By looking at your avatar I assume you have a EP3.
The manifold on a EP3 is diffenet to teh more comman 2 piece JDM ones, which most aftermarket manifolds are designed for.
I've never heard of Kidd, what sort of system is it, is it a all in one, which replaces teh cat, or is it just a top 4-2 piece, which would then connect to the JDM 2-1, or a de-cat.
With the K20 engines, the cat is part of teh manifold system, not after the cat and part of the B pipe.
So any manifold that you buy for a EP3 UKDM will have to be a special design to accomodate the lower cat part or will miss it out altogther and just connect to teh B pipe, like most aftermarket manifolds.
If you want my advise, and your thinking of changing your manifold, go for a system that takes out the cat completly, as you will get much more BHP for your £ that way. TODA make superb mani's, the DC sports one is alos very good.
Bare in mind that any manifold mods will more than likly require a remap and a aftermarket ECU, so that will bump the cost up also.
