A7_TDI_BlackEdition

You could spend £1,200 on this Kufatec system and cut/ weld the ends on and fit the wiring loom. Please do it and tell me how easy it was and what it now sounds like. I dare not try first https://www.kufatec.com/en/sound-booster-pro/vehicle-specific/complete-kit-active-sound-incl.-sound-booster-for-audi-a6-a7-4g-40222

I have been looking into the same thing to no avail! My post is on Audi-sport.net and there have been some suggestions including that Kufatec system for £1200. Seems very expensive for what is basically the last part of the exhaust and you are expected to cut and weld it into place! Another member who has an S7 had an aftermarket exhaust fitted that sounded nice but I am looking for the v8 rumble on demand and something quite for the rest of the time. I spoke to Lincoln Audi who said if I gave them the reg of a BiTdi they could try and find the exhaust part number and special order it. Havent gone down this route yet as I think it will be mega expensive and not sure if it will come with all the necessary cables.
