Where the exhaust tube connects to the bottom of the manifold there is 2 seals. on the old one they seals ore tight around the exhuast. If anyone know what i am talking about do i need to heat these to the the exhuast or can i just put it together?

 

The two little donut seals? They are meant to slide over the collector pipes and then crush when you tighten the flange nuts up.

 

Yup thats all i needed to know, thanks thats perfect
