The Quicksilver ‘Race' Catalysts have a microscopically thin Fecralloy metallic core of 200 cpsi to which the essential Platinum and Rhodium are applied at a much greater density (25 grams per cubic foot compared to 10 grams on a typical aftermarket product).  This all results in a flow area of approximately 85% whilst remaining clean enough to meet emissions requirements. 

- Dyno tests show a 16bhp improvement, increased mid-range torque and noticeably improved throttle response.

- Accelerated gas-flow draws heat away more efficiently to reduce under-bonnet temperatures – particularly important for a tuned engine.

- These 'Race' catalysts produce a crisper exhaust note which, coupled with the improved response, deliver some of the 'GT4' experience.

- Substantial weight reduction of 6 kilos over the OE parts.

- The original lambda sensors are retained in their correct positions for the proper operation of the OBD2 (on-board diagnostics) system.

- In certain applications an ECU re-tune may be required to avoid a CEL.

- They are 'plug & play' requiring no retuning or other modifications. 

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.

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.Not only does this package enable flywheel performance, it also reduces weight by 18kilos.These are manufactured by Quicksilver in the UK and available through QuickSilver Dealers.

 - The significant improvements over the OEM 4>2>1 parts are:

- Longer, equal-length primary pipes of 4>1 construction = increases and concentrates power delivery.

- Bespoke sequential collector cone = enables uncompromised exhaust gas scavenging. 

- 2mm 316 grade stainless steel primary pipework = durability.

- Laser-cut flanges = consistency 

- 200 cpsi metallic Race-catalysts = reduction in resistance. 

- All joints and bends fully purge-welded (inert gas is used to protect the weld seam) = prevents cracking, corrosion and deformation.

QuickSilver have engineered an improved exhaust system for the 2024 Aston Martin V8 Vantage. Our system is classed as a Titan Sport system which uses a mix of premium metals for their unique performance and sound qualities.

Titanium is used as the silencer casing, being stronger it is used in a thinner gauge. When it resinates it produces higher pitched notes. Type 304 Stainless Steel adds a littler more depth throughout the rev range and is used for all the mandrel bent pipe work.  

In addition we integrate our Sound Architect™ active valves so the driver can open and shut the valves at his or her discretion. The factory exhaust from Aston Martin does not have any valves and thus does not allow the driver to choose. 

Our system retains all the in-car functionality including the exhaust 'exaggeration' button. This button uses artificial sound through the speaker set up and is default from the factory.

Couple with our OPF/GPF delete pipes for the ultimate sound upgrade.

• Vastly improved sound over factory exhaust, more depth throughout.

• Valves offer two defined sounds at a touch of a button, suited to every environment.

• Titan Sport uses Titanium and Type 304 Stainless Steel.

• Retains all in car functionality inc. exhaust 'exaggeration' button.

• Works in relation to throttle position, can remain relatively civilised when required.

• Less weight and better flow equals improved performance.

A lighter weight component that has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing that sports car sound.

These OPF/GPF delete pipes unrestrict these 2024 on Vantages and unleash their full potential. A much crisper sound is achieved with more volume throughout as the flow of exiting gases is greatly improved upon.

Retains the correct bungs for the sensors. 

Couple with our rear valved section for the ultimate sound upgrade.

• A much crisper sound with more volume.

• Made from T304 Stainless Steel.

• Improved throttle response.

• Lighter benefiting all areas of performance.

• Retains the correct bungs for the sensors
