as shown, yes. but i didn't feel like spending all friggin night making the diagram perfect. 
it would be narrower in real life.. and the bends would be smoother too. that's just for the general idea of how it would be.. i just didn't have anything to make non-circular bends with on powerpoint.

Youre not far off the original stillen design for the 4th gen:
I really wanted to mod my WSP, Im sick of the drone. Thankfully OBX just came out with equal y headers for the VQ. You guys are SOL for equals, so call up Cattman or WSP to get these mass produced!

that's an idea... the junction being vertical instead of horizontal... but you're right that is fairly similar to what i was gong for. just without the upstream 02 sensors. and a slightly more relaxed bend

The only problem is mass production requires mass demand. I can't see Brian Cattman being interested in producing these. WSP might, but I doubt it. Maybe if they get deposits from people. :shrug:

I really like the stillen design and I thought about making my Y-pipe a little more like it, but it would have been more cutting and welding.
Does anybody know if a vg manifold will bolt up to a ve? I know the vg exhaust ports are round and the ve exhaust ports are oval, I just would like to know what else is different about the flanges. For some time, I've been thinking about trying to make the vg obx headers fit my ve. I don't think the vq headers would work on a ve because the motor mounts are in a different location.

)equal length exhaust matters because if you have different-length pipes, then the exhaust pulses will hit each other instead of coming down the pipe at even intervals. if 2 exhaust pulses hit each other, you add resistance. then there's a space where there are no pulses, which is time wasted.
same reason performance vehicles have crazy headers like this.. so the pulses come out evenly

shut up w/ your rice crap. takes one to know one anyhow... this dude did something good here (also idk understand = "i don't know understand".... )

......the red part is 100% right and plus they make equal length to match the frequency with their designed muffler...not if u put after market muffler and cuz then frequency changes and tone of muff changes too and then it directly effects the back pressure to go up and down... and as far i can tell by the design of 505max94se...he probably have gained a lil low end...
edit: did u check how many lbs of back pressure u have now 505max94se?

well, i really didn't mean to sound like a downer. you've come up with something new, and you have noticed an improvement. nobody expects the first attempt to be PERFECT and you should be proud of what you did. but like any prototype design, a few tweaks will usually make it even better. and don't mind burhan.. he's learning...... i think.

Nice. Sick.
Did you try turning the wire-speed down? to the lowest setting? or if it's like mine- until the wire will jam up if you don't have the ?liner/cord/gun? perfectly straight.
No I was using gas but for some reason it kept wanting to burn through on the lowest heat setting. I was using a Lincoln Weld-Pak 175HD. Normally, I can weld better than this even with flux. It looks like **** but it doesn't leak.
Actually I was welding a little more like Jeffy
Your exhaust is now on Jon94se's Maxima.

honestly...do you care what others say? you're driving your car every day...so why do you care? YOU like it...who cares what others say.
it's new...people will be a little negative about it. personally i'm not a fan...but can't say that it's not a good attempt....so i didn't comment except for the welds.
