Yoshimura or FMF with the cherrybomb and uni or k&n airfilter. I need some good feedback, I heard good things about the fmf 4.1 full system but other ppl have told me to go Yoshimura. I want to make a good decesion I want whats best for power but sound is also a nice thing too. I want loud and power what should i go with. thx for feedback.

 

Why do you want loud? Anything loud is not going to be good.....

I'm sure the FMF system comes in under 99db, not sure about the Yoshi but I've heard they are louder.....

The AMA/ATVA are down to 99db right now and there is word that they are dropping to 97db in the next year or two.

 

loudest on the market right now is the Big Gun exhaust. It has decent dyno numbers, type this ( Z400 performance pipe dynos ) into the search and you'll get some good pipe info. I'm personally going with the White Brothers Aluminum Pro II.

 

1st off, loud and power don't ness belong in the same sentence anymore. the new quiet pipes are producing as much HP.
Yoshi all the way IMO. My daughter was running the FMF last year. She switched to another pipe and the power was way better. Matter of fact, after the switch, she went undefeated.

 

i agree with lt80 yoshimura is the better way to go and thats what i run on my 2006 z400 and 300ex and defiantly K&N

 

I agree with ss..louder is not the way to go in this day,especially with riding areas being shutdown and goverment restrictions tightening on our sport. PLenty of quieter pipes that are making good power numbers available. However, in this case , for me, hands down....the Yoshi! Dont even need to ponder that one! Good luck with whichever you choose.

 

Most of the Yoshi pipes I've heard are not as loud as most. I think..
Am I incorrect?
Tell me about it guys.

 

I would tend to agree with that. They definetly arent as loud as LRD,HMF, or Big Gun, imho.

 

From what i've read and heard from people, most prefer the yosh of hmf

 

Yoshi is what we run on the KQ 700, quieter and lots of power.
