HKS SUPER TURBO MUFFLER EXHAUST FOR GD SUBARU IMPREZA WRX
“High-dimensional Super Turbo Muffler debut” exhaust efficiency & sound pressure reduction are implemented together. The turbo engine master HKS challenged to implement the following 3 characteristics together to develop the Super Turbo Muffler. Effective on stock to high performance vehicles w/ upgraded turbines. The performance exhaust sound meets the JASMA standard. Unique exhaust sound designed specifically for the engine.
HKS’ Original Sound Control Technology Created the “Slotted Tail” Design
- The “Slotted Tail” was inspired by an owl’s feather. The owl’s feather-shaped exhaust tip has an advanced silencing effect. Releasing adequate air from the tail can reduce the air friction vibration which enables the sound to be reduced by approximately 2dB. HKS conducted intensive analysis of the sound level and frequency inside the vehicle’s cabin and outside the vehicle. Therefore, the best exhaust tone was tuned for both inside and outside the vehicle. Also, the low frequency was eliminated to present more comfortable sound.
