MOSS SS MANIFOLD

[WoodyMaj]

Has anyone fitted the Moss Stainless Steel manifold to their Series 2? (Part no 27-5024)
Frustratingly their Accessories catalogue has a price of £198, which was clearly too good to be true, whilst their website price if £448....

Hello and welcome to the Forum.
It would be helpful if you put your name in the footer section of your posts.
The subject of exhaust manifolds has been "exhaustively" discussed on the Forum over the years. A search of the Forum topics will give you a better idea of all the pros and cons involved.
The general consensus is that for normal road use the standard manifold is superior to most if not all of the after market offerings out there.
It's relatively efficient, being cast iron it provides superior heat sink properties and so is less likely to blister that lovely picture frame paint that's so close by. I can testify to this, having swapped my GT6 standard manifold for a tubular stainless equivalent some years back. The under bonnet heat was tremendous and on one journey I ended up having to drive in my bare feet!
There have also been issues with flat spots in the rev range with some stainless manifolds.
Personally I prefer the look of the standard manifold especially when it's painted with high temperature gloss black or enamel.

"when it's painted with high temperature gloss black or enamel."

Where did you source a high temperature gloss black paint?

Geoff

Barbeque paint is reckoned to be the best paint for longevity. My manifolds need repainting since the high temperature paint I used wasn't high enough!
I've now bought gloss black that is rated to 1200 degrees C, but this job is on my winter to do list. One good thing though, the old paint has burned off completely so no need to blast the manifolds again.
I'm not staying at my home address at the moment so can't for the life of me remember what make of paint I've bought. I'll check next week and let you know.

I'm interested in Gloss black as well!

I run an earlier offering of theirs, virtually the same design but with integrated connector pipe (flex section) on my S1 4.2. I had mine coated with a high temp ceramic (bright silver finish) before installation and have had no issues with heat at all during 18 years and 20k+ miles.

Stainless manifolds, left uncoated, will discolor fairly rapidly, and any oil or other contaminants on the surface will leave darker discoloration spots/marks that are serious work to polish out, hence the reason I have them coated. Done this on two Elans, the E type, and my Morgan.

Anytime you install modifications that can increase airflow through the engine, you of course need to adjust/modify the air/fuel ratio to ensure it's in the proper range of course which will ensure your exhaust temps are in a reasonable range.

Alan, thanks for the answer but I was interested in the source of the gloss black paint you used, i.e. the name of the paint and the distributor's name. Geoff.

Sorry Gents

I seem to have falsely raised expectations. I did a quick trawl of the interweb and it's suggesting that the temperature should read 1200 degrees F not C. Still capable of handling the E-Type's manifold temperatures in standard tune though.
I won't be home until Wednesday so will report back on the maker then.

Thank you all very much for the insights. I will stick with the originals.
