Herers a pic of the OBX headers
Check it out.
They look pretty good, OBX claims a 12-14 HP gain with these, imagine if it was that good
They say they have them for 95-01. I am going to stop by nissan on Monday and check the gasket part #'s on the 2001 and 2002. If the #'s match up I am going to order these headers and a 2001 stillen Y-Pipe. Hopefully all this works out and I get good gains on the dyno
Stay tuned.

Just curious because I don't know wether most headers are a D-I-Y project of not. I would assume so, but I also know it can be much more tricky than it looks, right?

Sure you just have to take some bolts off and put new ones on, the problem is getting to these bolts and removing them. The bolts them selves are TQ to 22 lb's but heat and rust over time will make these bolts very hard to get off. The bolts are the same type that are on the Y-pipe but they are in a much harder place to get too. When you put the gasket on you have to TQ the bolts in a certain order, you will need a manual with a diagram. On some car's putting headers on is a sinch on others it is really hard(IE maximas).

I will be able to add a Y-pipe with these headers too

The fact is headers will do basically what all other bolt-ons do: Add high end power. No off the line power will be added, and there will be no "jolting back into the seat" from a stoplight with these applied.

Are the headers ceramic coated, crome, polished stainless, what are the runner diameters, what is the collector dia, what type of flanges are used? Am I done yet

Sorry guys, but those aren't headers for any Maxima unless it is RWD. Take a good long hard look at the headers. Look how they're offset and how the O2 bung is placed at the end of the collector. Those are NA 300Z headers if anything. There's no way those headers would bolt up to any factory or aftermarket y-pipe on a FWD Maxima. Unfortunately, there's no way headers will be effective with our Y-pipes. The primaries are forced to be way to short.
I guess I don't understand the quest for headers. Ethan has already proved that headers aren't worth much. There's been a lot of bad mouthing concerning the performance of the NZ headers. IMO, the NZ headers are of a VERY good design. Ethan proved that the stock manifolds are more than adequate for our motors. Sometimes engineers do get it right the first time. It's the Y-pipe that's the problem.

true. if there were little to no gain from those NZ headers, why would the OBXs perform significantly better?

no way these will fit a Maxima!!! heres a pic of the 300zx headers--->

Ethan, perhaps the 4th gen exhaust manifolds will fit the 2k2? From what I could tell from the FSM the heads are the same dimensions, and I'm banking on it for a future motor swap. Check and see if the exhaust manifold gaskets are the same part number, it their not maybe ask if you can look at them, you may need to open the ports on the on the 4th gen exhaust manifolds, but I bet they bolt up the same. I have a spare set of 4th gen exhaust manifolds I would lend you to check out, and if they work we can work somthing out after tha fact. You should have a spare set from the header install you did on your 4th gen? Leme know...
