e-series or fmf??

[RIKR4X]

MY BIKES ONLY MOD IS A 14 SPROCKET, I WANT EITHER THE E-SERIES OR THE FMF AND WHICH FMF WOULD YOU GUYS RECOMEND? THANK FOR THE HELP!!!

[trueblue450]

300 or 400EX?

I hear Curtis Sparks has an excellent pipe. And is a better price than both FMF or White Brothers. So I'd look into Curtis.

E-SERIES ALL THE WAY

[yamaha1470]

i would go with th e-series

[MichaelS693]

Curtis Sparks or Supertrappp BUT what are you lookin for sound power what?

[RAPTORAZ]

E-Series with 18 discs and a 165 main.

[400exBro]

e-seris all the way not as loud as FMF and over 15 discs puts out more ponies than the fmf. i have tht slip on and run k&N filter and 160 main with a 42 pilot jet for nice startings.
if you want to mod the engine later on you might want to buy the slip on and then a power bomb header but i dont know if those two will fit together.
E-Seris rules

THANKS FOR THE HELP!NOW IS ALL BIKES DIFFERENT OR SHOULD I BUY A 158 OR 160 MAIN ? AND , SHOULD I PUT A 40 OR 42 PILOT .

[400exRacerX]

It all depends on the elevation you live on.

[Wheelie]

Try a 40 pilot and a 155 main.

[BANSHEEadam]

It's 299 for the Curtis Sparks X-4. I would look into that.

Anyone know where to find the true specs of different exhausts?

[400exBro]

if you got a 400ex try running a 160 main K&N filter 4 holes in the air box 3rd notch on the needle(i am running 12 discs) and i am running a 42 you could also run a 40 but i need a 42 due to the cold winters here in canada. hop this helps
