bigmike1961 Posted March 11, 2015 Report Share Posted March 11, 2015 Another exhaust question. What's the OD of the header pipe on a TL125? Thanks Quote Link to comment Share on other sites More sharing options...
tlrmark Posted March 12, 2015 Report Share Posted March 12, 2015 At the start of the pipe 1 1/4 inch, at the end of the pipe 1 1/4 inch. Slightly squished down at the tight bend to around 1 3/16. Incidently the Sammy Miller header is exactly a copy of the stock pipe, except finished in chrome. Quote Link to comment Share on other sites More sharing options...
