Look For "the Grand Bmw R1200 Gs/gsa Guru"

Hi Friends,

Does someone would know the BMW R1200 GS/GSA Grand GURU around Bangkok ?
I look for such Thai guy who could give me some good tricks in Thailand.
Among them, I would like to get ride off the catalytic exhaust and source a direct exhaust line 2 in 1 for a GSA 2009.

Thanks in advance for your contribution.

With best regards and keep the Power On !
