There are plenty of well-built exhaust systems that will accomodate a turbocharger at some point without being obnoxiously loud. The GReddy EVO2 cat-back is a good example of a civilized, effective and legal exhaust.
I have to agree with Dave on this. Law enforcement do not appreciate this at all. Doesn't matter if your local laws are strict or not, those of us who enjoy this crazy hobby as responsible drivers gaulk at those with LOUD exhausts. Maybe it comes with maturity or whatever, but basically...stay away from loud Exhausts. Greddy EVO II or APEX'i World Sport Exhausts are good and not loud at all.
