Found some headders for the 3.4 for only 200 bucks! They cxarry ceramic coated ones for just over 300. www.texas-speed.com . I wonder if they'd work on the 2.8, 3.1 too?

 

if they are for a 4th gen camaro or bird, they will fit but require some bending as i understand it. the will bolt up to the heads though if that's what you're wondering.

If the 3.4 manifolds will bolt up to a stock Y pipe, why wouldn't the headers? I assume the 4th gen owners don't go out and have a Y pipe made when they put them on. There is less space around a fourth gen V6 motor then around the thirdgen..... why would it need extra space?

 

there are differences in the firewalls, and teh y-pipes are routed differently between the 3rd & 4th gens.

PLus, the headers usually come/the matching y-pipe.

 

How come I can drop a 3.4L in my thirdgen with the 3.4 manifolds, and have it bolt up? (you know, I'm seriously thinking of designing a set of headers for 3rd gen V6's....) If anyone can tell me where to get a 3 part collector, or whatever the thing is called that joins the three pipes? lol

 

To answer your question: YES the 3.4 will bolt in, the manifolds on that 3.4 will work as the outlet of those manifolds exits in a location where the body of the car does not interfere with it.

The 3.4 headers you are looking at were built for the 3.4 when INSTALLED IN A 4th GEN CAR.

Look at any headers and you will see they take up more space in an engine compartment than manifolds, in this case, the 4th gen 3.4 headers hit the firewall of the 3rd gen cars.

you can heat up the headers for a 4th gen with a propane torch and then bend them to clear the firewall, so they WILL fit with a little work.

Then you can take the car down to a muffler shop and have them build you a Y-Pipe.

 

the ones he posted a link to are shorties...
so, we need to get a pic and see what they consider "shorties"

 

PaceSetter makes street legal headers for the 4th Gen 3.4
I'm hoping to be leaving in a few days to go to Phoenix for having street legal headers made for the 3rd Gen & my car used as the mule for that purpose.
"Mule" is an engineering term for the "mock up/fitment".
With the street legal headers for V6 in 3rd Gen, one will also need purchase the better flowing "Y" pipe. This "Y" pipe will also be made by PaceSetter
Contact
Fgerle@pacesetterexhaust.com to express interest in this product for our 3rd gens running V6.

All the stuff from the 3.4 motor will fit under hood of 3rd Gen. The 4th Gen 3.4 mnifolds are nearly 99% identical to the 2.8/3.1 manifolds. There is ZERO increase in flow with a 3.4 manifold, it's as lousy a design as the 2.8/3.1 item.
The 3rd Gen "T" pipe sucks as a design for performance, any way ya look at it.
Look down your engine bay passenger side exhaust system to see why.
What can ya do to the factory 3rd gen set up?
NOT MUCH.
Add a better flowing Cat Convertor, increase the rest of the pipe size to 2 1/2" & add a better flowing muffler.
IF ya want to keep factory exhaust manifolds, it's not so difficult for an experienced muffler shop to create a better flowing "Y" pipe for our 3rd Gen V6 ride.

If ya stick a 3.4 under your hood, as I have (twice) the original vehicle factory "Y" pipe bolts back up just perfect, with no modifications required.

 

was wondering where you went with the header stuff...
