differnce between the Sparks X-4 and X-6

[partyboy300ex]

is there a differnce between the sparks x-4 and x-6 pipes? I have been wondering about that

x4 slightly more bottom end than x6.

x6 slightly more top end than the x4 and a little less bottom end than the x4.


most people get the x6 for moded motors and the x4 for stock engines.

im pretty sure the x6 is for big bore motors like 370cc and up.something like that:) the x4 is for motor under 345cc.check out their site

the x-4 will make more power at lower rpms, the x-6 will rev higher and prefer high rpms. both make great power on our 11:1 416 motor.

it depends on the cc's of your motor. anything under 350cc's, get the X-4. Anything over that, get the 5 or 6. if you have a 400EX. get the X-6.

Basically, it has a larger diameter head pipe so it flows more air. Bends may vary some, but it's mainly diameter.

And yes, the x-6 is made for 370cc and up motors. the X-4 is perfect for a 330cc 300ex.

For your 426.. if you want more torque (XC / MX) I'd go with the X-5 personally. If you want more top end power go with the X-6.
