Hi Flyfisher, the cat is the same length and fitting as the Morgan standard cat, but some cars require an extension pipe. These are available from Harpers. Best to check if there is already an extension fitted or not.
The Cat length is 32cm measured at the outer end of each flange.
The connecting pipes are 4.5cm.internal dia.
Female at one, Male at the other and they are offset.
The flanges are 3 bolt at 6.5cm. centres

The cat is Stainless steel.

Hope that helps, John K
