Aston Martin V8 Vantage - Race Manifolds & Catalysts
Objective
The OEM exhaust manifold & catalyst fitted to both the 4.3 and 4.7Litre V8 Vantage are horrifically gas-flow restrictive, thus performance zapping, in most part due to being 'made to a price’.
The handmade QuickSilver sports exhaust package releases the performance compromised by the OEM parts, delivering an improvement of approx. 40BHP… plus an engine that pulls with considerably more strength all the way to the redline. Complementary to other modifications that will increase Horsepower to 475 bhp and torque to 526 nm
> Please see exactly how each V8 Vantage derivative is improved by viewing the performance data below.
Design:
QuickSilver have achieved substantial performance gains by paying meticulous attention to design and manufacturing detail.
The standard 4-2-1 Components have been significantly improved by introducing:
* Tuned equal-length primary pipes of 4-1 construction
* A sequential collector cone which enables uncompromised exhaust gas scavenging
* 2mm gauge 316 grade stainless steel pipework
* Laser cut flanges
* All joints and bends fully purge welded (inert gas is used to protect the weld seam until it has cooled to the point that oxidation does not occur, thus prevents cracking, corrosion and deformation)
* 200 cell density Race-catalysts
and to round-off
> A choice of Quicksilver Sports silencers to make the whole package sing as only an Aston should / can.
Testing:
The complete exhaust system has been arduously durability-tested, by the 'Boffins' around the world famous Millbrook proving ground circuit under a thermal cycle which would accelerate the onset of any potential error state modes or material failure. The durability concept has been further proven under road mileage accumulation tests for driveability where city driving, motorway cruising or spirited country lane driving have all been tested to make certain no error state driveability modes are present.
Result:
Not only does the system enable flywheel performance, it reduces weight by 18kilos too.
The system is manufactured by QuickSilver
The system can be added to other aftermarket parts (eg if car already has sports cats and silencer, the manifolds can be added independently).
Demonstration:
The development car, ‘Jessica’ (shown on the attached video) is being introduced this Sunday August 14th at Lord Pembroke’s ‘SuperCars at Wilton Park’ event.
It will be on the lawn where it can be seen and heard > The development technicians will be on hand to demonstrate & answer questions.
It will also be competing in the ‘Rev Off’ competition where it faces stiff competition from the boys from McLaren with their new MP4, and all the ‘never-seen-one’ Supercars.

Hi Paul
I have received delivery of the QuickSilver sports exhaust for my BMW X5 3.0D and it sure looks great.

Dear Barry
I have replaced the stock headers with Evo headers and now the QuickSilver exhaust sound is amazing.
