Which header do you reccomend? I have a bored out wr400, so a header for a WR426 might work better for my bike. Is the FMF Powerbomb the best?

I have one on my 03 450, it may give you a little more bottom end but it is definetly quieter. :)

I went from stock to a Powerbomb SX. More bottom end, but I am not sure it was any quieter.
