in the medium term I'm after a stainless steel exhaust for the 6 (cat-back). A decent sporty note, some burble on overrun would be nice to have and I don't mind if it screams on full chat, but else it should'nt be much if any louder than the original exhaust setup. What's more important is that it must not be more than 5 db louder than original at idle and cruising at 30 mph or else it would not pass the approval test.
What I read so far is that Jetex should be quite silent. What about Blue Flame? I did not find out much about it. An oval, original-like exhaust tip would be perfect but round is also fine. I don't like these 100 mm waste pipes though. What is your experience and which system can you recommend?
Thanks,
Michael
