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 they're design theories are compatible, consider starting with one of our 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.
