Hi,
Anyone have any experience of using a Japspeed 4-2 manifold like this one?

http://www.japspeed.co.uk/honda-civic-t ... ifold.html

Does it give any better performance than the OEM manifold?

Setup would be AEM induction, RBC intake manifold, OEM throttle body, japspeed 4-2 exhaust manifold, OEM cat and some kind of 2.5" cat-back probably un-silenced b-pipe and just a back box.
Whole lot re-mapped with K100

Just wondering whether its worth changing the OEM exhaust manifold if I'm leaving the cat in?

Cheers,
David
