Product Description
COBB Tunning 612X42 Staged Power Packages 04-07 Subaru Impreza STi
This is where to start your quest for additional power and response from the STI. Included in the Stage 1 kit is the highly regarded AccessPORT which is used to reprogram the factory engine computer, unlocking an additional 25 HP (power) and 40 lb-ft (torque) from a STI and increases boost from 14.5psi to approximately 16psi.
The Stage 2 Kit continues where the Stage 1 Kit leaves off. Included with Stage 2 is the AccessPORT, as well as the complete COBB Tuning Turbo Back Exhuast. Starting off the COBB Turbo Back system is the COBB Downpipe. The CAD designed bellmouth of the COBB downpipe makes sure the airflow is smooth and efficiant. The system finishes with the modest tip of the Cat Back section that sits completely flush with the bumper. With a subtle, but deep exhaust note, the COBB exhaust achieves the highest performance while still retaining a stock like appearance.
