Mine changed noticeably a while back. I'm up over 7k pushing 8 now. I like the sound, but I still am left craving just a little more if not a lot more. I'm wishy-washy on the subject. One minute, I love that loud rumble, the next I think of that loud rumble on the interstate for a long multi-hour ride. I'm thinking it would drive me NUTS for that. I don't usually ride for less than an hour every time I throw my leg over my C50, and commonly, I take day long tours of several hours.
I'd LOVE to have a rumble grumble for my own satisfaction, but I get really worried about getting sick of the droning after a while. I was eyeballing some Cruizers a while back, and backed off because I thought the noise level might get aggrivating. Of course, this isn't my daily rider, and I only end up on it a few times a week at best some times. Perhaps I should let loose and enjoy the rumble.
Still, I figure I could play it safe and just drill some holes. If I don't like that, then I certainly won't like it sans baffle. Around town from stoplight to stoplight, I know I'd love it. Mostly, it's that droning steady RPM noise that I think would bother me.
I put an exhaust system on my old truck once and kept it for quite a few years. I ended up taking it off eventually because I got sick of the droning. However, that was my daily driver at the time. I hardly drive it now, so I may put it back on. Why not, ya know?
Anyways, I'm just fishing for thoughts on the highway ride. I'm not in either camp on the pros/cons for loud pipes. I'm not after performance mods. I'm not out to make people like me. I like the sound, and I won't beat around the bush that that's all I'm after with the mod. If I wanted performance, there are a million things I could do to soup it up.
