Hi all, Have looked here enough to have learned that I should probably change exhaust, fuel, and air all together, or pretty much not at all. I have a stage 1 air cleaner standing by, but know not to install it until I'm ready to do the fuel along with it. But I don't have the fueler yet. Wondering if I can get by with changing exhaust only for a short time and maybe as much as 2,000 miles, then changing the air cleaner and fueler together at the same time. The exhaust I have in mind is the D&D Fat Cat, regular baffle. Or should I ***really, really*** just wait and do it all together? That won't kill me - - but when I change the exhaust, I can also change the clutch cable, then I can tilt back the handlebars I already changed (but can't adjust the way I want until I have more clutch cable) - - - etc. So it's about more than just being in a big hurry for some more noise. But having had 3 drivers shift over into my lane in less than 6,000 miles -- I'm ready for some more noise, too.
