Accessport is a mult-featured ECU reprogramming device for your Subaru
WRX or STi. The Accessport comes loaded with multiple maps for various
setups (i.e. stock, turboback exhaust, etc.). It also allows for custom
tuning through Tuners or self-tuning by downloading Cobb's Racer Tuner
program. Your Subaru can easily be returned to stock at any time, as
the Accessport retains your stock base map. In addition, the Accesport
functions as a scan tool, diagnosing and clearing check engine lights
(CELs) and other vehicle parameters. The Accessport's color display
allows the user to display a variety of parameters including
dynamometer testing and real time data.

All power outputs stated are only
approximations, for reference purposes only and will vary depending on
each vehicle, its condition, fuel, modifications and tuning. All engine
modification components, except those that are exempt, have been
designed and are intended for off-highway application. These components
are for racing vehicles only, which may never be used on public roads
and highways. Federal and many state laws prohibit the removal,
modification, or rendering inoperable of any device or element of
design affecting vehicle emission or safety in a vehicle used on public
highways. Violation of such laws may subject the owner or user to a
fine or penalty. Installation of this part may void the warranty
coverage, if any, on your vehicle. Vehicles modified by the use of
performance parts may no longer be lawfully used on public highways.

kit is designed to better your cars performance and feel. The cutout
works by welding into your stock or modified exhaust. They can be
placed anywhere after the headers. To open the cutout you press a
switch, which opens cutout, releasing your exhaust. This enables you to
bypass your muffler, increasing horsepower and giving your car an
extremely throaty rumble.
Under Federal EPA regulation, replacement of original catalytic
converters is allowed only if the original converter(s) is missing, or
the vehicle has more than 50,000 miles or is at least five years old
and the need for a replacement has been established and documented, or
a local inspection program has determined the existing converter is in
need of replacement. Please note that no aftermarket catalytic
converters are legal for installation in California on OBD II vehicles
(some 1994 & 1995, and all 1996 and later vehicles). There
is a chance of seeing a CE Light: Inefficient cat code when running
less than two cats, so if seen, contact us for the mechanical fix (sold
separately). All performance parts have been designed and are intended
for off highway application only. Installation of these parts on a
vehicle intended for use on public roads may violate state or federal
laws and regulations including those relating to emissions requirements
and motor vehicle safety standards.
Please replace the following OEM gaskets when
installing the kit: header, uppipe and turbo gaskets. Xcceleration.com
highly recommends you install a boost gauge, exhaust gas temperature
(EGT) gauge, and air/fuel
gauge to monitor your car and ensure safe, reliable performance. Gauges are sold separately
