Toyota Supra A90/A91 Valved Sport Exhaust System

With this system you decide for yourself how loud the Supra sounds. For the A90 and A91, Valvetronic Designs built a complete exhaust system with vacuum valves, from the catalytic converter to the exhaust tips. One button switches between usable every day and fully open.

Sound and control

With the valves open the gas flows almost unrestricted and the inline six sounds raw and motorsport like. Close them and the gases go through the muffler with four chambers and the volume drops considerably, which is pleasant in the city and on a late evening start. Those four chambers keep the tone even and take the rasp away.

How it sounds
