My friends got an 04' Z and he loves it. He just purchased a DG Stage 3 Xcellerator exhaust, and a power pack kit (kn filter,jets, outerwear, adapter,cleaner) and its sweet. Its got so much power increase, and top speeds around 75 mph. Plus, u can adjust the nois with the spark arrestor.

 

The Z is a awesome trail bike, it has the soft suspension, and more power than the honda 400. It's fast, but I don't think It will go up to 75, try more about 69. A pipe and jet kit wont give you top end speed, it gives you more faster acceleration.

 

68 to 72 mph.....

 

doesnt this fourm make it so obvious that wannarace and fastestblaster are the smae person lol.
