The titanium flame style on the list on the left side. The sound file they have is from the 4 cyl bike they have fitted it to, wont match to the GS.

I have pics too but that is the one. Brand new, never fitted on anything.

$300 and shipping. Its blue to flame, oval and it will not turn color with heat.
Slip on fit on 01+ bike, just cut the can at the flare and fit it on, adapter needed for 89-00, and I could make it and add it, but it may take a few days time. It may be better to weld the adapter to the pipe and fit the can on.

Cool.
