Alright guys I need some product review advice. I see yamaha has that GYT-R header pipe for the WR's, but is it worth it or should I go with another brand. Any insights will help. Thanks fellas. and ladies.

I recommend the FMF powerbomb SX header for more bottom end power. :thumbsup:

Once again you have been of help Indy. Thanks a lot man. One more question for ya. Do you think I would have to change the jetting at all if I added a powerbomb header. and if so what would I have to change?

It is a realy subtle change.
One size larger pilot , #40 leak jet and raising the needle one position should do it from your current jetting. Main jet will stay the same as you normally run. :thumbsup:
