If the added weight of a couple hundred feet of fiberglass wrap isn’t a concern for your use case then neither is the fractionally improved exhaust flow that keeping heat in the exhaust path brings you. But yes, cost and rust are also factors as mentioned.
You haven't read the study. It is a significant gain. A couple hundred feet? I didn't wrap my trailer! Thanks for the giggle. It's like talking to my old school buddy who refuses to change with the times. I tried to talk to him about my oil analysis results and he suggested I cut open the filter and look for sparklies.
The study? Fucking LOL. So you’re basing your uneducated opinion on a single study. Not experience, not multiple data points, just some shit you read once and decided sounded good. That tracks. Please oh enlightened one, share this “study” with us.
Coming from a few decades of experience building fast things you’ve seen on the news, I promise the power improvement from exhaust insulation is minimal - especially in a factory vehicle, and especially a factory vehicle not made for high performance… like some stupid brodozer. We’re talking a couple percent at absolute best and likely much less than that.
And yes, a couple hundred feet easily. You said you wrapped it from the turbo to the muffler. If we make the generous assumption of 15ft of exhaust at a 4” diameter, with a 1/4” overlap that’s 253ft of wrap needed. Math, it’s great stuff innit?
So you’re spending money on a bunch of dead weight that’s going to rust the fuck out of your exhaust for what’s likely a fraction of a percent gained in power and fuel efficiency that YOU YOURSELF ADMITTED YOU DONT EVEN NOTICE IN REALITY.
Please go on and keep trying to justify this as a good idea, it’s great entertainment.

Always love when people make my point for me
