I've got two 3rd Gen Ludes.
One has a standard manifold. The other has a DC sports item.
The standard felt slightly more eager through the mid-range than the DC equiped car.
I've swapped the manifolds over as I wanted it on my track car for the extra performance it's supposed to give.
Well now the eagerness has swapped cars as well.
There's not a lot in it but it's there.

Onto the main query. Has anyone got details of the difference between the standard header and the DC item ?
Pipe sizes, bore diameters ?

I have a UK car and these are 150bhp as stock. I think they use a different header to the US model and this may explain why I'm not feeling any gains from the DC header.

I will be goping to the dyno to see for real whayt's going on. Any help in my research would be appreciated.
