I bought a c5 rs6 with decat and full Miltek res. MRC tuned to 550ps. have now roved the back boxes and run strait pipes from the small center res. small drone at 2k but godly noise at 4k when you lift off. Gives you a slight metalic amg sound then burbles and back fires on overrun. Under general driving it's not too loud round town.

It's the constant motorway drone that will make you want to murder puppies.

They sounded pretty good on motorway WOT too :thumbs:

Remove Resonators - Louder in the car, little louder outside
Remove Back-Boxes - Little bit louder in the car, very loud outside, more mid-range V8 noise.
Remove Both - Women faint at the burble, men instinctively recognise the presence of an ultimate alpha male, children will hero worship you. However, everyone's now deaf.
Remove Both plus no cats - As above times infinity!

I went with the back-box delete only and added a bunch of vids on YouTube. I kept the resonators as the car drones at motorway speeds (quite badly to my ears) but if you can deal with that then definitely remove both (like Bam had).
Hi there,

sorry for reviving this thread. Do you still have the videos of your rs6 with back box deleted? I can't seem to find them and I am looking to do the same to mine

Iv got standard exhaust with centre box delete at the moment. Not loud at all and barely changed the note from the exhaust. So I have now ordered some sport cat down pipes hope fully increase power and sound🤞🏼
