Damn bro. I cant wait to throw these headers on with a nice set of lumpy cams and a nice exhaust... That second video sounded awesome, I can hear the increase in smoothness from the equal length.
More pics would be awesome, if you have some.

No sir.. Bolt right up. The only thing i Had to do is shave the crossmember a hair just like the 5thgen guys. I could have gotten away with it but i just wanted piece of mind. The O2 sensor locations are perfect too so you dont have to have em re-drilled. My rear one is located right by the bend. Will post pics up 2mrw!!

correct.. My 4thgen only has 2 of them downstream and the obx headers had 3 iirc so you wont need to get them relocated just use the one further down stream for the rear manifold the one up front fits like a glove.

so wait...does the y pipe disconnect at both headers? like this..
or is the rear header and the y pipe one big piece? If I can remove the y pipe separately then I want me a set of these! How much did you pay??
we are talking about long tube, equal length headers here, for under 500 bucks?

what do you mean "not quite"? are you referring to that rear header not being full length? I dont know if the picture I posted is what the OP bought, I just found that on the OBX website.

I'm just saying, the headers are hardly "long tubes" and I doubt they're true equal-length (the primaries, not the 2 downpipes). I'm not saying they aren't far better than the current cheapo ebay "headers" we have available now, but they're not exactly the end-all, be-all either. Merely keeping your enthusiasm in check
But I really don't see any other headers available to us ,short of cattman, that are even remotely similar to those. They have the long tube primaries and the equal length design (even if it isnt EXACT 
). Besides fitment tweaks and perfections, what more can we really ask for? I don't think anybody is going to come out and engineer something outrageous for us, and if they do it'll w/ be cattman prices.cattman: (for 02-03 max's)
OBX: (for 02-03)
unfortunately the design still has the rear header and the y-pipe together.

it wouldn't be a big deal if someone would just sell a damn equal length y-pipe in the first place.

Oh, and I think you're totally misinterpreting what I'm saying about the headers. I'm not ungrateful for them, nor do I think it's a terrible design. I just think you're wrongly using the term "long tubes." Seriously, that's it, that's my whole argument with you

NO! LETS FIGHT DAMNIT!
nah, its fine. I need someone to point out when something is too good to be true. I wasn't TOO excited about it. I'm just looking at them in the sense that these truly are the only header/y available to us that incorporate the features of the Cattmans that are so highly praised (and aren't actually Cattmans).
anyway, hopefully I'll get some of these within a few weeks, I need to re-do the whole exhaust.

I got my own. They are like 4bucks a piece where I got them from. make sure you plug the one by the firewall before installing the headers because after installing the headers, Its a pain to get to.

Just make sure you take your time. I rushed at first and broke a stud. Imagine the horror. But after I I took my time it was a breeze. The front one is cake the rear one was a pain to change but I also have the 00VI so changing it from the top with teh manifold was also bad but I got it.

I'd wrap these or get em ceramic coated. These have thin tubing and S/S as it is likes to let heat get away. Lost heat is lost power.
Sounds awesome though, like the cattman gen I's. The gen III's didn't have as sweet a tone (haven't heard enough of the gen II's to comment).

Dang, I've been searching ebay for these, but haven't seen any for a while.
How was the removal/install on the rear header? That is the only thing I am worried about. Did you have to pull your engine or drop the crossmember? My Maxima has 180,000 miles on it, I hope the year header isn't rusted on too badly. I also have an 00vi, did you have to remove it to get at it from the top?

Oh, thats just a graph I found somewhere. I haven't had mine on the dyno yet. I just have it switch at whatever feels the smoothest by the seat of my pants. Seems like right at 4800RPM its smooth as butter and I can't even tell something switched in the manifold.
