Hi, I have an original Honda F1 Muffler /Exhaust. The chrome is excellent & it was removed from the bike quite early on in it's life & replaced with an original Paul Dunstall exhaust.
I have the original pipes too, which are 7/10 for condition. the bike currently has a Motad after-market system on.
I'd like to put the original pipes & can back. Inside - from the engine end, the can is good, light atmosphere induced rusting, no "rot".
From the 'exit' end, the more finely perforated tube is fairly corroded - soft, in fact, in places, but still there !
As far as I can seem, from checking the Parts Fiche, unlike some other models the F1 muffler has no servicable internal 'end tube' ? It seems a crying shame to not use the can. Has anyone any experience of overlaying or cutting out & re-rigging the internal perforated pipe ( or just running it to / past destruction? ). I'd grade it about 5/10 - or better, in terms of degrading at the moment. I don't want to make it worse un-necessarily, or ruin what life is left in it by hacking it about or reducing it's effectiveness.
Or is it servicable & I'm just missing how ?
cheers
