This Sinister Diesel Power Package combines three of our most popular diesel performance parts for the 2001, 2002. 2003, 2004, 2005, 2006, and 2007 6.6L Chevy or GMC Duramax Diesel and includes the following:

This Power Package for the 6.6L Duramax starts with the Momentum HD Intake System from aFe. This high-performance cold-air intake replaces the restrictive factory air-box with a custom performance diesel intake that outflows the stock unit by over 32%. The Momentum HD is designed around a massive Pro 10R pre-oiled air filter that uses a unique interface to maximize intake-area and utilize the available air volume to produce an extra 24 horsepower and 44 pound-feet of torque. The unique one-piece sealed housing uses premium stainless T-bolt clamps to ensure that leaks are eliminated and your Duramax only receives the coldest air intake charge available.

In this Power Package, the Evolution CTS2 reprograms your vehicle's stock computer. It resides in the cab with one simple cable connection to the OBDII (diagnostic) port. The Evolution is used to save the stock files from the vehicle's computer and then upload the Edge calibrations into the vehicle's computer. This amazing product is available for both gas and diesel pickups and SUVs. This product comes with multiple power levels custom tuned by a whole team of engineers, and can be installed in minutes without ever popping the hood. The Evolution CTS2 greatly increases horsepower and torque. Not only does it re-tune your vehicle, it stays mounted in the cab and features real-time, monitoring of vital engine data.

The final part of the Sinister Diesel Power Package for the 6.6L Duramax is a Sinister Diesel 4” stainless steel exhaust. This fully-tuned exhaust system is designed to get you even more horsepower and torque by optimizing the flow of exhaust gasses out of the engine compartment of your truck. Each one of our Sinister Diesel Duramax exhausts are precision cut and mandrel bent from corrosion-resistant 409 stainless steel. In addition, each kit includes both an 18” long muffle and an 18” straight pipe so that you can easily choose the best sound for your truck, along with all the hardware you need to fit it to your truck. This is a great looking exhaust that is easy to install and because of its stainless construction, will last for the lifetime of your truck. Like every other Sinister Diesel exhaust kit, this kit for the Chevrolet and GMC Duramax is finished with a rolled and polished stainless-steel exhaust tip stamped with the Sinister Diesel logo.
