Extractors to fit a Stage 1 v8??

**stage one** · 26th April 2010, 09:46 AM

Hello, been a while, I was hoping I could get some insight on which set of extractors will come the closest to fitting my stage1 V8 series 3?My left hand cast iron header is about it fall into 3 or more pieces, just like the last one. After a bit of a look around it seems all left hand v8 manifolds have more or less self destructed. So with this in mind, I have decided to make the leap and go for extractors as well as make up a whole new improved functional exhaust system. My ute is currently 100dbs in the cab(ear plugs are recommended PPE), it tends to resinate off the roof, I might stick foam to it and see what happens. I have heard that Range Rover extractors will fit with some modification, are all Range rover extractors the same, and how much is “some modification”?? And I also ponder which brand are most likely to make a difference & last, I like the look of the pace maker tri-y design, as for some extractors seem to just be an excuse to bend odd lengths of thin wall tube into a dogs breakfast. Well thanks all!

I cannot help with the question - my 101 v8 exhaust is different again - however I do believe that I saw some v8 extractors on ebay a couple of days ago - do a search and you might find they fit.

I just fitted the cast twin down branch manifolds of an efi V8 to my early Range Rover. It made a noticeable if not huge improvement over the original cast single pipe system. The advantage is that they are cheap and much easier to fit that tubular headers. P38 manifolds are tubular also but at a glance they appear to be pointing toward the firewall like the sd1 whereas the older ones go straight down. We have a 110 v8 and the efi ones look like they will bolt straight up to it with the obvious extra plumbing to connect the manifolds to the rest of the pipework which would have to be done regardless of which system you use.

I recall from my Stage 1 ownership days that Range Rover ones don't fit & at the time they had to be made up specifically for the stage 1. The later manifolds would be a good option.

Rick Perry used to make them 25-30 years ago, but Perry's are long gone (who bought them out ? ) which doesn't help you much.

Just caught up with mate who has a 110 V8. He just fitted the efi manifolds and downpipes like i did. They bolted straight up and as the stage one is bloody near identical under the bonnet to a 110 v8 then they should go on easy. He says he has noticed quite again in low down power and generally its smoother, sounds great too.

I personally favour this idea due to much lower cost, much easier to fit and they are a very good design. Headers will not have significant improvements over these on a 3.5 and as far as I know they are still used on the 4.0 disco2.

I will have to look into those cast iron disco headers again. Had a look at a set a while ago now and was a little concered that the right looks totaly diffrent to the left, I guess that shouldn't really matter. May be the best, or only option.

Where abouts are you?

I currently live in Emerald Qld (for the last 6 years), makes part shopping a little tricky!

Looks like HM Headers took over/merged with Perry Exhausts.
HM Headers | Home

Back in the seventies/eighties both companies developed systems for the 4WD market.
Rick Perry had a huge range of headers for all the then 4WD makes, and I remeber HM doing a similar thing, there was a evry good write up when I was a kid of HM developing a system for the G60 patrol, starting off with a dual system/dual outlet and ending up with a large bore single system, showing how and where power/torque was gained/lost.
I fitted Perry headers on my first car, a Jeep CJ6

If they still have the old jigs around they could still build a pair of pipes.
