anyone using an HMF pipe?

I've done a search for hmf and it turned up 0 results so i thought i'd start one
anyone running an hmf pipe or has in the past and how is it?

Im looking at the performance series brushed aluminum w/ quiet core insert and hmf's optimizer on a WRR

I have the HMF Competition Series. I have pics of it on here somewhere, but I can't seem to find them. I'll try to post new ones later.
