Case Studies

Availability to coincide with the car’s launch

Working with the UK’s leading Jaguar tuning specialist, Paramount Performance, QuickSilver have designed and developed a cat-back ‘Sports’ exhaust system for the 2007 model Jaguar XK8.

The brief was to have this system on the market for the Cars’s launch in Summer 2006.

All modern vehicles have to meet the same worldwide regulations on sound and emissions. The car manufacturers are inventing ever more ingenious ways of distinguishing their model’s acoustics. Like the use of exhaust valves to alter the sound at different throttle position & engine rpm (BMW & Ferrari), different length tubes within the silencer to generate organ-like chords at varying pressures (Ferrari) and harnessing panels within the car’s structure to resonate a subtle depth within the cabin (Jaguar) – are all just some of their clever tricks, but for many enthusiast drivers the muffled exhaust note is still unsatisfying.

The QuickSilver team were able to devise a new look together with an appropriate Sports sound to give the car a distinctive note rising in pitch with rpm. A superb sound is created by the removal of restrictive silencer boxes and the performance is enhanced by their replacement with more efficient silencing to release an extra 18 bhp

QuickSilver have developed a ‘Sports’ exhaust that is lightweight, robust, and free flowing. Manufactured from aircraft-grade type-304 stainless steel and Tig welded throughout. All pipe work is mandrel bent to maximise the flow of gas and it is finished off with distinguished ‘Aston’ polished tips that match the curvature of the rear apron.
