That one actually sounds pretty decent. The first one from the facebook post was pretty harsh and brappy but the one Olbilford posted was much less so, tone was pleasant and didn't seem unbearably loud.
At the risk of turning this into another science experiment (hey, I'm a retired engineer...), if it's a straight through pipe, albeit with some packing, is that such a good idea? I was under the impression these bikes liked to have some back pressure for better exhaust scavenging and torque. I know from experience straight through pipes on a Harley are a piss poor idea, maybe help a little high end but not so good for normal riding. Does the existence of the packing somehow provide the desired back pressure?
For the Harley muffler currently on my G5, there is a plate blocking the flow at both ends of the can (well, in some distance from the ends), forcing the flow into and through the packing. I've drilled a hole, probably 3/4" currently into each of them to get some additional tone and breathing, but still provide some back pressure. I will likely do some additional experimenting (going a bit bigger), although it seems to be working well without sounding obnoxious as it is. Probably would keep the Harley muffler on the G5, but considering the Globe for the C5.
Tim, I see it looks like the back section is removable (for repacking, I presume). I'm not a fan of the Globe nameplate which appears to be riveted on - if I picked this up I'd drill them out but it would leave a couple holes, obviously. Is the spacing of the screws on that back section such that it could be rotated so the holes wouldn't be so apparent?
