Wrapping the exhaust also depends were you live. Humidity or rain does soak the exhaust wrap with water and even if it evaporates real quick it will accelerate corrosion if stainless isn't used in the dump pipe.
High combustion temps behind the turbo keep up the speed of the exhaust gasses resulting in a better scavenging effect. Resulting in lower backpressure and better turbo spool-up. In front of the turbo it definetly keeps up speed and lowers underhood temperatures drastically.
Is it measurable? In a stock engine? Barely not. Overall losses are to high than to expect any gains. But the overall mods will sum up.
I wrapped mine and I did it to lower underhood temperatures and to release the intake from the radiant heat. Performance gains? Not really caused by the heat wrap...
Wrapping is more a gasser thing because effi is a lot less and heat in the exhaust rises up.
The advantage of a ball bearing turbocharger will have way more effect than an ordinary wrap- or different expressed: a wrap won't turn the performance of your ordinary turbo into a ball bearing unit...
Wrapping the intake? Hell no, just make sure you get fresh ambient air from the outside. That means no open air filter. BHAF with a sealed box and large openings to the outside to ensure fresh , cool air supply.
Wrapping the exducer housing? Seriously not!
