You do realize that the stock ve exhaust manifolds designed like individual headers right? you will have about 0% improvement in performance by installing custom headers. Maybe 1 hp if you ported the stock manifolds out a little, if that.

You could try cutting up a set of stock VE manifolds for the flanges. They are thick as hell. Not sure if they are ss or mild steel though. I think they are mild as they seem to rust. But the tubing doesn't. IMHO, a set of VE headers might show gains. But I'd try to make them long tube style to try to get some low end out of them

I still have yet to realize what is so great about the stockers. Yes, they are tubular, and I guess that they flow ok, but in all reality there are many improvements that can be made. They are extremely short, unequal, don't have a proper collector, and they are smashed in a couple of spots. I'm 99.9% sure that a proper header set would make at least 5whp more. I wouldn't be surprised if there was a 10-15whp increase with a tune.

Very similar except the VE has longer runners where as the VG has about 1" long runners but is more of a log design exhaust manifold with a hell of a lot of seams and joints hanging in the airsteam of flow (crude)!

I stated they were similar, that's correct! But not that far off from each other! The only difference picture wise is the runner lenght. I'm not sure how the tubing is joined/welded together on the VE, but the VG's are crude and obstructive as hell....Pacesetter will out flow both these all day long especially once they're installed with safetied stainless steel hardware too avoid any loosening @ the spring loaded slip joints and exhaust leaks, any how...here's those VG SOBs!

Here's a fair comparison.
The 350z gains 9.1 hp and 12.5 lb-ft of torque from installing a set of headers
Here's an oem 350z exhaust manifold and an aftermarket 350z header. The oem manifold looks pretty free flowing to me.
Here's a link to where I got my information.

Exactly. Free flowing doesn't mean ****. If flow was so important, then I would make a header with short 3" primaries and a 5" collector. It's all about velocity, equal length piping, and a nice collector. Those 350z headers aren't exactly equal length and don't even have that nice of a collector.

I've stated B4! I've had good luck with Pacesetter on many vehicle I've modded here and there....My D21 Hardbody's been running this Pacesetter Header for 6 yrs now, I just recently added a wideband bung and had them ceramic coated (Polydyn)...

warning, OT:
cmax: c'mon man, you have posted at least a dozen pictures in just the 3rd gen forum, and probably more in other forums here on the org. WTF is up with the http:// in front of every single one of the pictures you post?

I never said it was a problem with pacesetter and Nissan. I said 3rd Gen VG Maxima. So your Sentra would not have any more problems with the headers than the V8 vehicle whose headers Cmax posted a pic of.

So then what was the point of your post? He already knows Pacesetter headers work fine in every application he's tried, we (i guess mainly me) are trying to tell him that the Vg Maxima ones are the exception to the rule, and you post something about a Sentra.... 
Tho based on your post in the other thread i would presume you to be intoxicated...

exactly its all about velocity and equal length piping....otherwise these guys wouldnt make these kinda headers, they will jus put the straight pipes dere..
e36 headers

i know you have. but people have also stated that the pacesetter header issue is specific to the VG maxima headers. people have also said that they had very good experiences with pacesetter products and were amazed that they had problems after all of their previous problem-free Pacesetter products. i don't have first-hand experience with pacesetter or any of that stuff.. i'm just repeating what i've read on here.

Honestly, No one has specified any such thing other than Pacesetter's good enough for a torch... and that's it...I'm not here to argue, but let's face it...not everyone should be allowed to touch tools or cars that express thier opinion here on this forum. I believe I can install these headers with certain/special attention to those spring loaded slip joints that the U.S. has used for years on our exhaust systems. If I have serious problems I can either return them under their workmanship warranty or remove the slip joints and install universal 3 bolt flanges and a flex section plus my wideband bung. I appreciate the warnings but a man's gotta do, what a man's gotta do!
ok here are some posts from the .org about the headers
pacesetter has fitment probs, this has been voiced over and over and over again. warpspeed y works as well as any other mod you can put on a 3rd gen. if you want headers that bad just pull your stock manifolds and port them out. while i had my manifolds off to drill out bolts from the head i used an air powered rotary tool to widen manifold ports. this works extremely well, taking into account the stock manifolds flow well already. as explained before, the most restrictive point of a 3gen exhaust is the stock y.
btw, have you ever heard of anyone from pacesetter ever roaming these boards? hell no. pacesetter doesn't give a f*** about maximas or anyone that drives one. dallas from warpspeed is well known here and provides good product. you're a fool to trust your money with a company like pacesetter.

the primaries for the rear head...the flange for the y-pipe hits the steering rack, hard. And everything is a bear to line-up and get the joints to seal. I'm not picking, like I said, that "guy I know" really had all that stuff happen with "his" set of pacesetter headers with jet-hot coating on them.
you know, i had pace setters a while back, if anyone remembers..... from headers to exhaust....everything but the Y-pipe...they didnt exactly fit...at all.
but right now, although its illegal, i have my complete exhaust cut off at the flex pipe, and have a resonator in that spot just to create some bckflow to keep valves from burnin'.. and it sounds like muscle <3

Yeah too bad for the VG! All I need really guys are the shorty headers! My plan is already drawn up....thanks for the all the warnings...Pacesetter should have kept their Y-pipe design similar to the factory OEM design, incorporating that awesome flex section, instead of that 2 piece y-pipe multi-slip-joint design. They were close but didn't quite do their homework all the way! I'll only purchase the cheap painted kit so I can add the wideband O2 bung, flex section and modify the culprit area....I'll have pictures and maybe a patent to sell to Pacesetter once I'm complete. Cause I got this! My boys.... Thanks....but all I need are the shorty headers!

ebay has many quality parts.obx has a decent reputation, similar to pacecetter. while I cannot vouch for either obx or pacecetter personally , they do seem to have good quality on many (but not necessarily all, see caped thread, earlier on this page) of their products.
still not greddy, or the countless other high quality brands, but meh.
anybody here given them a shot, yet?

Those don't seem to be equal length headers. What would be the gain over stock headers?
This looks like a chromed Pacesetter to me.... Not sure about pictures on the ORG since I seem to catch alot of flak over my picturial interpertations! It's definitely a VG look @ the egr fitting location.
