installed (without snow chains) is 210 km/h (131 mile/h) for
H rated tyres or 240 km/h (149 mile/h) for V rated tyres.
When using snow chains, note that:
• Snow chains must only be installed to the rear wheels
• Only Aston Martin snow chains should be used
• Snow chains must not be used on roads which are clear of snow
• The maximum speed with winter tyres and snow chains fitted is 48 km/h (30 mile/h)

Exhaust (09.00)
Silencer Assembly (09.01)
Variable Flow Silencer Assembly
The rear silencer assembly has a variable fl ow path controlled by two bypass valves.
The system is intended to enhance top end performance in mo tor sport applications and will not operate in most normal
driving conditions.
By directing exhaust gasses through a modified path at high vehicle speeds, exhaust back pressure is reduced and top end
performance is enhanced.
As engine speed increase from idle, the bypass valve is open until the engine speed is 1500 rpm.
From 1500 rpm to 3000 rpm, the valve is closed
Above 3000 rpm the bypass valves state is load dependent (fully open at higher loads).
