Your shop is correct, Reducing exhaust back pressure raises the ceiling of power on the limited Octane at the pump.
Out of the entire exhaust, the manifolds and cats are the most restrictive.
The cat back is not as bad as it looks but there is something to be gained there.
Think of the exhaust like this, it is only as good as the smallest hole which is up front.

Thanks man. That will keep me straight. Was definitely looking to see about what would give me the best bang for the buck right now so it looks like headers and high flow cats.
Thanks again
