You can get an OEM head pipe
HERE for less than $80 if the dealer decides not to give you the pipe for free. If nothing else it saves you 3 hrs of driving.
As for the HMF being "worth it", I suppose it depends what you are looking for. You cannot run the HMF without a fuel controller of some sort. They offer one, which I have on my machine, that modifies only the fueling. For the cost, you would be further ahead to get the PCV controller from Todd if you choose to get the HMF exhaust. If you are not concerned with adding power, and just want a stock replacement, then get the OEM headpipe, and a tuner from Todd. That would be the safest route for the least money. You can always upgrade the exhaust later if you choose.
