The Aston Martin DB9 had 510 bhp (380 kW; 517 PS) and 620 N⋅m (457 lb⋅ft) of torque from the engine and came with carbon ceramic brakes as standard. It has a top speed of 183 mph (295 km/h) and a 0 to 60 mph (97 km/h) time of 4.5 seconds.

At GCAP we have designed a package to further refine the British sports car's character with a few simple modifications.


We use a Capristo exhaust system on our tuning packages for this vehicle.

This is the Capristo sports exhaust system for the Aston Martin DB9 and the DBS V12. Made of 1.4828 (T309) polished stainless steel. The system can be controled via the on-board control system. Optionally you can order our programmable control unit.

Options include:

  • Muffler

  • Cat replacement pipes silenced

  • Cat replacement pipes not silenced

  • Set sports cats 100cpi

  • Programmable valve controller CES-3


We have developed our own software to increase the cars performance. This comes in two forms. A stage 1 map (I.E. a software only calibration with no hardware changes) and a stage 2 (with our Capristo exhaust system).

When tuning we measure afr, ignition timing, intake temps, EGTs etc. to ensure our tune is as safe and reliable as possible whilst drawing the most out of your supercar.


We have seen gains up to 530bhp.


As with most Aston Martin, the brake system is excellent. However we can offer modified braided brakes lines. Our lines have a stronger wall density delivering a more precise and accurate brake pedal feel. This translates into more confidence in your supercar.
