Moderator Airhead Posted February 4, 2011 Moderator Share Posted February 4, 2011 that would explain the strange looks in granbys when i asked what they did in the s&m range. it would liven up a quiet moment. Mine has a SM tailpipe though the sticker is long gone, as a matter of fact I think you could get the with different badges at some stage. SM was Serval Marketing, just a name on a badge, as in made by someone else. Back to the topic I can get a full set up imported for £34 inc postage sounds good to me...?
