Speed 25 Exhaust Manifold

Postby cjt » Mon Aug 01, 2016 10:20 am


Does anyone have a sound exhaust manifold for a 1937 Speed 25 SB model to replace my badly cracked original. Alternatively, is there a firm who can repair these - although I think mine might be too bad. Or can anyone recommend an exhaust manufacturer who could replicate one in stainless steel?

Many thanks for any help,
Cliff Thompson

Hi Cliff

I use Haywood and Scott for anything like this.
Had multiple exhausts made and non have failed in any way.
They can build you a tubular manifold, then I would suggest getting it ceramic coated to keep the under bonnet temperatures down.


Think they are local to you (ish) also which is always a bonus.

I have not personally used them, but know of other Alvis owners who have used with success:
