Milltek Performance System for Audi RS6 and RS7 C7 4.0 TFSI V8

Give your C7 V8 twin turbo the soundtrack it deserves. This UK built Milltek system transforms the character of the Audi RS6 and RS7 with a deeper, sharper note, quicker response to throttle input and a premium finish that fits like factory. It keeps your original tailpipe finishers for a clean OEM look while unlocking a richer tone across the rev range.
