7 Modifications You Can Do for Your Subaru WRX STI

The Subaru WRX STI has made quite a name for itself among rally-goers and automotive aficionados. It's gained a reputation for delivering top-notch performance, which has made it a favorite among Subaru fans and car lovers alike.

That said, the Subaru WRX STI can be taken to the next level of performance with various alterations. From exterior to interior and front to back, there are a lot of different upgrades that can be done to the car. It can be hard to determine which customization is best for you, so we have compiled a list of the top modifications for the WRX STI to get you going:

1. Performance Exhaust

A performance exhaust is one of the most important modifications for a Subaru WRX STI. It will help increase the power and efficiency of the engine and improve exhaust flow, resulting in more horsepower and torque.

2. Cold Air Intake

A cold air intake is another important modification that can help increase the power output of your vehicle. It will help draw in cooler air, resulting in a more efficient combustion process, which leads to better performance.

3. BPV/BOV

At high boost levels, the stock valve may not be able to contain the pressure, causing a leak. This can reduce the power of your Subaru WRX STI and restrict airflow. Installing a Blow Off Valve (BOV) or Bypass Valve (BPV) can help to prevent this, as it vents off any excess pressure that the stock valve can't handle.

4. Suspension

The suspension on the Subaru WRX STI is already quite good, but if you're looking to get the most out of your car, then it's worth upgrading to an aftermarket suspension system. This will help improve the handling of your vehicle, making it more responsive and giving you better control.

5. Brakes

The brakes on the Subaru WRX STI are good, but if you're looking to get the most out of your car, it's worth upgrading to an aftermarket set. This will help improve the stopping power of your vehicle and make it more responsive when you need to come to a quick stop.

6. Wheels and Tires

A set of aftermarket wheels and tires can help improve the look and performance of your vehicle. A set of lightweight wheels will help reduce the unsprung weight, which can help improve handling and acceleration. A set of performance tires will also help improve grip and traction, resulting in better performance.

7. ECU Tuning

ECU tuning is the process of reprogramming the engine control unit to optimize the performance of the engine. This can help increase the power and efficiency of the engine, resulting in better performance and fuel economy.

Conclusion

There are a variety of aftermarket modifications that can help improve the performance of your vehicle. From cold air intakes and exhaust systems to wheels and tires and ECU tuning, these modifications can help increase the power and efficiency of your vehicle. It's important to research each modification and determine which one is best for your vehicle and driving needs.
