Yes, you want to keep to turbo and the exhaust pipes hot as you will lose
velocity in the moving exhaust gas as it cools. Remember hot air is big and
will shrink as it cools (not the thing you want when using exhaust pressure
spin a turbo) A trick it to use header wrap on the housing and pipes this will
reduce the temps out side the wrap while keeping the exhaust gas hot.
I have used this wrap many times in auto applications and it is amazing how
much heat it reflects back in to the exhaust. On one Honda civic B16 conversion
I did the header is 1/2 inch from the radiator fan and after wrapping the
header you can touch it without burning your hand. Tip soak the wrap first
before
you wrap your pipes it conforms much better wet.
Then hose clamp the ends and soak with hi temp paint and you will have a nice
insulated pipe that will hold up to the elements better.
