Best exhaust manifold?

[A&P]

Hi guys I would like to get some feedback/opinions on what the best exhaust manifold is for a williams i.e . flowed std, supersprint, ktec etc..... any ideas? always find it best to ask people who have used them. Cheers ANDREW.

Supersprint/Ktec give good results but can have a tendancy to crack.

will only crack if not braced as per the standard manifold. When they are braced they are fine.

Can you use the standard OE brace with it ?

No but as Northy ill tell you what you can do is make one up. the Supercrack has a couple of sliding plates that line up when you have the manifold and downpipe lined up, you then secure them with a bolt. You could make up a brace which you can bot onto the block and mate it up to this to reduce movement.

There is a flex joint at the end of the downpipe:

Mine on Saturday:



Had to remove it again as it has a tendency to blow on my manifold to d/p joint. Sorted now (touch wood) with firegum paste.

You can get a Devil manifold. Has a more OE style flex gasket I think.

you can make a bracket that utalizes the standard mount - thats what i did with mine A GOOD 5 years ago and its fine!

Is anyone running a Devil? Been tempted to get one since my original started blowing, but can't find much info on them
