Guys, I bought my 2004 WR450 in Feb of 2004 from Lake Hill Motors in Corinith, Missippi for $5400 OTD. What a deal!! (My way of promoting a great deal, www.lakehillmotors.com ) Any ways, I used to race when I was a kid, skipped the 250cc 2 smoke class, and the last bike I had was a 1996 CR500R (Didn't race but what a MULE!! I kind have this need for speed. ) which I carried from Missouri, to California (Bakersfield), to Eagle River, Alaska until I let it go in 1999. I have been reading ThumperTalk.com for about 2 years now and would like thank all of you fellow WR450 riders out there for your free mods and friendly advice. I am not a young pup any more so I thought I would get something a little more manageable to go ride with my two young sons. I will admit that at first I was disappointed with the power of my WR450 :D . I finally got off of my over worked and busy butt to do all of the mods and then some. What a hughe difference!! No sh&t!! Those out there that says the free mods are all BS, are full of BS. Thank you!! Now, what aftermarket pipe do I need to light this rocket? Any suggestions? I am looking towards FMF and there new exhaust line up.
