Does anyone know on how similar/different the redtop XE 16v exhaust manifold spacings/sizes are compared to a1.6 twincam vauxhall (i'm presuming he means ecotec.)
1.6 is a different spacing I'm afraid.
2.0 XE and 2.0 Ecotec are the same spacing but different fitting.
Bummer

do you have a std xe manifold?

keep it if you can, chop the pipes off at the flange, clean it up and weld new pipework to it. it is of a solid thickness and is low grade stainless so saves you about £30 on a new flange!
