HKS Super Turbo Muffler Cat-Back Exhaust System - Subaru WRX STI EJ20 (2014+)
The HKS Super Turbo Muffler Cat-Back Exhaust System is designed for the Subaru WRX STI (2014+) equipped with the turbocharged EJ20 boxer engine, delivering an ideal combination of high exhaust flow, enhanced performance, and refined acoustics. Engineered to maximize engine efficiency while maintaining the comfort required for everyday driving, it is an excellent upgrade for both stock and performance-oriented vehicles.
The optimized design reduces back pressure and improves exhaust flow, allowing the engine to breathe more efficiently. This results in quicker throttle response, more efficient exhaust scavenging, and a broader, more usable powerband. The system is equally well suited for stock engines and vehicles equipped with performance upgrades.
The exhaust note has been carefully engineered to give the turbocharged Subaru boxer engine a deep, sporty, and well-balanced tone without excessive noise or unwanted cabin resonance. The result is an engaging sound under acceleration while maintaining excellent comfort during daily driving and long-distance cruising.
Manufactured from high-quality stainless steel, the exhaust system offers outstanding corrosion resistance, excellent heat resistance, and long-lasting durability. HKS's precision engineering ensures exceptional fitment, making the system a direct bolt-on replacement for the factory exhaust.
The center pipe is designed for optimal exhaust flow, and all ground clearance specifications are based on vehicles equipped with the factory suspension. Ground clearance may vary depending on the vehicle's suspension setup and ride height.
