The Subaru WRX is a beloved vehicle among car enthusiasts, particularly for those looking to enhance performance and power. When it comes to turbocharged builds aiming for 300+ horsepower, selecting the right turbo back exhaust system is crucial. Two popular brands in the aftermarket scene are Cobb Tuning and Perrin, both offering high-quality options that can help you achieve your performance goals.
Understanding Turbo Back Exhaust Systems
A turbo back exhaust system replaces the entire exhaust path from the turbocharger to the rear of the vehicle. This upgrade is essential for maximizing airflow, reducing back pressure, and ultimately increasing horsepower. With a proper turbo back exhaust, WRX owners can expect improved throttle response, better turbo spool, and a more aggressive sound.
