I have been thinking about getting a z400, but i have ridden one and its just not quite the power that i want. Nothing against the stock z but i am just a very competitive person and i ride w/ a lot of people w/ raptors. So i wanted to know what is the best pipe system with the greatest gains. If anyone knows where any dyno curves are that would be helpful.

Also any other "power-up" ideas could be appreciated.

 

put a pipe on it and jet it then hang on.............

i smoke raptors all the time, yeah they might eventuly get you in long run (400yrds). But at any drag strip you can usaully only shift into 4th. The raptors is better if your a bigger guy i think.

 

I would recommend either a Sparks or Yoshi for a full system, but an HMF if a slip on is the way you opt to go.

 

z400's NEED a pipe to be competitive with anything. But with a pipe they will smoke pretty much anything. I would suggest the yoshi. Just saw one in the dunes piped and jetted and pretty much toasting banshees of all things. I think with yoshi, k&N, and jetted, a z400 kicks all ***...
