Thanks for the input gang. I have had a couple of Leo Vince, one on a Grand Vista, other on a People 250. They are excellent exhausts for sure. i had an all stainless aftermarket (forget the name) on my TGB Delivery 150 and a super light GPR slip-on on my beloved Silver Wing (RIP, pic below). The GPR was a bit too free flowing.
I also performed a rework on the stock exhaust of my '08 KLR650. The Leo and KLR rework gave the best results overall. A Leo would be very nice but honestly, I don't want to spend $300+. i can get a new exhaust on my car for that. Hey, we all gotta make a living, but i feel these aftermarket scooter exhausts are over-priced. The technology and manufacturing is not that difficult. OK, yes, i can be a tight-wad so rant over............
Anyway, i am also considering adapting an exhaust can off a motorcycle that would have a similar exhaust pulse. As an example, one side of a dual exhaust off a big twin like a BMW R100, Ducati 996, Triumph Bonneville, etc. As it would be one side of the exhaust, it would be from a similar piston size and configuration. As i weld, i can adapter pretty well. i was hoping someone had already been inside the Xciting 500 exhaust can and could give some insight of the interior. But who knows. Maybe i will flip for a Leo or a MIVV if I loose interest, or time, for taking a can opener to the stock exhaust.
