Sport silencer Audi S6 (4B)

Hello.
==References== two weeks the S6 Avant finally stands in our garage
There is even a little money left for various modifications...
I thought of a H&R coilover suspension and actually wanted to install the RS6 front + side sleepers. But the optics now remains S6 series, because I have otherwise recognized more urgent "tuning" requirements. In the interior, the engine sounds really great, it's just extremely bad that you can hear as good as gaaaaar nothing from the V8. So I really need another exhaust system. But if I look around the well-known tuners now, I find nothing that is reasonably affordable (everything well over 2000€ !!!) That's not worth it to me. After some searching I came across MSD (479€) and ESD (2x385€) from Supersprint. Still not cheap, but if I drive V8, I want and should get my environment that also-GRINS!!!

Now to my question, someone here in the forum has already had experience with supersprint in general and on the S6 or eight-cylinder in particular. All I know is that the things about Opels and one of them sound pretty good (as far as possible on these vehicles :lol: )
I read a few reviews at ciao.de, which were mostly positive (unfortunately none for the S6). In some, however, the sound was criticized. He's not, or he's barely louder than a show, just duller. Understandably, I don't want to spend 1250€ and have nothing of it except changed optics. Maybe you can help me!?!
