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.

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

Nice one David - have you thought about encrusting it with diamonds ? 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 ??
