yeah, i'd either go with the Dubach, ESR, or Curtis Sparks

you're not going to get the power you want with a quiet pipe, it works just like cars and trucks do, glasspacks give more power than turbo mufflers, same as a race pipe will give you more power than a quiet one, the less backpressure you have the more power you get.

HMF is a good choice too, the Pulse Charger would be awesome if they make them for YFZ's, probably do since that's what everybody's racing now.

 

Yeah I'd have to agree with everyone else the Curtis Sparks is a great all around performance pipe along with Dubach, but i wonder how the Bill Balence pipe is for the YFZ450 is. Also HMF is not a bad choice to.

 

get the yoshi pro system i am gettign it for my yfz and i will be racing gncc which your atv has to be less than 106 db's.

 

and the he** do people care about caps!!its not gogin to hurt you or make you mad eif SOMEONE TYPES IN CAPES NO ONE GIVES A SH*T!!

 

Hey guys, ive got a 03 Raptor Limited Edition (full black).

Just bought myself the Looney Tuned Exhaust (dual setup).. Anyone got any feedback on these pipes?

I have also purchased the GYT-R multistage airfilter and adapter plate. and now im looking to to rejet my carbys. Does anyone have a good combo to use?? I have also added an extra tooth to my front sprocket for more top end speed.

Im new to all these mods, any feedback would be great..!!

Cheers.

 

make up your mind, do you want quiet or power, HMF or Curtis sparks
