What's the difference between the '00+ manifolds?

[DominusEtDeusNatus]

Is '00 the year they started making different exhaust manifolds? What's the difference? I heard they are better.

They're tubular, basically headers. I'd planned on doing them, but now there's talk about pacesetters, so I'm gonna wait and see.

[Dominic]

They're not headers, theyre just designed so that its easier to change the plugs [img]smile.gif[/img] .

What's going on with those pacesetters? Any prices?

So it's just plug access? I do kinda need plug access. I can't get one of them.

So do the 2000 exhaust manifolds flow better than the 99 and below? If so, would these manifolds fit on my 99 3.8?

Which plug? Number 4 right? :mad:

They are difficult. Most you have to get under the car to access. With a little time and finger tricks you should be able to get them all.

Good luck.

I hope these much anticipated pacesetters come out because I'm dying to get some good quality headers that don't cost $670. That is ridiculous considering my brother just got some long tube headers from hooker for his Trans Am for $400!! NEW!! Oh well, I guess we can al dream right? :(

i got a set of stock 2000 headers if anyone wants em =)

How much would you be willing to give them up for? Did you notice any difference between your RK sport headers and your tubular manifolds? I'm really going for a deeper sound. I have the intake and the borla exhaust and I know headers really don't do a whole lot with respect to HP, so I was just curious on the sound produced. I'm also guessing that I would have to buy gaskets for them too right. Has any one ever put 2000 manifolds on a 99 firebird?? Any responces would be much appreciated.

I believe they flow better. The 2000+ cars do seem to pull better times stock than the 2000- cars.

This has something to do with the fact that GM started putting 3.42 &| LSD in many non-Y87 A4 cars.

Probably also has something to do with the manifolds -- which do make the exhaust note a bit deeper.

Mine is a 99 A4 and it has the tubular manifolds.... I bought it used and thats what came with it...

My car ran 14.7 @ 95.5 mph with stock tubular exhaust manifolds. ;)

stop showing off bene :D .. what times you think youd run with a set of Pacesetters or CIAs? If this mod is really that big of a difference, ill consider it..not now though...
