Exhaust mods

[Hartless]

So I'm thinking of doing my Own exhaust system. Plan is to rid my self of the collector system and have a two in to one on both sides. Front left to rear left and right front
To right rear. Has anyone ever done this or heard of this being
Done? I need to figure out jetting and such and not really good at it!

The spec2 exhaust has this setup. Front Cyl to left, Rear to Right. Search this forum for pics. 
No Jetting is required that I know of, but the spec2 headers are close to stock for pipe gauge, and use the stock Y piece at the rear.

I'm not sure that's what Adam is describing unless I'm reading it wrong. It sounds like the front and rear cylinder's left exhaust valves will feed a left muffler and the right valves to the right muffler. The rear cylinder will not use a "Y" but rather have separate header pipes exiting left and right. Is that what you are proposing Adam?  Do you have a running Vision to hang this yet unmade exhaust on?

Oh.  Sorry Hartless I was half reading it on a small phone.
I've never heard of that setup.  What do you see as the advantages?
