Flexible exhaust

Has anyone had experience of this type of flexible exhaust with
the Honda engine?
The flexible pipe bit, not necessarily the can...

My only thought is that the convolutions will tend to disrupt
the airflow, probably be OK for short connecting pieces.

Would you need some kind of reducer, as the exhaust manifold on
our engines seems very small?

It seems to have an I.D. of 25mm, which the standard exhaust has
a flange from the manifold bit to the silencer that is about
that. I am tempted to try it for the price, just wondered if
anyone had had a go with it.

I tried it and found it reduced performance

Would also think it would need extra support either side of
flexible area ?
As our Wee little single cylinders are rather prone to
vibration ;D. Last year before deciding on current design (see
two braces/support brackets) , i broke a couple pipes at the
flange .....thank goodness for welding kit ;)

Thanks Applejack. I suppose you could have a sort of expansion
box....a sort of big area in the spare space of the boot, with
an outlet to the outside of the car, so that there isn't that
sudden back pressure, which I suppose is the problem?
