My ZX14 had the Brock's Ti full system. Loved it. If you don't want to go the full system/performance route, I'd go w/the Akra slip-ons, or the TBR (Two Brother's Racing). The TBR usually has a great sound and look.
There's all kinds of stuff you can do to the bike (Simple stuff.) to improve power, especially down low. Great bike!
