Push the Limits: Top 6 Aftermarket Parts for Subaru STI/WRX

Subaru STI and WRX are two of the most popular sports cars in the market today. Their popularity among car enthusiasts is due to their impressive performance, style, and affordability. However, for those who want to take their performance to the next level, there are several aftermarket parts available. In this article, we’ll discuss the top six types of aftermarket parts for Subaru STI/WRX.

1. Exhaust Systems

Upgrading your Subaru’s exhaust system is a great way to improve its performance and sound. A high-performance exhaust system can increase horsepower, torque, and acceleration. It can also give your car a deeper, more aggressive sound that will turn heads on the street.

There are several types of exhaust systems available, including cat-back, axle-back. Cat-back systems replace everything from the catalytic converter to the muffler, while axle-back systems only replace the muffler.

2. Intake Systems

An aftermarket intake system can help your Subaru breathe better, resulting in a noticeable increase in horsepower and torque. Intake systems replace the factory airbox and filter with a high-flow filter and a larger intake tube. This allows more air to enter the engine, improving combustion and increasing performance.

There are two main types of intake systems: cold air and short ram. Cold air intakes pull air from outside the engine bay, which is cooler and denser. Short ram intakes, on the other hand, pull air from within the engine bay, which is warmer and less dense. While cold air intakes generally provide better performance gains, short ram intakes are easier to install and are more affordable.

3. Turbochargers

Turbochargers are perhaps one of the most popular aftermarket parts for Subaru STI/WRX. They increase horsepower and torque by forcing more air into the engine. Turbochargers work by using exhaust gases to spin a turbine, which in turn compresses the air going into the engine.

There are several types of turbochargers available, including ball bearing, journal bearing, and twin-scroll. Ball-bearing turbos are more responsive and provide better performance gains while journal-bearing turbos are more affordable. Twin-scroll turbos, on the other hand, use two exhaust gas inlets to improve performance at low RPMs.

4. Suspension Systems

Subaru STI/WRX cars are known for their impressive handling and cornering abilities. However, installing an aftermarket suspension system can take your car’s handling to the next level. Suspension systems can improve your car’s handling and provide a more aggressive stance.

There are several types of suspension systems available, including coilovers, lowering springs, and sway bars. Coilovers are adjustable and allow you to fine-tune your car’s suspension to your driving style. Lowering springs lower your car’s center of gravity, improving handling and reducing body roll. Sway bars, on the other hand, reduce body roll during cornering, providing a more stable and predictable ride.

5. Brakes

Upgrading your car’s brakes can improve stopping distance and reduce brake fade. Aftermarket brake systems usually include larger rotors, calipers, and pads. Larger rotors provide better heat dissipation, reducing brake fade. Larger calipers provide more clamping force, improving stopping distance. High-performance brake pads provide better bite and reduce brake fade.

6. Wheels and Tires

Upgrading your car’s wheels and tires can improve its performance and style. Lighter wheels reduce unsprung weight, improving handling and acceleration. Wider tires provide more grip, improving traction and reducing stopping distance.

There are several types of wheels and tires available, including forged wheels, flow-formed wheels, and drag wheels. Forged wheels are the strongest and lightest but also the most expensive. Flow-formed wheels are lighter and more affordable but not as strong as forged wheels. Drag wheels are designed for racing and are the lightest and most affordable.


Upgrading your Subaru STI/WRX with aftermarket parts can take your car’s performance to the next level. From exhaust systems to wheels and tires, there are several types of aftermarket parts available. However, before installing any aftermarket parts, it’s important to do your research and choose parts that are compatible with your car’s make and model. By doing so, you can ensure that your car performs at its best and stays reliable.
