i know they kinda act as mufflers by quieting the exhaust down but will they cure the dreaded rasp of a catback?

Like many things, it all depends.

If it has tubular manifolds, it could be loud.

My cast iron manifolds (heavier than stock) give my Magnaflow muffler (which is pretty nasty) a quieter note than a stock car. Even without a muffler its not as loud as a stock Magnaflow catback.

In general, a turbo (or turbos) will quiet the exhaust. How much depends on the system.

I hated the rasp sound I had with my old setup but now with the turbo no rasp at all!

All depends on the size of the turbine.

The T3/T4's will quiet the exhaust down a good bit. The turbines are small.
