The Aston Martin V8 Vantage was originally introduced with 380 bhp (a substantial number) and 170 mph (a significant speed) but some owners reported that the cars didn't feel fast enough.
However, these cars are fast machines and the Aston Martin V8 always had the sex-appeal to beat the Porsche 911! - It was the sensation that was lacking and since 2006 QuickSilver have offered a range of alternative silencers that provide a proper V8 soundtrack to satisfy most enthusiast drivers.
As a partner of Aston Martin Racing in the GT4 Challenge Great Britain, QuickSilver have been able to draw on their experience to design and develop a set of Manifolds and Race-Catalysts for road-going AM V8s that offer a serious improvement on the original components.
The OEM exhaust manifolds fitted to both the 4.3 and 4.7 V8 Vantage are horribly restrictive at medium and higher rpm, due to being made-to-a-price and the inevitable resistance imposed further upstream by the OEM catalysts.
The handmade QuickSilver exhaust package recovers the performance lost by by the compromised OEM parts, delivering an improvement of approx. 40BHP (see the performance data below), and an engine which pulls with more strength all the way to the redline.
QuickSilver have achieved this performance gain by paying meticulous attention to design and manufacturing detail.
