Flywheel Power Output:

GRD Race Exhaust System - Weighing in at just 16KG`s this exhaust is possibly the lightest on the market - a massive 40% lighter than the standard system. Using fully slip jointed stainless steel construction this exhaust gives exceptionally good flow as it utilises a very straight and smooth exhaust path.

Specification is as our Drag Exhaust System but instead re-vents exhaust gas from the screamer pipe back into the mainpipe reducing noise levels to help comply with both track and road regulations.

VF34 Turbo - The IHI VF34 is a roller bearing turbo as used found on the STI JDM models and the prefered choice for group N rallying due its fast spoolup characteristics.

De-Cat Up Pipe - Unlike the WRX, this Up Pipe has no restrictive Cat increasing flow and compliments our 2.5" Stainless De-Cat System.

Hyperflow Top Mount Intercooler - At nearly 2.5 times the volume of the standard intercooler, the Hyperflow Top Mount Intercooler is absolutely the largest top mount intercooler that is practical to install in the late model STI vehicles.The larger surface area generates a lower intake air temperature allowing greater ignition advance and more power.

Free Flow Air Box Panel Filter - High performance replacement for the original panel air filter. Constructed from a cotton weave which increases air flow by upto 40%.

Syntek Motorsport Fuel Pump - A crucial part to any engine modifications, is the ability to reliably supply your engine with enough fuel. This pump directly replaces the standard unit and has the ability to supply 2.25 litres per minute @ 5 bar pressure. The standard pump generates 1.1 litres per minute @ 5 bar.

STI Fuel Injectors - They are 550cc and will improve your fuel delivery for high safe horsepower when used in conjunction with one of our Fuel Pumps.

EcuTek ECU - we use EcuTek software to reprogram your ECU via the diagnostic port of the car. We retain all the car's clever electronics but re-map ignition curves, fuel maps and the closed loop boost control system. The ECU remains programmable so if in the future something needs to be changed then we can. The only way to tell that that either conversion has been performed is to drive the car. There are no visual clues. Even the Subaru diagnostic tool does not show that the ECU has undergone brain surgery.

Rolling Road Tested - Our Dyno Dynamics chassis dynamometer measures engine power via the driving wheels in an accurate and repeatable method. Your vehicle's dyno runs are recorded in real time, and printed out in full color for your records.


Optional Extras

Please call us on 07973 787812 or E-mail to discuss any optional extras and prices.

Exhaust Downpipe Heat Wrapped Or Ceramic Coated - This serves 2 purposes. To reduce heat soak into the engine bay and to keep the internal pipe wall temperatures up to aid the removal of waste gases through the exhaust system.
Heat Wrap 50.00 inc. VAT Fitted

Turbosmart Blow Off Valve - Features the unique variable exhaust port system resulting in superior venting of excess pressure, a popular choice for the street. Fully adjustable via Turbosmart's unique Quick Wrist action (no tools required). Supplied with full fitting kit (where required). Easy DIY fitment.

STI Bonnet Scoop - The larger STI Bonnet Scoop allows a greater volume of air necessary to fully benefit the STI Intercooler's greater surface area.

GRD Cold Air Intake - By eliminating the standard airbox resonator and snorkel we are able to source cold air directly from custom vents in the front foglight cover. This helps to dramatically increase airflow to the standard airbox, lowering inlet temperates and in turn give a significant increase in both power and torque.

This package does require STI foglight covers, however we can offer these as an option on most WRX models.

GRD Drag Exhaust System - Weighing in at under 16KG`s this exhaust is possibly the lightest on the market - a massive 40% lighter than the standard system. Using fully slip jointed stainless steel construction this exhaust gives exceptionally good flow as it utilises a very straight and smooth exhaust path.

With a unique Screamer Pipe design this exhaust system vents exhaust gases seperately from the exhaust turbine and turbo waste gate through a main 3" pipe and a second 1.5" pipe. Other exhausts on the market use an open neck design causing the paths of the exhaust gases collide once the turbos wastgate is opened, causing exhaust gas turbulance and reducing the speed at which gas can flow creating backpressure. This in turn slows down the turbo reducing the speed at which and its ability to flow air and causes exhaust gas to stay in the combustion chamber longer creating unwanted heat buildup, lowering the point of ignition advance before detonation will occur. This exhaust will give the advantage over a regular open neck downpipe of the ability to increase ignition advance, increase the speed at which the turbo can spool up and the amount of air which it can flow. All leading to a significant increase in both power and torque.

GRD Sport Exhaust System - Weighing in at just 16KG`s this exhaust is possibly the lightest on the market - a massive 40% lighter than the standard system. Using fully slip jointed stainless steel construction this exhaust gives exceptionally good flow as it utilises a very straight and smooth exhaust path.

Fully Road Legal and MOT friendly this exhaust has all the same features as the GRD Race Exhaust System but uses a 300 CELL Sports Catalitic Convertor to help it to conform with current MOT exhaust emmisions requirements. This will however reduce exhaust gas flow, slightly reducing potential power output especially on high power applications.
