With this pulley you will see two primary benefits: Weight Loss and Reduction of Parasitic Power Loss. The super-light weight provides a power boost, while the underdriven diameter reduces power loss. The results is a more free-flowing throttle response and more efficient power production. This is an upgrade that most drivers can actually 'feel'.

Some believe that a lightweight crank pulley has an adverse effect on the balance of the engine. This is not the case with the Subaru boxer. The Subaru engine is already well balanced and the crankshaft is relatively short, therefore the crank pulley's balancing effect is minimal. Some also believe that underdriven pulleys cause accessories and voltages to suffer. This is not true. Belt-driven accessories are regulated, becoming less efficient as rpm's increase. This results in parasitic power loss. The underdriven pulleys reduce that loss as rpm's increase.

POWER. FLEXIBILITY. CONTROL. The AccessPORT is the industry leading OEM ECU flashing, managing and monitoring assistant. Unlock power hidden within the ECU by replacing conservative factory settings with more aggressive calibrations. The result is impressive gains in torque and horsepower while maintaining a high degree of safety. The AccessPORT comes with pre-installed maps that are optimized for common performance modifications.

Tuning flexibility ranges from simply loading one of the included performance maps designed for common modifications, all the way to complete custom map authoring using the powerful AccessTUNER software (sold separately). Extract maximum power from virtually any modification while retaining the driveability and sophistication inherent in the OEM ECU.


Unlike other tuning options, the AccessPORT is truly unique in its capabilities that go far beyond typical “chipping” or “reflashing” solutions. This is where the AccessPORT clearly stands out from the competition:

Simple Installation - Just about anyone with even the most basic of automotive knowledge can quickly and easily install an AccessPORT. No computers, wire cutting/splicing or tools of any kind are required.

Base Maps - COBB Tuning provides several preloaded maps for common power modifications. Each base map is dyno developed and rigorously tested in multiple COBB Tuning facilities across the country These tests cover the spectrum of altitude, temperature, humidity, octane and fuel quality variables to ensure proper calibration and performance wherever the car is driven.

Change Maps - Since all base maps and custom tune maps are stored in the AccessPORT, you can change maps any time you want. Switch to a race gas map for that extra performance at the track. Go to the Fuel Economy map for those long boring drives. Load the Valet map to keep revs below 3,200 when you drop your car off with the parking attendant. The Anti-Theft map does not allow the car to start, keeping it safe in suspect areas or during extended parking.

Performance - Turn on your own portable performance evaluation suite! Measure 0-60mph time, 60 foot and 1/4 mile ET’s and Trap Speed. Switch to Dynamometer simulation and calculate your vehicle’s horsepower and torque.

Live Data - Monitor OEM sensor data on-the-fly. Use the AccessPORT as an additional gauge to monitor a huge number of signals, like: RPM, Coolant Temp., Battery Voltage, Intake Air Temp., Ignition Advance, Mass Air Flow, Intake and Exhaust Cam Advance and many more!

Datalogging - Onboard datalogging allows multiple channels of data to be recorded simultaneously for later review. This allows for analysis of current engine performance. Datalogs can be sent to professional tuners to provide additional power gains remotely through email!

ECU Settings - Quickly adjust ECU settings to give you more control of your car’s capabilities. Adjust idle speed and ignition timing in real time.

Trouble Codes - The AccessPORT allows you to read engine codes to troubleshoot issues and potentially save you from an expensive trip to the dealership. Once the issue is resolved, clear the codes and turn off the check engine light.

Uninstall - In the event the car must be returned to the stock configuration, the AccessPORT can be completely removed and the ECU restored to its factory condition. Perfect for trips to the dealership.

For USDM models only

Are you too busy to worry about tuning your own car? Would you like piece of mind knowing your vehicle's computer (ECU) is protected against accidental damage. Are you ready to spend less time fumbling with a laptop and more time driving?

Cobb offers you the ultimate personal tuning solution for your 2008 or 2009 STi. Save time and money with the ability to conveniently reprogram your vehicle's computer (ECU) by selecting one of the pre-installed performance "maps" that automatically optimize settings such as the air/fuel ratio, ignition timing, boost and more for performance results you can instantly feel.

However, the AccessPORT is so much MORE than just a REFLASH DEVICE. It allows you to monitor fuel economy (average and real time), perform performance tests in order to estimate your 0-60mph and 1/4 mile time, read and decipher ECU trouble codes (CELs), and monitor live data via the OEM vehicle sensors which eliminates the need for costly aftermarket gauges.

AccessPORT Features Include:

 »  Improve horsepower, torque, and fuel economy at the touch of a button

 »  Display vehicle data such as boost, RPM, temperatures and more while you drive

 »  Easy installation, no mechanical or computer skills necessary

 »  Connects to your vehicle via the OBD-II port conveniently located under your dash

 »  Exclusive ability to switch between different 'modes' on the fly

 »  Pre-calibrated to maximize performance of stock or modified vehicles

 »  Easy-to-read color display

 »  Update over the Internet to stay up-to-date with the latest features

 »  Read engine trouble codes (DTC) yourself, eliminating trips to the dealership

 »  Not a "piggyback" - once vehicle's computer has been programmed by the AccessPORT, it can be removed and the settings will stay on your computer.

 »  Not just an "ECU reflash" - AccessPORT features enhancements such as on-the-fly mode switching, data monitors, reading DTCs, performance monitors and more

 »  Can be custom tailored to your vehicle by our extensive network of professional tuners

Please Note: This package will only work with North American STi.

The flat bottom shaped muffler design results in improved high speed aerodynamic performance. The muffler inside contains continuous piping design and use of Advantex material that results in an excellent free-flow exhaust with optimized back pressure, giving greater horsepower, torque gains and a rich deep sporty sound. The use of SUS304 polished stainless steel piping, Mandrel bent to shape, state of the art CNC machine made flange, Robot TIG welding and double wall polished stainless steel or Titanium tips, provides outstanding durability and appearance.

Piping Diameter: 60mm 

Tips Diameter: 101mm

The factory WRX intercooler hoses are weak, restrictive, and prone to failure over time and under increased boost pressure. Install these upgraded hoses to prevent that failure, all while improving the looks under your hood. These hoses will hold more boost than the factory hoses allowing for prolonged life under high pressure conditions on your modified WRX. Even if your WRX is running at stock boost levels, these hoses are much smoother than the rigid, ribbed factory hoses, resulting in improved airflow and performance.

Features:
 - Silicone Construction
 - Smooth Airflow
 - Holds More Boost
 - Available in Black and Red

Includes:
 - Y-Pipe Hose
 - Throttle Body Coupler
 - Bypass Valve Hose
