The Subaru WRX has long been a favorite among car enthusiasts, particularly for its impressive performance and tuning potential. One of the most effective upgrades for increasing horsepower is the turbo back exhaust system. This article delves into the benefits of upgrading to a name brand 3.5-inch turbo back exhaust system, which can help elevate your WRX’s power output to over 310 horsepower.
Understanding Turbo Back Exhaust Systems
A turbo back exhaust system replaces the entire exhaust pathway from the turbocharger to the back of the vehicle. This includes the downpipe, mid-pipe, and axle-back sections. Upgrading to a high-performance turbo back exhaust can significantly improve exhaust flow, reduce back pressure, and enhance turbo spool time, ultimately leading to increased horsepower and torque.
Benefits of Upgrading to a 3.5-inch Exhaust System
- Improved Exhaust Flow: A larger diameter exhaust allows for better airflow, which is crucial for turbocharged engines.
- Increased Horsepower: Upgrading to a 3.5-inch system can help achieve power outputs of 310+ hp.
- Enhanced Sound: A performance exhaust system provides a more aggressive and sporty sound, enhancing the driving experience.
- Weight Reduction: Many aftermarket exhaust systems are lighter than stock, contributing to overall vehicle performance.
Choosing the Right Name Brand System
When selecting a turbo back exhaust system, it’s essential to choose a reputable name brand known for quality and performance. Some popular brands include:
