STi Performance Stage3 Kit 'With Cats'
(Approximately 400 H.P Plus) Please note, all power outputs stated are only approximations, for reference purposes and will vary depending on each vehicle, its condition, fuel and modifications.

Kit Contains:

1. AccessPort ECU Upgrade: The 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.
2. Short Ram Intake: Using the same design feature of the velocity stack found on the inlet to the MAF sensor in the factory box this cast aluminum intake carries the velocity stack radius outward to mate up with a 4.5" high flow cone filter.
3. Custom 4 into 1 Stainless Steel Header and Uppipe Combo: Designed to significantly gain horsepower and torque.
4. Blow Off Valve:
5. Xcceleration 3" Turbo-Back Exhaust System with Two Cats: Our Turbo-back Exhaust System features the newest technology in Super Hi-Flow Catalytic Converters and Exhaust Piping. Air flow is increased dramatically to greatly increase your HP and Torque. Our System is a constant 3" pipe size, which retains low end torque and produces high air flow capacity. Our Super High Flow cats flow over 502 cfm, increasing exhaust flow which reduces backpressure. Backpressure forces exhaust gases back into the combustion chamber and contaminates the next burn cycle. Reduced backpressure increases exhaust scavenging from the combustion chamber giving you a cleaner, more efficient burn. The increased momentum of the exhaust pulls more air/fuel into the cylinders, hence increasing low end torque.
6. Large Top Mount Intercooler: Dual intercooler inlets take full advantage of the intercooler's size by evenly distributing the air across the bar- and-plate core for more efficient cooling, while the large cast alloy end tanks distribute heat evenly across the intercooler and aid in smoothing air flow. Massive bar and plate construction reduces pressure drop over stock allowing the turbocharger to spin slower while producing the same boost pressure in the intake manifold. Not only will this prolong turbocharger life but will also reduce the air temperature exiting the turbocharger, effectively increasing intake charge density.

NOTE: 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.
