I have been up to owen developments a few times, they are very good at what they do, not used his manifold as i have an HKS one that came as a kit, he has built quite a few championship winning cars at castlecombe so can't be that bad.

I've seen the manifold on display in the display front of shop, it looks good to me, and the wastegate outlet looks nicley balanced.
As far as I know all S/s manifolds will crack eventually, you stand a better chance of owen developments honoring a warranty than most suppliers.
If that's the sort of thing your after I'd go for it, I already have a modified XS one, if that hadn't worked as well as it does I'd have the Owen D. one, and at 250 it's a great price.

I use a 6boost manifold which when you take a good look at them they have had some care and attention spent on them WRT exhaust gas flow etc. The walls are pretty damn thick so I'm not expecting it too crack.

^^ thanks- can you tell me who i would be able to get a 6boost from and a rough idea of price i should expect to pay.

If you google '6boost' you'll find plenty of info.

I had mine imported from Australia from a company called Horsepowerinabox.
