az speed and marine "short runner manifolds"
 

has anyone used them and what type of results have you gotten?

good question, I know they are not cheap either, anyone?

anyone ?

For what it's worth, I wouldn't let ASM work on my tricycle:eek:

I have bad blood from a project they screwed me on three years ago.

I think their parts are OK though, just have someone else install and tune them.
