I just purchased a new 2006 z400 and i am trying to decide what brand of pipe i want to put on it. I am trying to decide between a Yoshimura, FMF, or a Pro-Circuit. Any input on these would be great or if you have a different brand that you think is better please let me know. Also what kind of nerf bars would be better??

 

go to kawi site. go to exhaust 400. i got the yoshi and love it. $400 rocky mountain, also got my nerfs from them, tusks-$ 100 shipped.

 

you will get so many different opinions on what pipe is good its somewhat funny.
I like the yoshi , its been good for me, the rest are good pipes too.
it all depends on how much you want to spend
as for nerfs theres lots of brands to chose from. depending if you want heel guards with them
or just nerfs using your stock guards. I have AC nerfs and DG heel guards on mine and I love them
havent had a problem with them. and as I said before it all depends on how much you want to spend

 

thanks for the input so far. Another question i have, how important is it to re-jet after adding a pipe? I hear alot of people talking about it and just wondering if it is worth it to have it done. I live in southwestern Iowa and do more "racing" with my buddies than trail riding or anything else.

 

GET RID OF THE AIR BOX LID, GET K&N(OR A HIGH FLOW FILTER) AND PIPE THEN REJETT. ONE TOOTH DOWN ON FRONT SPROCKET WILL GIVE YOU MORE TORQ ON BOTTOM END ,TAKES A LITTLE OF TOP BUT WORTH IT($12).

 

anything on how much to re-jet?

 

???

 

personally i think yosh for suzuki can't b beat, if it could, why does doug gust use it? and i like alba elite nerfs because they r anodized.

 

Yes, if you put a full pipe on you will want to rejet. If you're not riding in mud and wet conditions then take the airbox lid off (make sure to get an outerwear or something like it) and get the full benefit of the full pipe. I'm guessing a shop would charge at least 1 or 2 hours labor to rejet or just learn how to do it yourself.
