Oh, well you didn't specify! 
OK, I have had both on my car. I had the Flowmaster Force II system and the muffler seemed very quiet. Too quiet. PLus, it still had that famous Flowmaster sound, which to my ears is rather tinny sounding.
I have the Hooker Aerochamber now and to my ears it is deeper in frequency, does not sound tinny and has a much more pleasing tone to it.

Force 2 huh?? Maybe if u compared like, the 80 or 40 series to Hookers' best muffler, the results might be different. I have heard that some Flowmasters have had a hollow type sound instead of powerfull. I'm trying to find out which 1's those are, so I don't get them, and if there are better sounding mufflers. I want a very powerfull and very loud 1, with lots of exterior and interior resonance!! Dual Tailpipes too!!

You want hooker then. That exhaust is SSSOOO nice. I would get it but my friend with his 89 Iroc-Z has it already. Besides the fact that the 3" Aerochamber looks pimp as **** with the dual pipes coming out the rear, he doesnt have a cat tho, but neway, I luv dat god damn sound.

I also got a hooker aerochamber catback system, and it sounds really deep and mean. I don't have a cat either.

I have the Hooker Aerochamber as well. I also have a catylitic converter, and my L69 is now running nearly 100 MPH in the quarter mile.
