300ex questions

[bubbas300]

hey everyone! i got a 04 300ex and im lookin to jet it and put exhaust on. i will be ridin in the dunes and then the local trails. i was wonderin if any of you had ideas on what size jets to use and exhaust. the DB in my area is around 91 so im gonna need somethin a lil more mellow. any help would be appreciated. THANKS!!:)

I would shop around and ask questions. The jetting will depend on which exhaust you chose. The manufacturer will have certain specs for their pipe. I would recommend maybe a HMF w/quiet core or maybe FMF Q series w/quiet core. I would say the HMF is the better of the two. 91dB is pretty low but you should be able to get close.

i put a e-series, stock header, and a k&n and did not have to rejet. i ran fine.
