1979 300 replacement exhaust system.

[LS-300]

I'm looking at replacing my exhaust system. The car is a 79 300 with the 360 4bbl in it. Currently looking at the Magnaflow 19303 system and also getting the headpipe to the system pipes as well. Anyone used this system? How loud is it and how difficult to install was it?
Is they any other complete systems out there that don't drone or are extremely loud that can be installed DIY?

I'd used their dual headpipes, and custom-fabbed the rest of the system myself. But the headpipes are a great fit ! I'd imagine that system should be just as well.
