Exhaust Efficiency & Sound Pressure Reduction are implemented together with the R32 HKS Super Turbo Muffler. The turbo engine masters HKS were challenged to implement the following 3 characteristics together to develop the Super Turbo Muffler. Effective on stock all the way to high performance vehicles with upgraded turbines. The performance exhaust sound meets the JASMA standard. Unique exhaust sound designed specifically for the engine, so you’re promised a good sound.

• 1989 – 1994 BNR32 RB26DETT

Specifically engineered for turbo applications that require greater flow capacity than naturally aspirated applications, Turbo Exhaust systems use a straight through design. The increased flow characteristics offer an increase in boost pressure, boost response, a broader power band and increases in overall peak horsepower. Performance increases vary by application, with average gains of 10-25 horsepower.

The “Slotted Tail” on the R32 HKS Super Turbo Muffler 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.
