need help fmf fatty on blaster

[MC17X]

I just picked up a used fmf fatty pipe for my blaster, The problem is it did not come with a flange, How does it mount up to the cylinder?

[CSR400EX]

the pipe i bought for my old blaster came with a flange and springs and such. sounds like you need the flange for the FMF pipe. try calling FMF to see if they could sell you one or contact the person you bought the pipe from and see if he forgot of has another one.
