[Zmagnette] Stub stacks

[monster at caverock.net.nz]

Hi everyone,

I'd like to get a pair of 1.5" H4 stub stacks and I've tried emailing 
Steve Ash several times to see if he would make some more, but I haven't 
got an answer from him.

So... from a light scour of the internet there appears to be two types 
available at a reasonable cost:
$32.50 ea -

$57 pair - http://www.rimmerbros.co.uk/Item--i-RL1396ALT

I've excluded the K&N ones as they are very rough, by all accounts.
Are there any others that people would recommend?

They're going to fit inside K&N filters that are 2 1/8" thick.

regards,
