Which is the best YFZ pipe?

[WORCSYFZ199]

I was wondering what the best Full System exhaust pipe is for the YFZ, in terms of Torque, HP, smoothness (of power), and if you can convert it to a quiet pipe? any info would be great, thanks.

pulse charger or rossier. IMO

the n-motion is supposed to be be pretty wicked. low-end of a TC, and with good mid-top power too.

Sparks, Rossier, HMF are all good

i have a rossier coming in the mail soon, I will let you know what i think

For MX i would go with the Nmotion. I had a Sparks before and the Nmotion has a ton more power on the bottom

Thanks for the info so far guys, but I was wondering on the Nmotion one can you make it a quiet pipe with an insert or something?

I'm gonna be doing some races where there is a sound limit of 99db so if I could find something that gets within a couple db of that it would be good, but then I could change it back to the louder pipe when I dont have sound restrictions.

The Nmotion has a quiet core you can buy
