I run a World Sport 2 Exhaust on my 97 LS Coupe, and for a daily driver app it is IMO perfect. It complements the DC header very nicely, and together there's a noticeable increase in midrange power. I couldn't be happier.

If you're in the snow belt, however, you'd be better off with a full stainless steel exhaust. The RSR Ex*Mag is another option, but it costs about $100 more due to it's full stainless steel construction.
