I don't know if these people do pipe work for Audi, but they have done some fairly specialist work for my other car (V12 XJS) that was excelent.
bespoke made SS twin pipe with baffles raken out and fully compensated for uprated air boxes and Timing.
They system with airbox mods gave me 20% more midrange power ona dyno for £520 + VAT and fitting.
