Header Question

I am thinking about getting headers for my 3.4l 94 Camaro from http://www.redlineperformanceengineering.com/1208.htm
What i was wondering was do you think me and a friend could install them, because I have got mixed feedback on that and some people have said they have big problems installing them. Also i have got mixed feedback on the performance gains from headers on a v6. Some say i will lose hp? If you could help me out that would be great! Thanks.

you will not lose horsepower. Those stock heads or w/e u wanna call em that are on there now suck. They restrict way to much airflow. You will be able to tell a difference in sound and performance.

As for installation, i have no clue

I was thinking about putting headers on mine too, but decided that the gains just weren't worth the price and the trouble of putting them on. I just don't think that our engine will gain all that much Hp having them on.

yea, im just not sure about installation, my friend works for Bmw and has access to alot of stuff welder etc, but i just don't know complicated it would be.

well its not all that bad.... its a pain and i was bleeding, stressed out, and didnt want to see my car for a week or 2 but.... well worth the trouble... im sure anyone that is mechanicaly inclined and has some car knowledge can pull it off.... (from a v8's standpoint) v6 is probably even easier

Well this is right up my alley since I've already put those same header on my bird. I would honestly never recommend those. In fact, I heed warning about them. Look at the picture of them. You see the right side header.. now look at the middle pipe. That pipe bends down at about a 45* angle. Which leaves you nearly no room to put any kind of header bolt in. I had to have an exhaust shop cut my header bolt down to half the size (mind you, it was already 1.5" to begin with) just to clear that middle pipe so I could get it in. The design of those are terrible, and are just not worth your money. It took me nearly a month (working on it here and there and on days I wasn't working) just to finally get those headers on so I could go to the exhaust shop to get my cat-back welded on. Absolutely rediculous. Not to mention the headache you'll get from trying to get the old manifolds off. Which requires you removing the alternator, the accessory bracket it sits on, and pushing down the a/c compressor down as far as you can without unhooking the lines. It definately requires ALOT of patience. If I didn't have my friend there to help me out, then I swear I would have never gotten it done.

So my recommendation and advice..
1) If you're looking into headers for your engine, then get the RKSport ones. Haven't had any experience with them, but they can't be half as bad as Pacesetters.
2) If you're short tempered or not very mechanically inclined, then I'd suggest getting you're friend to do it. Plus, he's already has the tools needed to get the job done.

As for the performance gains.. You'll notice the gains immediately after you get into your car. It'll sound a whole lot better, and take off a heck of alot quicker. IMO, headers are well worth it. Despite others negative outlook towards the 3.4.

In fact, as soon as I get a little more money saved up, I'm gonna take my car to the dyno and see what she's puttin down. I'm hoping for around 210-220 hp. Odds are it's not gonna be impressive to most people, but then again.. I was never out to impress anyone anyway. Just trying to do something different and change others outlook of the 3.4. Some people call that engine slow, some people call it puny.. heck, some people even call it a pile of crap. But I tend to call it.. working with what I've got.

Im sure with your friend who works at BMW and has access to stuff itd be pretty easier than done at home. You wont lose HP, whoever told you that either is trying to stop you from doing this to your car or is an idiot.

its possible to lose hp when puting on headers... that's usually involved with a really crappy designed headers, that are too big, or to restrictive... also sometimes has something to do with the pcm and sensors, because headers are louder, sometimes the pcm reads the noise as knock, and will retard the timing... causing you to lose hp... like i said it can be too big as well... too big as in it doesn't direct airflow enough... just like if you just unbolted your exhaust manifold and tried to run it with the exhaust ports showing, you would lose hp that way because the airflow exiting the port is not directed away from the port in any way... the header could also be too small in that it chokes the exhaust gas and causes it to not flow easily....

those ways of losing hp usually don't happen with headers... headers will almost always yeild an increase in hp, because designers don't usually make them so terribly that they would zap hp...

as far as installation... you probably will have to put them in from the bottom, don't know if there is room to drop them in from the top...

I don't understand what it means when it said the headers were for the 94 3.4l Camaro w/o air, what does w/o air mean?

It means either air tubes for emissions (there little tubes that are above each header tube) or o2 sensors? Either one of the above no sure... kinda braindead right now.

a.i.r is the emissions air tubes for the A.I.R. pump that connect at the top of the header/exhaust manifold... unless you can program A.I.R out of the PCM then i would recommend that you buy the headers w/ the air, its more expensive but you won't ever have to worry about the law getting on you about emissions...

the headers should already have bungs in them for o2 sensors so don't worry about that...

The 3.4L's don't have AIR systems in them. They must have made a typo. Just ignore that part.

Oh, and also on their site it says "Catalytic converter must be relocated." That's not true either, so ignore that as well. Those headers are a direct fit replacement for the old manifolds. No fabrication required. Although I still don't recommend them, but if you insist in getting them, then I would suggest you also went to Napa, Discount, or Autozone and picked up a new set of gaskets. The ones those headers come with are flimsy little cardboard type ones that wouldn't last you a week before they started to leak.

hmm... that's news to me... i didn't know that the 3.4 didn't have an A.I.R. pump... learn something new everyday i guess
