Paul,
           What progress on the muffler??  .  Am I better off to manufacture the whole thing in Oz as the freight is a big item as usual.?  Also how effective is a 'fish ttail" in reducing noise ??  Had never heard of one until last night, well one that wasn't attached to a fish anyway.   Neil.

I am still working on the RX8 version of as tangential muffler.

A fish tail is good but if used by itself with a 13B it must be beefed
up to with stand the super sonic shock pulsing. IMHO it is not really quiet
enough stand alone on a 13 B. Best used with an under the cowl
tangential muffler as a second muffler. The RX8 may be another
matter as it is quieter to begin with.

Where are you Neil? We have a new subscriber in Newcastle.
