My S109 has developed a leak around the exhaust manifold. It looks like some type of silicone sealant was applied to it before. The mating flange to the exhaust pipe also has one of the corners cracked off so I am replacing the manifold.

I have purchased the manifold, fixing kit and gasket to replace the manifold. Is there anything else I should pickup prior to starting work?

I will review the manual but would it help to remove the drivers side fender to get easier access to the manifold?
