Off the top of your head how much is a new set of down pipes and the small connecting pipe to the silencers? Just had them polished and they look am-az-ing! Like they just came outta the factory. Not cheap though but double checking against the cost of some new ones.
You get them on fleabay fairly regularly, some new as a complete new system is a popular mod on a new bike but mainly they seem to be used but in good condition. Prices range from £40 to £200 This set of scruffy looking ones were at the £40 end of the scale. http://www.ebay.co.uk/itm/Triumph-B...D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557 And these are at the upper end but of course there's no guarantee they'll fetch the asking price. http://www.ebay.co.uk/itm/TRIUMPH-B...303488?hash=item23813fe480:g:pokAAOSwhQhY3kSo
