|HKS Hi-Power Exhaust Silent Hi-Power Exhaust |
Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.
For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Certain applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler. Like Drager Exhaust systems, Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies.

Cold Air or Short Ram Intakes for 2.5 NAs 1998-2007
The AEM Performance Air Intake Systems have been engineered to be an affordable and easy way to boost the horsepower and torque of your engine. The restrictive factory air filter and air intake housing are replaced with this AEM air intake system which was designed, tuned and dyno-tested to fit specific Subaru Impreza models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The sound your engine makes when accelerating is also modified to a fuller, more aggressive resonance allowing you to hear and feel the horsepower upgrade. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the engine breather hose. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Intake for 2.5 NAs 1998-2007
The Secret Weapon Intake was designed, to increase air intake volume to the engine. The concept is to create two different air velocity profiles, one traveling at higher speeds than the other. This technology increases air volume and speed to the engine, which naturally feeds the engine 3x more air than the conventional air intake system. The intake pipe is bent out of high quality 6061 Aluminum on our Automated CNC mandrel bender. Polished to a high show quality finish. The SW1 Air filter features a tuned velocity stack to increase velocity and decrease turbulence. Only Comes In Polished.

AP Subaru 2.5L, Crank Pulley
The AP lightweight crank pulley for your Subaru EJ20, EJ22, and EJ25 motor is going to add about 7chp, lost from the OEM heavy pulley. The CNC machined aluminum pulley is made from high grade 6061 material and finished in either a Flat Black or Gloss Silver color. The pulley has been broached for a perfect fit and the redesigned lightweight center gives you the best possible advantage over the competition.
The AP pulley is the same diameter as the stock pulley. Keeping the diameter the same allows no issues to occur with the alternator as under driven pulleys do sometimes. Weighing only 1.0lbs, it is almost 5lbs lighter then stock. This is also the lightest crank pulley on the market. This gives you quicker throttle response as well as more horsepower and torque. Saving on rotating mass results in better performance.
The AP pulley is a great performance part for your Impreza, WRX, STI, Legacy, and Forester vehicle.

The SMT PIGGY-BACK ECU has been designed to answer the question
“how is my car going to get tuned”?
The SMT8 piggy-back system has unparalleled performance and a quantum leap of technical innovation. This is all possible with the latest 16 bit DSP processors, crammed full of features that you've never seen before. T
One of the new features is the fully programmable engine protection, which monitors the engine's performance. Should anything exceed the engine's specifications, the SMT8 will gradually reduce the engine's power after a programmable time delay, in essence looking after your engine. This is absolute MAGIC!
The external display output is also new for the SMT8 series. It allows our digital display to receive data from the SMT8 and selectively display the desired value without the presence of a PC. The displays are small with bright attractive LED colour options. Multiple values can be displayed on a single display by simply toggling between them.
An average installation consists of connecting 6 wires to the vehicle's ECU wiring loom, changing the settings of the SMT8 in the setup section of the LetRipp II Tuning Software and voila - you are ready to re-tune the vehicle. An experienced installer can install an SMT8 unit within 30 minutes for a basic installation. The primary features of the SMT8 will take longer to install, simply because there are more wires, but it is worth the wait.
The SMT8 can drive one extra injector (13 ohm) for supplementing fuel at high boost. The extra injector can be controlled via Throttle/RPM, AMP and Engine Temp maps. This allows for precise fuel delivery at boost conditions - a feature which is very popular with turbo and supercharger installations.
Set-points is a feature which makes the SMT8 stand apart from the other piggy back chips. It allows for the implementation of gear shift lights, fan control, idle assistance to mention a few. It has three relay outputs which can be switched on via 14 different signal sources. All Set-point functions can be combined in a logical fashion, and full polarity (higher than/lower than) selection is possible, even switching between the two operating maps is possible.
Two full operating maps (Map A and Map B) are present in the SMT8. Each operational map is capable of being switched into operation in real time while you drive or even when your Set-point function comes true. Switching between the two maps can also be achieved by having an external dash board switch installed, having one operational map for max power and the other for fuel consumption. The options are endless! The LetRipp II Tuning software is able to switch and lock operational maps to facilitate the tuning process.
Two wide band LSU-4 channels can be tuned simultaneously with the SMT8 version 3. This is feature is the major difference between version2. A large 16 x 24 map (384 tune sites) allows for the precise AFR (Lambda) signal modification via the two wide band inputs and outputs. The AFR is mapped via Throttle/RPM, AMP and Engine temperature. Two narrow band AFR (Lambda) probes can also be tuned simultaneously with the two wide band probes. This feature is invaluable for V6 and V8 applications where there are two wide bands probes and two narrow band probes. All 4 lambda probes can be tuned at the same time with one SMT8 unit.
Detailed HELP is available on the unit while the software screen is open. Simply move your mouse over an item and right click and hold down the button. A help description will appear detailing the function of that item. This help feature is invaluable because you get the help from the unit and not from an out of date printed manual. The software manual is also provided with every purchase and should be used as a reference guide, where the item help should be treated as the Holy Grail.
The mapping of all this is done via a high speed USB port and the user friendly, state-of-the-art LetRipp II Tuning Software. All tuning is done in real time and all entered values have immediate effect on the operation of the unit. All in all the SMT8 is the best piggy-back system on the market. It can do everything ... except make a cup of coffee!
