Buddy of mine has a 2003 scrammy 500 4x4 with k&n filter.. he wants to get the white bros. e series. does he have to rejet? does he have to do any clutch mods? and any info on how the disks work on the white brothers e series.....he wants to just give it a little more umph to it with little changes as possible......... he is looking in the rocky mnt. catalog..and he is gonna call Rick Ritter....[img]i/expressions/face-icon-small-happy.gif[/img]

 

I didn't have to rejet with mine and i left the all the disc in when I had mine on. I no longer have it on though.

 

why did u take it off? any problems with it?

 

No need to rejet with the WB as long as you dont add too many discs.No need to reclutch if you dont want to but you will see real gains if you do clutch it.

 

reclutch with the white primary and violet secondary from hpd .. and whats to many discs before rejetting.?????// thank you

 

the amount of discs that comes in it is about max if youre adding a filter. more than a coupe added you should jet it.

 

No I had no problems with it just that it is a bit on the loud side and too many people where complaining so I took it off for a while. IT works really well though.

 

yes i agree with you the pipe is pretty loud. with all 8 disks and the end cap on it sounded like a cobra exaust imo. i had to remove 3 disk to get it at a ok sound. im not sure what others sound like as i have not heard them. i also did not rejet. and i like the pipe. btw it is considered spark arested soo if say i left 8 disks in can the nahbiors still call on me? i have some nosiey ones.... and can i ride it on public trials? i belive it can only be so loud or does it just have to have the stamp of us forestry app?

 

Is it more quiet with less disc or does it make it louder? I have all mine in with a spark arrestor to make it more quiet but it didn't do much.

 

the more dics added the freer flowing and more noise.

stork,
it depends on where you ride, most all require the spark arreseter and be within 94-96 dbs.
check with your local DNR.
