The previous owner of my Alpha removed the muffler leaving just a resonator. Sounded great, but droned bad in the backseat. Removed resonator and installed a magnaflow and it now sounds great with no more drone.

I had mine done the same way. I've got a hole in my resonator and my 2nd cat smells horrible when I get on it so I'm thinking about removing them both and putting in a cherry bomb or something. I've already gutted the exhaust manifold cat and discovered I've got 2 broken exhaust manifold bolts in the back in the process, so I'll have to do something about that soon as well.

Sounds fine on the 5.3L V8 with the OEM muffler removed, and resonator replaced with a magnaflow. Inline engines just don't compare when it comes to sound output.

I think think it sounds horrible, just my opinion. Why would you want a Hummer to resemble a honda?

I get where you're coming from but the video doesn't pick up all the sound and deepness trust me it sounds nothing like a riced up Honda. Maybe it's just me cause I just switched from a mustang after I totaled it and it had a loud exhaust and I like cars sounding loud

Well its loud.. just not nice (opinion)... invest in a Borla catback for a better sounding exhaust... They're selling really cheap since Hummer was discontinued.
It wont be as loud and noisy, but at least it'll sound like a decent truck.

And its a Hummer, not a Mustang... So.. yea..

Also, i think you're getting rid of too much back pressure with this setup. Not a very good thing performance-wise.
