ok well filled out my paperwork for my new rappy and at the dealership they didnt have any performance mods for one so i was wondering if anyone made an exhaust system for them ... my roomate has a 2005 450r with a stage 2 cam and carbon fiber yoshi pipe and the first thing i am gonna do when the rappy is broken in is race him down an 1/8 mile track so if someone had the dyno #'s for a rappy and where i can get a pipe i would appreciate it

 

HMF?

 

Trinity Racing has the Stage IV exhaust system, the Powerflow intake system, the Stage IV EFI Controller and the 734cc Big Bore Kit for the new 700. TRINITY RACING

 

there are several exhausts out

HMF
LRD
Gytr
Big gun
trinity
two bros

also there are a few intakes

gytr
k&n
uni style



also get a power commander or a dobeck tfi to adjust the efi

ebay you can find most things there

 

My Dyno runs are in my gallery

 

thx for the help i think i am gonna go with trinity setup ... does anyone know witch setup will give the most horsepower?.... and is anyone familiar with AMA rules about big bore kits? i would love that 734kit but something tells me its not AMA legal

 

With the 686cc raptor you're going to have to run open classes anyway so it doesnt matter how much bigger your engine gets.
