This set of Left and Right 38mm mufflers fits all 1974-'84 models* - EXCEPT R65, R65LS, R80G/S, R80ST. Uses stock or Keihan mounting brackets and either stock or Keihan clamps (each SOLD SEPARATELY). Without question, Keihan offers the finest replica mufflers and head pipes available for your 1970 and later Air-Head. KEIHAN pipes are not only built like the originals inside and out, they sound like the originals too. You get impeccable craftsmanship (noticeably better than stock!), and best of all, the lifetime durability of STAINLESS STEEL! Made in Great Britain. Keihan components will mix and match with stock exhaust parts! *NOTE: A very few bikes were imported in the late 70s - R100RS primarily - that had 40mm exhaust (outside diameter of the header pipe). If you have any doubt about what your bike has, measure!
