Quicksilver Race Manifolds & Catalysts Aston Martin V8 Vantage 05-12

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 it was the sensation that was lacking. 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 2011 GT4 Challenge, 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 the compromised OEM parts, delivering an improvement of approx. 40BHP, 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.

Features:

• Longer, equal-length primary pipes of 4>1 construction increases and concentrates power delivery.
• Bespoke sequential collector cone which enables uncompromised exhaust gas scavenging.
• 2mm 316 grade stainless steel primary tubing
• Laser cut flanges
• 200 cpsi metallic race catalysts
• All joints and bends fully purge-welded to prevent cracking, corrosion and deformation.

The complete QuickSilver package has been arduously tested around the world famous Millbrook proving ground under a thermal cycle that would accelerate the onset of any potential durability issues. The durability has been further proven under road mileage accumulation tests, in a variety of conditions, to ensure that durability matches the original parts.

And, toughest of all, successfully tested on the race track during the Britcar 24 Hours at Silverstone in October 2011 on the Vantage Racing GT4. These Manifolds & Catalysts deliver a very different sound, the same as the GT4. A crisper, sharper crackle that cuts and re-forms up and down through the gears. Not only does this package enable flywheel performance, it also reduces weight by 40lbs.
