This matching pair of reproduction exhaust header pipe extensions were originally fitted to the West Coast early unit-construction Triumph 650 off-road competition models.
The extensions have an inside diameter of 1-3/8″ and measure 19-1/2″ long. An integrated support stay is welded on each extension pipe. Made in the UK.
The extensions are specifically designed for use with the 70-4884 and 70-4886 exhaust header pipes, suitable for use on Triumph 650 models from 1963 through 1970. Some custom fabricating and modifications may be necessary for fitment on some models.
The extensions are fitted over the 1-3/8″ terminus of the exhaust header pipes and secured with a clamp. The stays are located to a bracket on each side of the lower rear frame section. Some carburetor tuning will be likely when the entire exhaust system is fitted to a previously stock road-going model.
Please note: Due to varying bans on the use of hexavalent chrome in the chroming process, this item will have varying appearance different than OEM standards. Chromers are frequently using trivalent in their processes. “It’s just not the same color. Hexavalent has that clear blue sheen, but trivalent is more grayish and smoky. Trivalent will not replace the look of hexavalent.”
