[QUOTE="endoquest, post: 26430, member: 20816"] Thanks Trail Junkie. I spend too much time in the wet to be drilling holes in the airbox. I also use the stock muffler when I have to pass a sound test. I have both endcaps for my FMF and would like to try the straight Power Core with fatter jetting. I have a desert race in two weeks that doesn't require sound test so I'll try it then. I'm tired of loud bikes though, it's not good for our sport. Cheers BTW the FMF website says that no jetting changes are necessary for the Power Core, it does mention the holes in the airbox though, but only for the 520SX, hmmmm. ------------------ President,ETRA.
