Im new here and I would like to have your opinions on which exhaust would make the most power
for the yfz 450.I cant seem to find a web site that will give hp numbers for the curtis sparks exhaust but I know its a pretty good exhaust along with the hmf.Any other suggestions would be nice.

 

anybody please I need your opinions and thoughts!

 

well from what i have been hearing and seeing about the pulsecharger pipe is the one to look at for the yfz450.stock hp is 37.5 and with the pulsecharger their getting 45.8hp .everyone on the other yfz forums are saying its the best overall power pipe for the 450.

 

I know when i get my yfz450 i will be buying an HMF.. Here's how much the HMF adds.

CLICK ME!!! NOW!!!!

 

ctracing.com go down to yfz 450 the pipe kit on there 32hp to 48.2 hp

 

Thanks everyone but the price on the pulsecharger pipe and ct pipe scared me away but I like the performance for your money that the HMF full system offers and It makes pretty good power down low. Does anybody know of a website that has the Curtis Sparks exhaust with hp and torque numbers for a yfz?

the HMF makes 9 HP in the midrange.. but it aint HP that gets you going.. it's the torque that gets u off to line... and hp keeps u in front..

 

if you get either one you wont be dissapointed i promise
but if i were you i would get the sparks
there are a couple problems with the sparks pipe
1 no kickstart cause it wont clear the pipe
2 they dont have a removeable endcap therefore no spark arrestor

there are two types of sparks pipe though
the normal pipe
and the big core which is overall bigger in diameter everywhere it is a top end pipe for like drag racing and mainly sand

 

Sparks, HMF if you have sound issuses, because they have a quieter core, I think it brings it to 94DB

 

Tell me something I dont know lol like hp and torque that the sparks pipe makes and what is the db of the pipes Curtis Sparks makes for the yfz.
