You seem to have drawn a blank on this request 3reggy, I guess Mr Honda makes fairly robust, long lasting exhausts and tail pipes for the Jazz. Only owners of Mk 1 & 2s may have been unlucky enough to have had parts of exhaust replaced before needed due to catalytic converter thefts or normal wear and tear.
I would be interested to know if any Mk 3 Jazz owners, particularly 1.5 Sport, have fitted performance after market exhausts such as: HKS, Mugen, or Spoon, and whether they were worth considering for a not too annoying improvement on standard muted sound, even though power improvement is probably very limited.
