The beauty of the GrimmSpeed Staged Power Packages is that all of the included components were designed and tested to work well together as a complete system. Instead of piecing together parts from many different manufacturers and hoping that their design theories are compatible, consider starting with of Grimmspeed's excellent Staged Power Packages based on your goals! The GrimmSpeed Stage 2 Power Package is a well-rounded kit, offering increased power and torque output thanks to reduced restriction before and after the turbo, as well as a more aggressive street presence thanks to the intake and exhaust tones.
The upgraded GrimmSpeed 3-Port Boost Control Solenoid offers more accurate and more responsive boost control and is a must when having your vehicle professionally tuned. The GrimmSpeed Intake adds an additional performance increase by reducing pre-turbo restriction, which allows your turbo to build boost more quickly and more efficiently. The GrimmSpeed J-Pipe replaces the extremely restrictive factory J-Pipe and catalytic converter with high quality 3” diameter stainless tubing and a high-flow catalytic converter.
The free-flowing design of the J-Pipe offers superior boost control, and is the perfect complement to the Electronic Boost Control Solenoid. Over stock, the J-Pipe replaces a restrictive catalytic converter with a high flow unit as well as increases the tubing diameter. The result is a decrease in restriction after the turbo, an increase in turbine efficiency, and will further decrease time to spool as well as increase boost pressure.
- Hybrid cold air/short ram design - Combines the advantages and eliminating the negatives of both traditional intake designs
