Exhaust manifold dyno results?

[madquickyo]

Does anyone have any dyno sheets to prove what exhaust manifold is better then the other? I have searched the forums for 2 days and havent found anything besides peoples opinions on which manifold they like more. As of now I have a DNP manifold and I was told that they are great manifolds but the upper rpm slacks and I should go with an Evo III or SBR instead. Im going to FP in 2 weeks to have my car tuned and am going to do the majority with my DNP, but once its tuned im going to throw on the Evo III and see if there is any difference or not. Does anyone have any proof of this being true? As I said before, I havent found any information yet about what manifold is better besides peoples opinions.

I think the gains will be so minimal it won't matter. Your tubular should help with spool up, maybe a few hundred rpms but again, I've seen them thrown on and not gain any spool. You won't see +20hp with swapping either manifold and I wouldn't buy one just to test it, unless you have loaded pockets.
