ACT Stainless Exhaust Manifolds
Discussion
Hi Cerbera fans
My standard manifolds are cracked and I like shiny things on my Cerb.
I have talked to Tim over the phone about my options as I see he does 2 different set ups for the Cerb. I was going to use my Local chap who made the rest of the exhaust system, it will be a right faf about as I would not be able to get the car to him as I am removing engine and box in the new year to do a few jobs. So of the shelf seems around the same price and less hassle for me.
Can any one who has either the 3 piece set or 1 piece comment on there thoughts about the pro's cons or any other general comments on these manifolds . I am swaying toward the one piece units as i thinks its all i will need on my 4.2.
Over to you guys

I have the performance version, is that the 3 piece I am not sure.
No cons that I have found, they have been on the car about 2 years with no problems at all.
Pro's are more torque and it seems BHP but I did put the whole large bore sports system with Decats at the same time but as a package it is very very good if somewhat loud.

I had the three piece on mine. I was quoted 8 hours to fit them but I managed to have a mechanic I knew (non TVR indy) fit them for 4 hours at mates rates. He said it was a b
h of a job and I did need to make some brackets up to stop the exhausts touching the bellhousing.
The benefits are;
1) can be fitted easier as engine does not need tilted
2) easier (quicker) to remove as they are modular
Downsides
1) correct silicon sealant MUST be used and allowed to cure. Failure to do this WILL kill the Lambdas and result in air leaks
Fortunately Tim's aftersales was faultless and he helped me get them all sorted as a goodwill gesture.

I was advised away from the 3 piece by an indy I trust, unless you're going for ultimate HP, the OEM design is pretty good. Difficulty of sealing and remaining sealed being primary concern.

STR8SIX have had gaskets made to fit the exhausts so no need for silicon.

I can honestly say that this has not been a problem for me.

If thats old news or the design has evolved, then happy to stand corrected.STR8SIX have had gaskets made to fit the exhausts so no need for silicon.
I've had them on mime for a while too - the earlier version - and my only real gripe is that its almost impossible to completely seal the joints where the sections bolt together. This isn't the manifold to head joint - its where they have used only two bolts to secure the sections together. Perhaps the new ones have a 3 bolt setup?

Cheers guys i think the ported standard unit will suit my needs just fine and should be easy enough to fit with the engine out. What do you use a gasket for the manifolds just a sealant or can you get a gasket?
I sourced 4.5 manifolds and had them Zircotec coated. i think they turned out rather nice.http://www.youtube.com/watch?v=sUxupbtPoEI&fea...
