Looking for some advice as usual.
After getting bored of welding up my manifold every year for the last two years, I have now decided to have a new one, trouble is which one? The options are obvious, 1 mild steel system, 2 stainless steel system or 3 mild system ceramic coated.
The mild steel option is obviously the cheapest, and I believe (please correct me if I am wrong) heat build up is slower and heat transfer is quicker, therefore reducing overall heat production (particular useful near rubber engine mounts!) and exspansion, however there are the obvious issues with corroision, presumably resulting in the low guarentee period.
I think I am correct when I say the stainless item will be better in relation to corroision issues, however I also believe stainless disipates heat less quickly (remember those engine mounts) and is more likely to crack as it has a higher rate of expansion. Not ideal when we are fully aware of the 2000/2200 tc s reputation for doing just this. With this in mind however, contrary to what I have just written, strangely enough the stainless items do seem to come with a lifetime guarentee, suggesting no problems at all with continued longetivity.
If my understanding is correct, internal and external ceramic coating purport to retaining the advantages of better heat dispersion/exspansion as regards mild steel whilst also delivering the corroision resistance of stainless. However from the limited research I have done this advantage only lasts as long as the coating, the time limit of which seems very varied and difficult to pin down, between different ceramic coaters/processes.
Its all turning into a bit of a quandry so I really would appreciate any advice that would help solve this particular dilemma.
Thanks in advance for your comments.
