I want an after market exhaust system for my z400, but i'm undicided between pro circuit or yoshimura. or is there better?

 

here we going again. go with hmf.

 

hmf?

 

www.hmfengineering.com they have great pipes for the z.

 

Yes go with HMF, CT or the Sparks pipe. Those are my favorite. I have the HMF and love the way the way it sounds and looks. I gave me huge power too. Don't forget to rejet.

 

Go with the yoshi, i can garuntee that you will enjoy the power gains, yout run the yoshi and a open air box with a 170 jet and you ll have a rocket. I just rejeted my buddies kfx-700 for him today and he has dual yoshi, man his ride is fast. I think i made it to fast for him. But not fast enough to beat me. We were on pavement though. But i am telling you go with the yoshi. Plus with the yoshi you can pull the spark arrestor out if you want to. Make sure you get the full yoshi not the slip. You can find a full yoshi for 400.00. I havent lost a race to another 400 yet.

 

I enjoyed the ProCircuit when I got to test it out for a while but I will never give up my CT

 

HMF-Yosh-Curtis Sparks are my favorite in that order.

 

I am trying to decide between the yosh, and hmf as well and want to know if a lot of people choose the hmf based on the price or all things considered is it the best bang for the buck? good luck bhjr75
later sparx

 

Do the Yoshi Pipes have spark arrestors in them? Because if they do I don't see the point.
