I think these would be perfect on the S6 where you have the V8, but no turbos to tone down the rumble.

Which Miltek system do you have. Way back Miltek had a 3 inch turbo back race system; DP's, no Cats, no resonators, just rear mufflers. I have that system with a pair of 100 CEL Cats added and it is acceptably quiet around town but very noticeable under hard acceleration. It is also quiet enough at cruising speed to prevent annoyance over several days driving.

It's only hardware and that configuration from anyone should work well. Only unknown is your local emissions laws and noise regulation. It isn't that quiet under a heavy foot.
