I just got my powerbomb header for my yz this morning. I will be running it along with my powercore 4 squared silencer- no s/a model at Glen Helen on Saturday. I will post my impression of it Saturday afternoon

I ran my YZ 426 with the FMF Powerbomb and IV Squared silencer this morning on the Glen Helen national track. What an improvement over stock. This thing pulled hard all the way from the bottom through the top end. The most noticible gain though was the bottom and into the mid. Glen helen has a couple uphill doubles right out of the corners that I couldnt clear before. That is now history, just a twist of the wrist and the bike rockets out. I previously had the HI-Flo header pipe on, which was better than stock, but this one flat out rips the HI-Flo header. As far as it being quieter it was slightly quieter than stock, but I really wasn't concerned with the noise in the first place.

Sulley,

I ran it with 14/49 (stock gearing). I will be changing to 14/50 gearing on Tuesday after a GP that I am doing Monday. The bigger cob in back should help even more.

What number are you? I'm 918. I'll be running the OT and the Team GP with PyroTed from the WR side. If you read this look me up!
