YES, I did a search first.

I see revhard makes a manifold for the ka and also found jgs, who makes the parts for custom manifold.

Question: who has a revhard manifold and is it worth the extra money? and for those who have "home made" manifolds, have you had any problems with it and how is it working out for you?

Oh ya, what size turbos are you running on these manifolds?

Later

 

if you do a search on ebay there is currently a rev hard manifold for 3 something hundred. don't remember exactly though
