However, it actually made no difference at all !!
Worth getting this done by someone else with the proper stuff. The stuff inside will be seriously carciogenic/toxic, not to mention the mess it makes. Just not worth the hassle.
The EGR on the other hand....... ! Well worth doing.

I am sure it must have made a difference i know how i would like my manifold to be inside, don't forget some of the manifolds can be really bad which in turn make the engine bore close up as below this was a members manifold i changed for them
