Need info on a free flow exhaust system for Milano 3.0L

[Mihail Baba <mihail@domain.elided>]

Hello,

Soon the time will come to replace parts, or whole exhaust system on my
Milano 3.0L
It is still in very good shape, except for the muffler which has couple
of tiny holes.
Instead of just changing the muffler, I would like install a complete
system with a good performance and sound.
My question is: What is available and where to get it, also I would
appreciate any tips, impressions, etc.

Thank you!

Mihail
