Description
The HKS Hi-Power Dual Muffler is a cat-back exhaust system developed specifically for the Toyota GR Supra (A90/DB42, B58 engine). HKS used a straight-through silencer structure to emphasise the distinctive tone of the six-cylinder while reducing exhaust restriction. The result is a measured increase in sound level over stock with dual 119mm titanium tips.
Features
- Material: SUS304 stainless steel
- Tips: dual titanium, 119mm each
- Centre pipe diameter: 85mm (largest section, excluding silencer and tips)
- Main pipe diameter: dual 70mm
- Noise level: approx. 90 dB close / 66 dB idle in sport mode (stock: 88 dB close / 58 dB idle)
- Straight-through silencer structure
Fitment
- Toyota GR Supra, chassis DB42, engine B58, 2019 onwards
Notes
- Centre pipe diameter refers to the largest section of pipe, excluding silencer and tips. Measured on stock suspension.
- Road clearance is measured at the lowest point of the HKS muffler on stock suspension - verify clearance if the vehicle is lowered.
- Bracket and stay designs may change without prior notice.
- JDM product: any HKS certification applies to the Japanese market. Check your state's regulations before road use in Australia.
