Milltek C7 V8 4.0T Centre Box Bypass Mid-Section | S6, S7, RS6, RS7 | MSAU570REP

Want more V8 presence from your C7 without changing tips or downpipes? This straight-through middle section replaces the centre box on Milltek’s cat-back system for the 4.0 TFSI V8, unlocking a deeper tone, more volume and a sharper throttle feel while keeping everyday refinement. It is a direct swap for the Milltek centre section, giving your S6, S7, RS6 or RS7 the soundtrack it deserves.

We have installed this part in-house and customer feedback has been fantastic. The result is a richer burble at idle, a muscular growl under load and that addictive overrun character enthusiasts want, all while keeping the premium finish and fit you expect from Milltek.
