I am currently rebuilding a 2004 V 8 Discovery 2 and would like to replace the manifold with Headers to go with a new Stainless Sports exhaust. I have looked on the web but cant really find any. Anyone got any suggestions apart from custom built which are between £600 and 700 each side.

Hello!
A/ why not go to the "introduce yourself " part of the forum and do so.
B/ did I miss the "please" or "thank you"? We do respond better if people are polite.
 
Well thats a good start.
A I joined this forum some time ago(no idea when) and thought I had introduced myself.
B I asked a simple question.
 
You may have joined in 2017 but according to your profile your only posts have been these two, so no, you didn't introduce yourself.
And you still didn't say "please" or "thank you."
Most newbies do, you should know better.
 
Stainless manifolds custom fabricated usually have better flow than any off the shelf jobbies..

"edit"

It seems D2 stainless manifolds are rather scarce so i believe your only real option is the custom route.. :confused:

You can get generic "stainless jobbies" online, however the choices seem quite vague which is odd IMO..

@Henry_b, you is politerer that what I is.
I am only 4 months older than the OP and I kinda expect someone of my generation to be a bit more polite than this.
And I went to school with an Askew so it brings it even closer to home. (Can't remember his first name though, they weren't used in my sorta school!)
Anyway Asks, you've got an answer now.

So you did as stated 19 September 2017, anyway never did in 2007 when I signed in, no one said anything, different people back then... so don’t worry.

As for technical answers we will see, but I never seen anything on SS headers for the D2 mentioned on the V8 engine sub forum, there was suppliers for the early RRs and disco1 that didn’t have Cats and sold a complete kits systems, headers and pipework, for those that were doing other ‘go faster’ mods to their engines.

I expect you have already Google and perhaps not found anything applicable to you needs, have you tried Rimmer bros as they were once one supplier, maybe still.

The only mod i’ve done to my D1s exhaust is when the tail box failed so fitted a SS cat back system 11 years ago from Janspeed so worth the money i payed for a fit and forget modification, which after fitting it certainly seem to improved performance, headers and both cat are still original.
 
OP is deffo on the right track with a sports exhaust they do make a difference and generally do not cost any more at the pump.
Sports headers are just the cherry on the cake and would be unlikely to make that much more of a difference.
It don't stop us fitting them though.

In the day Janspeed used to do all sorts, don't even know if they are still going.

Well yes they are, https://janspeed.com/about
And they always used to be the dogs dangly bits, though not cheap.
OP could do worse than to give them a ring.

I don't really judge a person by their internet persona..

Doesn't really bother me too much, if my info helps.

Then it's a bonus ;) :)

So where’s you technical knowledge,?

@discool, I have given OP help and advice. I know my stuff about tailormade exhausts. Kit car builders almost always have to make up their own. I have tube bending and welding gear to make them. I also have fitted a sports exhaust in stainless to my Disco 300 tdi, so i speak from a lot of experience and knowledge.
More than you seem to have displayed in this thread apart from your usual taunting BS.
But then you know everything and I know nothing, in your eyes, so this is all pointless and even further off topic than @Henry_b and I mildly indulged in.
And you seem to think you are the thread plod anyway.
F off.
 
Thanks for the replies.
Janspeed and Rimmers dont seem to do Disco 2 manifolds anymore. I have found some by Hedman. Part No 39800 but they are for a 3.5litre V8. Does anyone know if they will fit. I asked one of the suppliers but they didnt know. The other was on e bay.at about £385 a pair

Bit of a long shot i know but sometimes manufacturers can be very helpful. I used to find this with Ford in days past. So you could try ringing LR and asking them about this question.
Failing that, it depends on how handy you are with a welder etc.
You could fabricate your own headers, it isn't all that difficult and these sorts of people will provide you with the raw materials, https://dir.indiamart.com/impcat/automotive-exhaust-parts.html
But I wonder if you might not be quite happy with just changing the exhaust system without changing the headers. If the ehaders were the be all and end all of an improved system, they would all be making them. ;)
 
Further research tells me that others have used the afore mentioned headers on 4.0 V8's and they seem to be OK. I will ask my mechanic what he thinks when I see him later. There is no great rush as the vehicle is in many pieces at the moment.
As for welding, never done any to tell you the truth however my mechanics son is very good.
It may well be worth ringing Land Rover but as this model went out of production so long ago I dont know whether it would bare fruit. But its worth considering.
As for not changing them, I cant see any reason why not. It occurs to me that one may be cracked as I used to have all sorts of problems with emisions as the vehicle got older although it was no noisier. When we strip it down we will see, as it does need some new rocker gaskets. I'm just trying to make it better than when it left the factory!

Not too suprising if the headers from older versions of the Rover V8 fit as i think they were almost machined out of the same blocks. Even if you buy them and they don't fit you'd probably be able to flog em on for more or less what you paid for them.
Don't worry, just by changing the exhaust for a sports exhaust with presumably a slightly wider bore and less obstructive boxes, you'll transform the performance. Anything that makes an engine breathe more easily is a plus, and once on it costs you no more to keep on benefitting. Unless you really have a heavy foot on the loud pedal!
 
OK so I've seen my mechanic again and we have decided to use the Hedman Headers. He has used them before and if they dont quite fit alters them to do so. We will then fabricate the Y piece to fit. It is easier to do as the engine is still in the old chassis to do the work and then transplant it into the new one once everythings done, Now just to get the rest of the chassis rebuilt!
Thanks for all the input.
As for the heavy right foot. I just potter about in the Land Rover, I have another toy if I feel the need for speed.
