Only wrapping the from the cat back will not produce as much power compared
to wrapping the header along with the piping. A significant amount of heat
or energy loss occurs at the exhaust manifold or header. it makes sense to
insulate the heat from the beginning and continue to do so. other
considerations would be the cost and weight of the wrap. Will the power
added offset the amount of weight added to the car?, or, could you make
power somewhere else for the same amount of $. How about dynoing the car
before and after the wrap? That way, we could all know if it is worth it.
Let us know. Good luck.
