Downpipe suited to LHD models - can fit RHD with some modification.

The beauty of the GrimmSpeed Stage 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 one of our excellent power packages designed to work as one unit.

The GrimmSpeed Stage 3 Power Package has everything you need to capture the power you are looking for in your 2015+ Subaru STI. 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 Catted Downpipe replaces the restrictive OEM Downpipe and makes your engine exhaust gas flow smoother and faster. 

It's important to note that all GrimmSpeed Staged Power Packages require a proper tune.

Stage 3 Package Features:

  • Decrease Spool Time - Lower intake restriction and better boost control
  • Plug and Play into OEM Harness - No splicing wires like other BCS solutions
  • High-Density, High-Flow Intercooler Core - Optimizes heat transfer and minimizes flow restriction for turbo Subarus
  • Hybrid Cold Air/Short Ram Design - Combining the advantages and eliminating the negatives of both traditional intake designs
  • Custom reusable high flow air filter - Integrated velocity stack entrance smooths incoming air
  • Stainless Steel Construction - The downpipe is constructed of high grade 304L SS for corrosion resistance and durability
  • Made in the USA - Right here in Minnesota

Performance:

The GrimmSpeed Stage 3 Power Package features the same components of the Stage 1-2 Packages, but further increases the performance of the engine with the inclusion of the GrimmSpeed Top Mount Intercoooler, Splitter and Heatshield.
