Time for another major job on my list, the exhaust manifolds. The work has started with the removal of the original manifolds. there were several issues with these. The first was back pressure which limited the power output possible, The second was durability (they were thin gauge and prone to cracking) third issue was installation and removal of the manifolds. In fact without removing the heads the only way to get them out is to cut them, at least, on one side. So first order is more power, second order is for more durability. third an improvement in looks and, lastly, simplify installation and removal. Sorry, there was one other issue. They were extremely ugly.
Also wanted to remove the ‘notch’ from the outlet, which we did.
The company doing the work is Elweld Fabrications. Elliot is ex pro drive and been involved with car preparation for most types of motorsport including WEC,WRC, and F1.
As an aside several other mods are visible in the first photo; Denso coils, aluminium spacer for the original plug cover to fit over. Blanking plate for the air idle thingy that’s been removed.
Elliot has produced an absolute work of art.
