Anyone know where I can obtain a stainless steel exhaust manifold for my Elan S4 at a reasonable price? Noticed Paul Matty sells them for ?375 + Vat - seems a bit expensive…
Try Sue Miller, i think she had standard size stainless ones for about 120. Was Paul matty’s a larger bore version?
Yes I think so - I assume this is significant?
The Matty item is newly designed and claimed to fit without any problems…
Looks nicely made, but also a nice sum of money!

Stainless steel for the exhaust manifold is not such a good idea. Due to the vibrations that the old twinc generates the stainless manifolds tend to crack in time. Just a word of warning.
And stainless tends to be thinner and therefore noisier.

I think I got one of the first off their new pattern.
I bought one of the previous pattern (at Stonleigh last year!) but it was a very poor fit.
Took them until September this year to get the new one to replace it! In the interim I have used my old cast iron manifold to get the car going.
The new manifold looks fine but I haven’t tried it against a twin cam head yet…
If you need a picture, dimensions or anything just let me know.
As an aside to this discussion, I have just dug this out from an old Mick Miller parts list. I assume this was his opinion:
“We have found that the best combination of durability and pleasant sound can be achieved by using stainless steel manifolds, Y piece and centre pipe, together with a mild steel silencer. We can supply stainless silencers, but we think you will quickly tire of the harsh sound.”

My Sprint has a stainless manifold and system.
The noise is a bit harsher but not what I would call excessive.

My exhaust system is exactly the reverse of what Mick Miller recommended - All mild steel except the rear box and it sounds fantastic.
I would respectfully suggest that is the way to go, as more condensation occurs the further from the engine you get and as I would imagine most of our cars are not in daily use, the silencer is first to rot with acidic water sat in it for long periods of time.
My S4 has a stainless twin silencer exhaust and mild steel manifold, secured in position by the manifold and standard strap at the rear of the car. While it seems rigid, I have read that some Elans had a gearbox mounted securing bracket. Was this the case for the S4? If so, are these available?
