Overview
The FactionFab Axle Back Exhaust with Onyx Black Tip is a direct-fit performance upgrade designed specifically for the 2008-2014 Subaru WRX STI Hatchback and 2011-2014 WRX Hatchback models. This axle-back system replaces the factory rear exhaust section to enhance exhaust flow, reduce weight, and deliver a deeper, more aggressive exhaust note that complements Subaru’s turbocharged engines. It’s ideal for enthusiasts looking to improve sound and performance without the complexity of a full cat-back system.
FactionFab is known for precision engineering and high-quality craftsmanship, focusing on Subaru platforms with a performance-first mindset. This axle-back exhaust is constructed with durable stainless steel and finished with a sleek Onyx black tip, combining both style and function. The design balances sound volume and tone to avoid drone while providing a satisfying growl under acceleration, making it a refined yet aggressive upgrade for street and spirited driving.
For Subaru owners, this axle-back exhaust offers tangible benefits including improved throttle response and a more engaging driving experience.
