Went mudding this weekend in my Raptor and got REAL muddy (look at my pics) and now my head pipe is brown, any way to get it off? I think Im going to send it over to jet-hot in phoenix and have them coat it, maybe I can pick up some hp?

 

I see your E-Series broke exatcally like mine! They must have problems with them at that weld. I just welded it back together and sold it. White Brothers should fix that!

 

I think the vibration caused that. The welds looked pretty weak too, I called WB but they took like 2 weeks to answer so I just had a friend fix it.
