Oh believe me, I'm aware of your plans. I've seen the equipment. I'm going to try to be present at the track for these goals this year.
On another note: I might order these and fabricate to fit. Someone else on here has ordered them and said they look pretty good and cheap!

BTW.. How good are you with electrical wiring? I have EU on my mind right now, but thats a secret.

Almost looks like a resonator or something. I'd probably have to cut that out of my set if I got one and replace it with straight piping. These also aren't meant for a 3.0, but we could certainly make them work without a whole lot of problems, unless they just suck like the y-pipe on the OBX.The question becomes how good of quality are they? If they're going to be junk after a single winter of driving I wouldn't want to waste my time with them. Also, I need to see pics of the welds and what not before I can truly consider the possibility ordering them or not. Who was this other member who ordered them? Get them to post a thread up!

Is they are the XSPower/SSAutochrome, then they are VERY good quality. Only problem is the ypipe hits our damn crossmember

If I see this correctly, the front and rear collectors merge into one smallish 2-1 collector and then expand into a flex section. The pipe just after the 2-pipe merge looks pretty small, then expands into the flex. Not generally a good thing. No EGR tube, either.
My first question would be how do the headers fit into the Maxima - especially around the motor mounts - then where does the Y-pipe fit? Is it too low for Maximas?? That flex is too far forward to work right, I think - the flex would be under the engine.
The pipe after the flex seems bigger ?2 3/4" OD? That could be OK if everything lines up, but the O2 bungs need to be moved and there seems to be two choke points in the tubing at the 3-1 and 2-1 collectors. Oh - always use OEM engine gaskets - they are framed in metal.
This set would not be my choice if high performance is the goal. Find somebody that has installed them and get pictures - I could be F.O.S.
They are pretty, though.
Yes, I do electrical stuff - you didn't see the basement lab. Shift_Fast_3 is under construction down there.

If you do OBX, I know an exhaust shop just a few blocks away...

A few more up-the-shirt headers shots
While changing out the Mobil1 oil, I took a few more shots of the new headers. Just a few more details for your viewing enjoyment.

Note the long 2-1 collector going to the turbo flex. No restrictions there.

You can see the black NX nitrous 6AN pipeline at the top, when it goes into a 6AN-(2)4AN Y-connector.

Makes you wonder how I'm going to get a third stage in there, doesn't it?
It's always funny how the track Tech inspectors always stall out at the nitrous wiring. Fully fused and connectorized for almost anything. Too bad. Heh...
Anyway, I found my problem with the fuel pressure thingie.. Since I have the original rail fpr still connected, and I found a vacuum leak in the intake manifold gasket, the fuel pressure was being dragged down by the OEM fpr. Fixing the intake leak made it all better - the Aeromotive FPR worked as before. Yea !!! I'm baaccckkkkk.......

As Advertised - 3" cutout is installed!
I just got back from the exhaust shop, where the owner welded in my new stainless 3" cutout. Looks pretty good..
A few other shots before:

Last night I sprayed the Beast with both stages of nitrous, and it revs like never before... I smacked it up to 100 MPH very quickly once - geeze, that second stage kicks you in the back and holds you there.
It hits fuel-cut almost immediately in first - takes a few seconds more in second - too much Mother's Day traffic to extend it further. Geeze.

EDIT - I think I need an aluminum heat shield up against the body, to keep the hot exhaust off all those lines you see..
Another good reason to keep the nitrous line INSIDE the cabin, eh? Roasted nitrous line for dinnah! Yum.... Boom !!

That welding work looks very good. Those obx headers are looking better after the pics.

Actually I can schedule a dyno day right now, with the old shift_fast manual shifter in there now. I'll check with 5th Gear and see what they say.
I'll PM you if I can get a date. I'll need more race fuel - I have a couple of full 15lb bottles sitting around - that should do it... and check the trailer thing, too... (sometimes I break things)....
That might hurt your times because you'll be too distracted to drive your best.
