Exhaust velocity? Ok, my lack of car knowledge is gonna show here, so brace yourselves.
As we know, properly oriented V8s (can) have true dual exhaust, manifold/headers feeding to a single pipe on each side. X-pipes and H-pipes are used to equal out pressure and velocity, right? So my question is, how messed up is our exhaust flow, the front goes down, then up through the cross over, then back down to meet the downpipe and the exhaust that's already flowing properly out the back? Is this helping kill our performance or am I just a complete idiot and over thinking things?

I'll play devil's advocate here, the difference in distance is only going to be present upon initial start up. Once pressure is built up in the system either bank should be equal pressure.
Keep in mind the pressure we are talkng about is "back" pressure, not the amount of pressure they are producing but how much is built up to push back against them so once the system fills up with exhaust the entire system should be "pressurized"
