What Is That? Info/Link/Etc/Where To Buy,Please?! 

FYI, exhaust piping also can b use TSD boron nitrate, but kind a waste. normally ppl spray it on radiator, condenser, oil cooler, interco0ler, etc. those thing need to reduce heat fast.

due to the price u can get for this TSD boron nitrate, that's too costly.
price for u guys to reference that i found on a forum for this TSD boron nitrate: $155 per 250ml bottle, 10 bottles at $150 each , buy 10 free 1

*price is on SGD

about the link u gave above they got stated about the place to apply this TDS boron as below :

"1. Automotive - radiator, air cond condensor, gear box housing, turbo, intake manifold, engine cover, exhaust, oil cooler, oil pan, ATF cooler, brake calipers, brake pads and battery"

is it recommended to spray on exhaust piping or manifold or not ..this i'm not sure.  for what i learn, what i know, the correct degree for both intake or exhaust valve overlap, with the nice exhaust system setup, the exhaust piping inner surface, etc. this all will help the exhaust gas flow smoother...

n really never heard about hot exhaust gas will flow more smoother than cooler exhaust gas, this i will try to search n c any info on this or not...

from theory ...exhaust gas might same as intake air, if the ex. gas was cool mean higher density, can b increasing the amount of ex.gas to flow out to the exhaust system, mean exhaust gas can flow out more faster than when ex. gas was hot, agree ? if wrong pls correct . keep discuss on this, quite interested to know about this 

for my point of view, ceramic coat or thermal wrapping to contain the head inside is bcos to avoid the heat to affected the intake air temperature.  expelling heat will increase the engine bay temperature, i'm agree on this, but just for when the car is stop there n not moving.
cos if i spray on the radiator or condenser...it help to expelling the heat also, even i'm not spray it on the extractor,  once the radiator fan working...all the heat will suck into the engine bay also, engine bay temperature will increase also.

hv another way to do on the thermal wrap, that i found out on those custom chopper builder, take the thermal wrap to do ceramic coating. but this kind a costly move also hehehe

if any1 hv more information on this, pls share it here n discuss together. thanks 

ok bro, found some data on the net for ceramic coat as below:

"Ceramic coatings have proven themselves in engine horsepower gain by reducing friction, heat, and wear. The most common applications for ceramic coatings are on the exhaust system, manifolds, and headers. When ceramic thermal barrier coatings are applied to exhaust manifolds or headers, they provide two advantages. They protect the headers from rust and corrosion and also reduce heat loss(means the heat will transfer equally to the whole parts & radiated heat temp. will reduce), which translates into high power output. If the headers are internally coated, they will create a higher velocity of the hot exhaust gases and less turbulence due to a smoother surface."

n thermal wrap was just reducing the radiated heat temp. it won't help on the exhaust gas flow rate.

1 more thing, since u mention that engine bay temp can b increase. yup it can b increase, no doubt, but y we must keep mention about the keep the engine bay temperature down, cos this engine bay temp might affected ur intake air temp (some of the ppl using others weak heat insulator air ram, this might hv posibility increase the intake air temp. also. I never say that intake air was from the engine bay, some mightb cos of using open pod air filter), engine surface temp (that it might hv posibility transfer the heat into), etc, of cos affected the engine performance also.

its as important as reducing the engine temperature. lower engine temp. can b extended life of others component that surrounding the engine, of cos is the same, lower engine temp. can extended the engine parts life also.

hope that no hard feeling ya bro, i do enjoy on this discussion, cos learn a lot. 

yup u r right, but due to modification wise, some of the owner might replace those plastic parts or remove it, n using some unknown material parts, this is an issue.
