On a stock cube ls1 heads and cam with full boltons, what would make more power? Dual 3inch cutouts after the headers or a true dual system with a x pipe and dumps?

Thanks

true dual system like the tsp rumbler x. you get no scavenging with cutouts after each header opposed to a true dual with an x pipe for scavenging. my friend just put dual 3 in cutouts on his ory pipe and he said he felt no difference other than the fact that his ears were ringing all night.
