I have a set of exhaust pipes that fit a 67-68 TR6C - the high pipe version. They are in very good condition. Chrome is very good. I just cleaned and polished them so they are gleaming. .They were fitted to my 1970 and I replaced them with the appropriate year pipes. Can send pics if interested.
The mufflers are sold. Still have the pipes - and they are officially for a 1966. Someone corrected me that the slash cut were in 1966. I confirmed it in the parts book. The PO said he bought 68 pipes and mufflers. They fit the 67-68 but are not straight cut like the proper version.
