Vixen exhaust manifold
Discussion
Looking to replace the Vixen exhaust manifold. I'm not willing to spend £800 on a blingy stainless jobby - just want one that does the job effectively. Off the shelf items are all for old Fords (Anglia's or Escorts). Burton power offer a mild steel Ashley design for £205 or an ebay one for £100.
Has anyone purchased one of these and modified to suit a Vixen? Is it possible / practical? Or is there anything on the market for a Vixen at a similar price point? Mild steel is fine.

I modified an escort item (think it might have been an Ashley) to suit my Vixen. Tedious rather than difficult job. There's not a lot of space to work with and it's a bit of a step in the dark when you make the first cut but after a bit of buggering around and tack welding you can get a route through then weld it all back up again.

If you give me a call there are three of us here in kent getting Clive in the Isle of weight to make a stainless version of my OE one.

Clive has the patterns from mine and Pauls - you may need to use a drill file on the manifold flange though I think he uses an Austin 7 head to mock it up on....Andrew

Ford x-flow... Austin 7 what's the difference?!?!Or is there something going on here that I don't know about?

Wow, that is rather beautifully made isn't it.So would it be easier to buy one and modify or buy a manifold kit and build up?

Thanks Andrew. That looks to be the same as what I have removed.
In this picture you can see my old manifold together with a new Ashley 4-2-1 and 4-1 (ignore the 4-1 one as I've ruled it out). Although very slightly larger bore pipes (1 1/2", 1 3/4" & 2"), the 4-2-1 has identical primaries and similar outlet. However as you can see the secondaries are quite different. This being :
1) the upper end of the secondaries are twisted so that the pipes lay one above and one below, where as on ours they are side by side
2) the secondaries immediately slope diagonally down to the outlet where as on ours they travel horizontal before diagonally down to the outlet.
As my engine is still in the machine shop being rebuilt, I'm trying to determine whether this manifold may be a workable starting point. However I can't recall from memory how much clearance there is around the secondaries. I am pretty sure (1) won't be an issue and should actually give me more clearance from the engine & chassis rail. But regards (2) I am wondering how close the original secondaries are to the bell housing or starter motor.
I don't suppose you could take a look at yours and either photo the clearance around the secondaries or just post me back with some details.
Cheers Moto

|https://thumbsnap.com/ba88gHfT[/url]I'm not sure the design of my manifold will help you Steve. The primaries on my manifold look similar to the 4 into 1 design that you have rejected. My manifold is a four/two/one and was made for me by Maniflow in Salisbury. It may look like mild steel but it is stainless, just not highly polished and apparently according to the guys at Manilow not as brittle. There is plenty of room until you get down to the secondary pipes where space begins to get a tad limited. The shape and form of my manifold is a close copy of my original manifold, except in larger bore pipe. Unlike many I've seen, the primaries do not sweep upwards above the level of the exhaust ports before sweeping down. I presume those manifolds constructed with the up-swept primaries are designed like that to balance the length of the primary tubes?
Andy. I like the look of that. Interesting as it's design seems as though it may allow the gases to flow though more easily than the design of mine.
The only reason I'd rejected the Ashley 4-1 was that the bore's are much larger at 1 5/8" and 2 1/4". Fine if I had 185bhp but too much for my more modest motor. If it had the same bores as their 4-2-1, I would have probably gone for that as again the design seems as if it may flow better.
Where did you get yours made? It looks as if it cost big £'s ??

I can't remember how much I paid for the whole system. They have a web site: http://www.maniflow.co.uk
Test fitted the new one today all looking great.
Wont fit fully until i strip the back of the car and fit the new uprights quills etc and clean up the chassis and sort the slave leak on the Clutch so a weeks work when i have some time over Easter and get her ready for Monaco in May,
