Hello all, am just curious how the Dr.D titanium stacks up. I have a street legal '06 wr450f that I think previous owner built from ThumperTalk 'cause it has all the mods listed here. I absolutely love the bike. Never had a Dr.D before, it came on bike so I have nothing to compare it to. Is kinda loud, but not as loud as the yoshi on my LTR450.
