Although its hard to say cuz no mags have done a shootout but I've always like White Bros. The FMF is pretty nice, i'm considering putting a powerbong header w/ a E-series muffler.
I heard in another forum that the Trinity pipe puts out 9hp with no airbox lid. And the price has come down $60 since it was first shown on thier website.
if your gonna wait go with LRD or Sparks pipes they usually are the best. Everyone on exriders likes em for there 400ex and they should be just as good for the Z.
i had a yosh race only pipe on my gsxr, i really liked what it did for that bike. then when i heard that you could get a carbonfiber one for the Z i had to have it. im a big fan of carbon.
