Magnaflow cat-back system

Does anyone have any first hand information regarding whether there is a drone issue with an LT1 w/Magnaflow cat-back system?

Just one opinion, but when my "flows" were installed, I was disappointed that the exhaust note was not much different than the stock mufflers.

Over time, the exhaust sound gradually increased, and about 6 weeks into the new system, the drone was uncomfortable in the cab.

I installed the Flowmaster Force II Cat Back system and I love it. No drone. Sounds great on the outside. No drone from idle to 120. Awesome.

I have a magnaflow catback on my car (unsure of model). Engine noise is a dull growl and very easy to live with.
