Personally, I would still mount it like in my videos, but that is just me. I want to know how much heat has soaked into the devices more-so than what is moving through, simply because with my own tunes, I know that the combustion temps are not being exceeded. Also, turning on the engine fan and watching the external temps drop 100 degrees, cools all the components and extends their life. It is not the fan "fooling you". It allows for higher internal temps. Think about the piston liners as an example .... No water and they will not last 30 seconds,.. but with water on the OUTSIDE of them,.. and they go a million miles.

It is all a balance of heat, and what you do with it to dissipate it. My opinion is -- Who cares what the internal gas temp is as long as you know it is always in spec,.... It is now only a matter of how hot the components are and how much their lifespan will be shortened by their actual metal temps. -- You can put 1600 degrees into the back of your turbo and NOT melt anything,.. but 2 minutes later,.. when that casing gets to 1,000 + degrees and starts to glow red,.. NOW you are in trouble, but not until you have reached that point.

This is just my own personal take on it,.. I have worked with a lot of people who have constant high engine loads on ISX engines in the past.

Personally, I think if your average engine load is above 60% long term on that engine,.. you have undersized the engine for its task,.. and yes,... doing everything you can to extend its life helps,.. but you are facing the fact that you are running it in a manner that dictates a very short lifespan no matter how you look at it.

It is simple physics... The a rough rule of thumb is that the "USE" you place upon a mechanical component,.. The shorter its lifespan,.. and typically, it is proportional to that use. I.E. -- making 50% more strain in one engine all the time compared to another would dictate it only lasts half as long.

Actually,.. if you want to do the best thing for it, and to satisfy your own personal goals, .. Put TWO pyro sensors,.. one in the pipe,.. and one on the manifold. $30 extra bucks for a second sensor and a switch is cheapo insurance. Tell me what you are happier watching going down the road in 6 months from now. -- everyone I have even met that did that,.. prefer the manifold, Even heavy haul guys. Perhaps what you do is the exception? -- so do BOTH,.. and let all of us know in a few months here on this forum what your own preference is, what it does for you to help you, and why. -- That will be the only way for you to answer your own question on here because it is you who you need to satisfy, not anyone else.
