Just asking really,
So after reading and watching a video explainging X pipes and H pipes, and learning that an X pipe isn't purely for balancing engine sides but also causing a vacuum/pulse and better flow through the exhaust and also stop scavenging, my question is...
Does the middle box alone be good enough for the system or would an X pipe actually benefit?

Unless you have developed everything else then x-pipes, balance pipes, crossover pipes etc etc etc are pretty much pointless….
Its all about a series of improvements..
Most people but big brakes on std cars. 4 pots over 2 pots are fantastic to talk about in the pub……….
build the car and get it out there and enjoy…Most other things are purely pub talk.

I agree 100%. My car was fitted with Wilwood 4 pots and ventilated disks which imho are not needed for driving on the road. Just the pads cost a fortune and squeel terrible. Ventilated disks also expensive and for me not needed.Its all about a series of improvements..

I should have bought a pair of 16P calipers and gone back to solid disks.
Maybe i could change back and sell the 4 pots to a boy racer

What people forget or don't grasp is that there are two things going on with exhaust activity that matter here. There's the flow of the gas (the speed at which the particles move through the exhaust) and then there's the "bow wave" - the pulse that moves faster than the particles themselves as they knock together and propagate the moving pulse to make a noise per "bang". These move at different rates and this is important.
With a V8, with an H pipe (and I would guess to a lesser extent) an X, they help to cancel out the moving bow wave and help reduce noise as they can push towards the other bank and get cancelled. In my experience this works well when the H is near the manifold and gets a "clean" pulse from each side. It should help with scavenging too.
I used a shared box from both banks and exhaust was too noisy. I fitted an H at the ends of the manifolds ahead of the shared box and it made it considerably quieter. Whether it made any more power or torque... I don't know, not enough to notice anyway.
If you don't have a separate bank (not a V config) then the cancelling of pulses isn't an option so all you can gain by merging the exhausts in an H or an X are that the gas can take the lowest resistance path from the point at which it sees two routes to the rear of the car.
My two cents...

well said, so many people think an exhaust is just a garbage shute!
