I've heard many things about them. What do you guys think? Worth it or not? Also, which ones if you do recommend it?

for the cost of install versus the potential gains...I would say...not

it's not all that worth it, but it doesn't matter.. you'll end up getting it anyways, soon or later, just to feed your addiction.

Personally I'm trying to leave open ended the possibility of going F/I, in which case headers are most likely not a great idea. That said, I'm not getting any mods that can't (or should not) be used with F/I until I have decided one way or the other.

Luckily the MREV++ V2 collector and 5/16" plenum spacer CAN be used with F/I... which is why I'm willing to get them (thanks Hydrazine).

If you know for certain, 100% that you're staying N/A, then I agree you'll probably do it eventually.

However, if I knew for certain, 100%, that I was staying N/A, my first mod would be a 3.9 final drive gear...

I love mine. Costs a lot to do it, but the power boost and the sound (Oooooo, the sound ) makes it definately worth it

I can tell you week after next when i get my Strups installed

I think if you can get a good price on the headers themselves and especially on installation (or have a super patiance and midget hands) its surely worth it from what ive heard and seen.

Most say that they feel a noticable increase in performance, and do dyno 5-15 extra ponnies depending on other mods.

If you are staying N/A then headers are worth it. It took 7 hours to install them with the car on jackstands.

Headers will give you more power gain than any other bolt-on NA mod, but in terms of bang-for-buck, it is not a good value. Is it worth it? That's an individual decision. Figure on $2k for good headers, thermal coating and installation. You could install yourself and save a bundle, but the install is a B1TCH!

Race against me tomorrow and decide for yourself if headers are worth the expense and headache:

I felt the biggest gains from headers. I gained power everywhere in the power band. Especially in the mid range. Like everyone else has said, if your staying NA then they are worth it.

Especially if you don't plan on changing out your stock cats. I am staying with stock cats because of all the threads I've read about running lean, rasp, cracking pipes, rattles, CEL's, etc, from hi flow cats and test pipes.

Installation isn't rocket science it is just very time consuming and annoying to do. Lots of scrapped knuckles and swearing. Keep in mind you can get a set of Strup headers for @500.00 and a set of gaskets for @50.00. So if you install them yourself it is a very good "bang for the buck" NA mod.

Yes. STRUP is my choice.

no leanness, rasp, cracks, rattles, SES, etc... from my high flow cats ^_^

The majority of cracks are usually associated w/ aftermarket y's or older models

The rattles are generally from models that needed 'modification' in order to fit

SESs are generally from test pipes
leanness is generally fomr test pipes

rasp is generally when it's been paired w/ certain aftermarket setups

All of it can be explained. HFCs have the least drawbacks.

if you go the turbo side then no need but if you go to SC then yes

Your right. I've heard there are far fewer problems with hi flows compared to test pipes. But I have read many posts about problems with hi flows as well. Cats failing internally, cracks, exhaust too loud, etc... I may still get a set one day but I want to hear them on a similar setup as mine before I get them. Plus, I will do a before and after dyno to make sure I'm not running too lean with them.

If you can do the install yourself I bet they are worth it... most of the shops around here want $400-500+ to install them in the Z b/c its such a PITA

Just got my Nismo headers installed this week.... worth every penny.

ISMSOLUTIONS

Love my DCSports, Fast Intentions Resonated Test pipes and exhaust - man the sound is unbelievable!

Well - the Stillen CAI and MD 1/2" MREV ++ didn't hurt the sound either!

And the 3.92 GEARS!!! The car is a monster!!! Then again...cams and heads didn't hurt either

NA all the way....
