger than the stock piping, allowing exhaust gases to exit the engine more freely. This improved flow can lead to better turbo spool and a more aggressive exhaust note. The dual aluminum mufflers are chosen for their durability and sound characteristics, providing a distinct tone for your Cummins. Because this is a custom-fit kit, it's intended for those who understand the specific needs of their build and are comfortable with custom installation procedures. It's important to note that this system is not CARB approved and cannot be shipped to California.

When installing this turbo-back system, you'll be removing the factory catalytic converter and muffler assembly. This is a direct replacement for the stock components from the turbocharger outlet back. Due to the custom nature of this kit and the lack of a manufacturer warranty, careful planning and potentially custom fabrication during installation might be required to ensure a perfect fit and optimal performance for your specific truck.
