Mike, what model year is that particular TR6 "SS"?
I ask because I just Googled that model designation and the only thing that I could find in reference to the "SS" part of it was this question posted on another website's forum about such a machine....

http://cgi.ebay.ca/Triumph-Trophy_W0QQit...%3A1|240%3A1318Both of these "SS"s came up as model year 1963, so at first I thought maybe that designation as only particular to the 1963 models, but later I did see some other references on the web to the "SS" in other years such as 1958, '63, '65 and '66, so maybe my first thought here wasn't correct.
And seeing as how that "bone stock"(as the seller advertised it on eBay) one had lower exhausts on it, I doubt that the "SS"s designated high-piped models.
