WB's HeadPipe

[rooster300ex]

I was wondering if the WB's head pipe is the same size as the headpipe that comes with the cobra exhaust for the 300ex. the cobra head pipe is the oversized size so i figured the WB's would be too, and does the oversized pipes use the stock exhaust gasket.

yea you use the same gasket. found out hard way and threw mine away and had shop buy new one. which i would condsider replacing if old.

you should spend the $4 and get a new one when installing a new head pipe. its a crush gasket that forms to the headpipe angle when it goes into the head. using the old gasket will probably allow it to leak and make that annoying ticking

What about the header pipe question?

[emaxxjeremy]

the WB headpipe is oversized, but i am not sure if its the same size as the cobra

sorry to interupt your thread but i was also wondering about this too except i was wondering if a fmf header is the same size as a WB header

[rooster300ex]

bump! I didn't know fmf made a header.

fmf makes two head pipes for the 400ex one is the hi-flo header and the other is the powerbomb header tey are both just headers and do not come with a silencer. Im pretty sure the hi-flo is 180 and the powerbomb is 220

[rooster300ex]

ok back to the subject. bump

Does anybody know the size of pipe white brothers use for the 300ex? i can measure mine and see.

i measured my cobra headpipe from my cobra jet exhaust kit and it is 1.360in. O.D. from the head to the can.
