I missed your post earlier but I have the Hooker Blackheart cat back system with mufflers and I think it sounds great! I would imagine the non muffler system would be pretty loud considering how loud the Billy Boat Bullet and straight pipe setups are, so if you want "a bit more aggressive exhaust note" I would recommend the muffler system.

The marketing copy says "deep muscle car tone" which I'd definitely agree with. What I like about it is I find the LS to have a weird sound than other V8s (I think it's the firing order) but this has a deepness and spacing between the pulses that seems to fix that to my ears. It has straight through muffler sound, not the more hollow metalic sound like a Flowmaster and some other chambered mufflers. It's the best of both worlds in that it has a deep tone at idle and low RPM, gets a nice higher pitched growl as the RPMs go up, but it doesn't drone, it doesn't get progressively louder or harsher, the pitch just changes, so you feel like you can have fun without ruining everyone's day or your ears, can still easily talk to a passenger, or listen to the stereo.
I have a couple videos which aren't that great, but give you an idea.

Urban driving so I don't get on it too hard, but at 1:40 I cruise at 60 km/h in 5th, 4th, and 3rd gear, at 3:00 I get on it a little bit more, at 3:40 I roll down the windows for downshifts, and finally at 5:10 I get on it a little bit more again.
