I am a happy and proud owner of either a Royal Star Boulevard or Royal Star Tour Classic with four (4) exhaust headers and mufflers. I am living in Thailand where big bikes are taboo, but here as a gray market offering, most bikes coming from Japan. The serial numbers are removed and restamped by the Thailand Department of Revenue so I am not sure of the year, but I did own a 2000 Royal Star Boulevard in the US that I purchased new. I want to install some aftermarket slip-on mufflers but am not having any luck finding pipes due to the age of the bike. Any help would be appreciated.
