Hi Jura.
i knew this would get taken the wrong way, not converting any turbo nor the headers
standard style and position headers and turbo
UP-PIPE for single scroll but splits in to two pipes in the middle flanges are the same.
something like this a few people do them simms and so on ment to be good eg flow

Not sure about this Up pipe,but single will have still better flow than two,maybe someone will disagree and prove i'm wrong,but not sure

thanks for some input Harvey, bought a full set of headers and up-pipe from you before a couple of years back as was very impressed.
was just interested in comments and info on these from anyone who had one fitted? i believe simms do them and a few people run them, and maybe japspeed do one?
as for performance i also would think splitting the flow would decrease performance but i am no expert lol, but if these is no benefit at all and only a performance drop then why are people selling them lol, i know thats not a good example but you know what i mean.

The purpose of ceramic coating is to act as a heat barrier, just like exhaust wrap. Its purpoe is to keep heat (or cold in) or heat (or cold) out. Thermal barrier. Turbo exhaust housings are a good example.
Never ceramic coat and then heat wrap on top. Heat retention is to much and the flaking of the ceramic coat will take place much sooner. On some surfaces, particularly stainless steel, ceramic coating will flake in time with the continual heat cycling expansion and contraction.
About 7 years ago before ceramic coating became a must have item I went on to ceramic coating for a period of about 18mths/2 years and then reverted to heat wrapping and DEI in particular. Similar thermal retention, far cheaper, more cost effective and done properly, just as durable.
