Raptor Exhaust / Jetting Help **Please Help**

I too would be very interested in your opinion of the Powerbomb headpipe also. I have one on order.
Sykoquadrider....the Powerbomb headpipe may be the same diameter as stock, but the so-called "bomb" (which is a cool down, ramp down, ramp up, pre-silencer for exhaust gasses) is what is key for that headpipe.

The system is somewhat loud. Not to loud for Pismo Dunes but maybe for the dunes in Oregon as I think they have a decibel limit. Maybe too loud for woods riding. I live in Nevada and it definately isn't too loud there. HMF is developing a slip in spark arrester that will not decrease hp and should be available soon. Maybe that will help.

Chris, I bought the jets offered by HMF (Dynojets) and instructions were included for type of air flow and altitude. I set them exactly as shown for my altitude and they worked perfect. I am working at sea level and I live at about 4500' I haven't tried it at that altitude yet but if what HMF says is true they should work there as well without modification. One thing to remember is to remove the air flow restriction from the snorkle as shown in the directions.
