Took the Gruppe S headers off the car at the weekend to cure a small leak where they bolt onto the block.

Noticed when seperating the headers from the up-pipe there was about a third of an inch gap bewteen the two and also the headers to up pipe gasket was the wrong size (standard gasket).
Think it was 2 inch in diameter, but the bore of the headers and up-pipe is 2.5?

Decided to make a gasket from some stuff I got from C+C Exhausts in Hillington, which is quite thick and looks like an old floor tile
Sealed well, but has started to blow today between the headers an up-pipe so looking to get some good gaskets.

Anyone got any recommendations please on where to get some?

Found these, Gruppe-S funily enough



These are similar to the OEM gaskets, but are beefed up to 5-ply instead of 3-ply at our request (Downpipe gasket is composite).

-Manifold to engine (x2)
-Manifold to uppipe
-Uppipe to Turbo
-Turbo to downpipe
-Downpipe to Exhaust (3")

The material you mention is no use at all with the manifold to up-pipe connection, there's too much heat and the material goes brittle very quickly and breaks up.
It's fine for joints after the downpipe though, as there is less heat there.

Cheers Alan,

Will take it easy then until new gaskets arrive

Have you got the wrong original gasket then?

Scoty

Yeh it's the wrong one mate.
The rest of the gaskets are OK realy, apart from the downpipe to centre section, which was also made from the floor tile stuff.
