the kid with the mohawk helmet Posted March 17, 2007 Posted March 17, 2007 I know before i wanted my bike to stay stock but now i want a pipe on it. Has anyone tried out the new pro circuit pipe, or the new white bros carbon pro. I know ragdoll mx has the dr.d and i rode his bike and it had a good sound to it but im looking for a good souding pipe that puts out a lot of power. The only pipe i dont like is big gun, cuz there sound like pepsi cans welded together but any other pipes any good. Quote

EY3BA11 Posted March 18, 2007 Posted March 18, 2007 Dr. D all the way.. PM ragdoll mx on here and get a run down of what he did to his bike... it runs like a raped ape Quote
the kid with the mohawk helmet Posted March 20, 2007 Author Posted March 20, 2007 I know mxragdoll has a dr d full pipe, cams, and a i cat i think thats all. I rode his bike omg it was amazingly fast. I think if i did cams, pipe and hc piston i could maybe beat or hang right next to the cr500's Quote
EY3BA11 Posted March 21, 2007 Posted March 21, 2007 He has Full pipe, Hot Cams Stage 2, I Cat, and Quickshot accelerator pump cover. Quote
rcjunky3 Posted March 21, 2007 Posted March 21, 2007 i would agree with dr.d after all they are the ones who do r&d work before yamaha puts out a bike or quad and they are factory riders. so one would think they should have the most insight on yamaha products Quote
the kid with the mohawk helmet Posted March 21, 2007 Author Posted March 21, 2007 Well i know from factory a yamaha yz450f is exposed to have some where between 49 and 52 hp stock. So i figure a full pipe/intake/jets around 6-8 hp gain. Cams maybe 4 and hc piston like 4-6 so maximum gain could be somewhere around 15-18 hp. Thats just estimating. So that could be around if true a stock 450 has 52 hp it could come out to 70hp so we will see the building wont start for a while but maybe soon with just a slip on or new k&n intake Quote
EY3BA11 Posted March 21, 2007 Posted March 21, 2007 you better put your bike on a dyno and be prepared 15-18hp on boltons hahahahahahahahahahahahahahahahahahahahahahahahahahahaha 6hp tops with boltons if your lucky! It may feeeeel like it added horsepower all your boltons do is move the powercurve around it doesnt add much. Quote

EY3BA11 Posted March 25, 2007 Posted March 25, 2007 Of the dyno sheets... PROVE it cuz im willing to bet your friend was lying thru the giant gap in his hillbilly front tooth! Quote
wingnut Posted March 25, 2007 Posted March 25, 2007 Of the dyno sheets... PROVE it cuz im willing to bet your friend was lying thru the giant gap in his hillbilly front tooth! And even then...every damn dyno will give you different numbers........I could give a sh*t less what a computer and a sheet of paper say about HP. Quote
EY3BA11 Posted March 25, 2007 Posted March 25, 2007 This is true!! damn correction factor.... dyno's can be fudged in so many ways it not even fun. Quote
the kid with the mohawk helmet Posted March 27, 2007 Author Posted March 27, 2007 Well that sucks damn i was kinda excited now im just wondering if i should stay stock, well for now at least. HMMH..... I might just stay stock and pick a cr500 up next year from the guy i was going to buy one from before. Quote
EY3BA11 Posted March 28, 2007 Posted March 28, 2007 Once you start modding a bike down goes the reliability... I have had the same bike for 4 years and this year is the first time i actually had to drop some form of money into it (60 master cylinder). Ride it like it is and be greatful you have a bitchen bike! Quote
dccd45 Posted April 26, 2007 Posted April 26, 2007 I put the GYTR exhaust on my 07 450 I noticed a difference i like it Quote
