The temperature at which Aluminum melts is 1220° F. The exhaust manifold could easily reach 800° F. Further down the line where most mufflers are located, is between 100-300° F. Aluminum would definitely stand up to those temperatures, however the challenge is going to be attempting to weld Aluminum, to mild or stainless steel because they two metals don't mesh. There are different methods which make this union possible, but they are not something a hobbyist should attempt, seek professional advice on that one. I would suggest using an exhaust cut out instead.
Answerif this is on a 2stroke the governors are on the throttle handle and the exhaust take the exhaust off at the head and there should be a washer in the exhaust remove the washer. on the throttle there is a screw that stops the throttle from going full throttle remove that screw. there usually by the throttle & to take out just a few screws
located right of the exhaust manifold and connected to the throttle linkage.
The Cobra's exhaust is made in the USA and is backed by a lifetime warranty. Their exhaust pipes are made to withstand any type of force you can bring to it.
The motor chokes at full throttle because either the exhaust valves are bad and cause the motor to loose compression at full throttle or the carb has an air leak.
don't remove the throttle body. just the exhaust pipe, the air inlet tube and the heat shield.

Yes and no. Rotary exhaust is normally between 1800F and 2000F. Exhaust components that are not made of thick wall steel will not be able to withstand the heat cycles. Also if you are reading higher than normal EGT temperatures this can mean your engine is out of tune.
Increased driving noise under throttle can be indicative of an exhaust or intake leak. An exhaust leak can also give the symptoms of loss of power under throttle. At worse this could be an internal engine issue, and continued driving on the condition risks further damage.

behind the throttle body...it looks like a motor facing downward toward the exhaust manifold. it connects the tube from the exhaust to the lower intake.
The EGR ( exhaust gas recirculation ) valve is located behind the throttle body on the passenger side.
Too Lean. Bump up fuel pressure.
