Product Description

The GrimmSpeed Staged Power Packages' greatest asset is the fact that every component is tested and intended to function flawlessly as a unit. Start with one of our fantastic Staged Power Packages based on your goals rather than trying to piece together parts from other vendors and hope that their design theories are compatible! With less restriction before and after the turbo, the GrimmSpeed Stage 2 Power Package is a well-rounded kit that increases power and torque production while also giving the car a more aggressive street presence with its 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 Version 2 J-Pipe replaces the extremely restrictive factory J-Pipe and catalytic converter with high-quality 3” diameter stainless tubing and a high-flow GESI catalytic converter.


The GrimmSpeed Stage 2 Power Package includes the same parts as the Stage 1 Package, but the J-Pipe considerably boosts the Turbocharger's performance. The Electronic Boost Control Solenoid pairs perfectly with the J-free-flowing Pipe's design for optimum boost control. The Version 2 J-Pipe expands the tubing diameter and swaps out the restricted catalytic converter for a high-flow GESI unit. As a result, the restriction after the turbo is reduced, the turbine's efficiency is raised, and the boost pressure and time to spool are also increased.


  • All GrimmSpeed Staged Power Packages require a proper tune.
