[Product Appeal / Recommended Points]
● Low-backpressure design that maximizes turbo engine performance
The HKS Super Turbo Muffler adopts a φ75 straight-through structure with no constriction. By significantly reducing exhaust resistance, it unlocks the true potential of turbo engines, improving response and delivering stronger pull at higher RPMs.
● Balances sporty performance and quietness
It overturns the conventional idea that “the faster it is, the louder it gets,” while maintaining a comfortable level of quietness inside the cabin. The moment you step on the accelerator, you can enjoy a dry, powerful sports-car-like exhaust note. It is suitable for everything from everyday driving to spirited runs.
● High-quality S304 stainless steel construction
The main material is S304 stainless steel, offering excellent durability and corrosion resistance. It is easy to maintain a beautiful appearance over a long period and delivers high reliability even in harsh environments.
● Powerful left-right 124 mm tail ends
Featuring large-diameter 124 mm dual tail ends, it greatly enhances the rear-view presence. It creates a sporty yet premium styling and further highlights the appeal of the Impreza WRX STI.
● Full kit specification with included center pipe
A center pipe is included, contributing to improved performance throughout the entire exhaust system. You can feel changes in exhaust efficiency and driving response that cannot be achieved by replacing only the rear section.
● Certified model that complies with vehicle inspection requirements
This is a reliable, inspection-compliant model with certification number “JQR40124179.” It is designed for public-road use while still allowing you to enjoy the performance and sound that only a sports muffler can provide.
● Excellent fitment through dedicated design
Developed specifically for the GVF Impreza WRX STI, it achieves high-precision fitment. Its strong compatibility with the factory layout also makes for a natural installation feel.
