HMF vs. Dubach 400EX

[04TRX400EX]

So I have been told by many people that HMF is the way to go for a 400EX. I was talking to a guy at the Honda dealer that also said Dr. D was a great pipe for the quad. No one really talks to much about Dubach though. What do you all think? Are they close in performance?

I still think HMF is the better choice. It fits the powerband of the 400 better. I've ridden a 400 with a yosh, wb, and mine with a HMF. The yosh was nice, and the power band was smooth, but it didn't have the torque of the hmf. The wb was also nice, with more power than the hmf, but I also saw that it's mount was cracked. I love my HMF. A lot of torque, and it fits the bike so nice. The mounts are actually of quality too.
