DTH builds the first legal valved exhaust system for the JDM classics GT86, and to cover the special editions, we have also adapted it to the spoiler design of the TRD models with a 4-pipe look.
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.
The system is fully adjustable on the vehicle. The rear muffler, outlet bends, and tailpipes can be precisely aligned and set.
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 |
The system now recognizes Track Mode when pressing the ESP button twice, enabling Track Mode sound while keeping ESP/ABS activated.
The pipes shown in the pictures are 4 x 90mm with a rolled edge. Other sizes are available upon request.
