Attention Southern California Triumph riders, British Customs would like to develop a new exhaust for the Triumph Thunderbird 1600 and we need your help! We would like to use your motorcycle for a period of two weeks to develop and test a shorty slip on exhaust for the Thunderbird 1600. Once the production phase is complete, the selected motorcycle will receive a free set of the completed exhaust as a “thank you” for volunteering to help us out!  If interested please contact us toll free at (877) 999-BRIT
