Was considering a Milltek for the S4, now having second thoughts after the recent problems!! Thought I would share this with you guys anyway Received a quote from one of Millteks resellers for a S4 B6 cat back system resonated. Price including vat & delivery £660 all in!! Thought this a very good price ! There is one slight problem, response from Milltek about availability, forwarded to me from reseller; "Many thanks for your enquiry, please be advised of the following stock situation; Audi S4 4.2 V8 quattro B6 Saloon, Avant and Cabriolet (2003 and later) MSAU176 / 177 / 178 / 246 / 247 / 270 / 271 314 - Awaiting Production Date" Do Milltek wait for a batch of so many orders for a specific vehicle before they start production ??
