I know what you mean about the restriction issue. I've tried to keep a balance between fuel, air and exhaust mods. My gut feel tells me I'm too restricted on the exhaust side, and I've got a drill bit extension to put a hole or two in the last(?) baffle, BUT, I'm afraid they may be too loud. So, I'm leaving well enough alone for now. How much louder than stock? Well, stock from the dealer I couldn't hear much of anything. The very first thing I did was taking out the first baffle. Sound was not good, and then as I messed with jets, airbox, needles and baffles, it started sounding and running better, so I just kept going. Not too scientific...but it runs pretty good. I think I've got just about the right "rumble and volume" I've wanted, if I'll just leave it alone!
