I wonder if he means, "Does anyone have stock exhaust headers/mufflers ?

If stock is what he needs I am sure there many available from VMF members willing to ship to Canada. Eh?

Apologise, maybe language barrier
here is the info i`m looking for
witch pass does the piping inside the manyfold,
is it a cross-over between the four exaust headers and wath it look like,
is the answer behind a grinder zip-cut :ummm:

I would say yes the answer is behind a grinder cut.
 
Ok....I havent ever cut one open....but I CAN tell you which cylinders are tied together.

On the diagram cylinder #2 is the left front, cylinders 2 and 3 are tied together, and exit on the left side. Cylinders 4 and 1, are tied together and exit on the right side. Hopefully that helps.

I'm betting all four of the cylinders are tied together inside the stock collector box.

Just a guess though.
 
Here is another pic that might help. That is the inside of the collector box.

So, like the pic shows; all four headers goes in the manyfold chamber,
we could say that exaust flow goes in a depression chamber.

It`s all at the oposite of H pipe, and X pipe.

In some literature depresion in exaust pressure would not necessarely cause power lost,
but a thing is sure; H and X pipe without manyfold chamber would get some gain somewhere in the power band.

Thank you for pic TRAUMAHAWK
 
The depression chamber or termination box helps HP gain.
-It reduces the backpressure effect of the mufflers.
-It creates backpulse waves, tuned by primary tubes length.

That s why almost all slip-on mufflers fo Vmax makes less power than stock ones (none of them has a real depression chamber)
