The Subaru WRX GD series has long been celebrated for its performance and rally heritage. One of the most effective ways to enhance its power and sound is by upgrading the exhaust system. Turbo back exhaust systems are particularly popular among enthusiasts looking to maximize performance while achieving a more aggressive sound. In this article, we will explore various performance exhaust options for the GD WRX, focusing on turbo back systems that improve both power and sound.
What is a Turbo Back Exhaust System?
A turbo back exhaust system replaces the entire exhaust system from the turbocharger to the rear of the vehicle. This includes the downpipe, mid-pipe, and cat-back sections. By replacing the factory exhaust components, a turbo back system can reduce back pressure, improve exhaust flow, and ultimately enhance engine performance. Additionally, these systems often produce a more pronounced exhaust note, appealing to many car enthusiasts.
