Products description
DTH builds the first legal valved exhaust system for the JDM classics GT86 and GT86 Facelift
Specifications:
- Pipe Diameter: 63.5mm
- Dual valve control to comply with legal limits
- ECE-approved – no registration required!
- Noise levels:
- Valves closed: 78dB / 80dB
- Facelift model, valves open: 106dB
- Pre-facelift model, valves open: Info to follow!
Valve Control & Modes:
The valve control is switchable via Track Mode. When Track Mode is activated, the valves close only within the legally required speed/RPM range for maximum legal sound.
In Normal Mode, the valves remain closed in all gears up to 30% throttle load and 5000 RPM for optimal long-distance comfort.
Modular Exhaust System:
The system is fully adjustable on the vehicle. The rear muffler, outlet bends, and tailpipes can be precisely aligned and set.
Valve Operation Chart:
| Vehicle Condition | Gear | Speed | Mode | RPM | Valve State |
|---|---|---|---|---|---|
| Idle | P | 0-5 km/h | Normal / Track | - | Closed |
| 2nd | - | Track | - | Open | |
| Driving | 3rd & 4th | 20-80 km/h | Normal / Track | 0-5000 | Closed |
| 3rd-6th | 80-226 km/h | Normal | 0-5000 + load > 30% | Open | |
| 3rd-6th | 80-226 km/h | Track | 0-7000 | Open |
Control System Update:
The system now recognizes Track Mode when pressing the ESP button twice, enabling Track Mode sound while keeping ESP/ABS activated.
Registration & Installation:
- The exhaust system has an ECE approval, meaning no additional registration is required. However, we still offer registration at our facility if needed.
- The vacuum system for valve control and the CAN bus-based control unit are included in the package.
- A detailed installation guide is available to help you install the system yourself – we are happy to provide it upon request.
