good V8 sound from original. Exhaust system possible [2]

Dear colleagues!

The subject has been chewed through several times, but there does not seem to be a definitive solution yet. To make clear what I mean by V8 sound, here are two left:

A8: http://www.youtube.com/watch?v=QYg2PKtqTo4
V8: http://www.youtube.com/watch?v=AI8lSIEjnQs&playnext=1&list=PL13A580D5761A5AEE

After all the sound files I've heard so far, you can't get that sound with a BN or Fox. If I am wrong, please interrupt me, because we can save ourselves the further discussion.

Tinos A8 convinces me very much, but I think that A8 cannot be transferred 1:1 to V8. This is already shown by a look at the ESD. The pictures are circulating somewhere. I would therefore like to limit myself to the D11.

I have replaced the MSD with pipes in my (D 11) so far, it has also become a bit louder (!), sounds a bit rougher when starting, but a real V8-boller is not yet. Perhaps because the MSD only contributes about 20 % to noise insulation. The rest is done by ESD. I can't detect a squeaky or tinned sound, as described by some here.
I also liked losiaks sound, but for me it is not possible to remove the cat. The newer models, of which the RS 6 offers the best sound in my opinion, show that Kats is also a good sound. So it must be possible to make our boxes speak with Kat somehow. So there were only two alternatives:

1. Modify ESD by replacing the perforated pipes with closed ones, or replace them completely with pipes (MSD is retained). Who has ever played this variant and can say something about it?
2. Complete separation of the two exhaust lines. But here I see difficulties in replacing the X-pipe (see. Annex). Can anyone say anything about this, especially if something changes in terms of performance and consumption?


I'd be very happy to hear your comments!
