Fleabay cat back muffler?

[DWBOX2000]

I would love to hear a really bad drone. I have a beluga on mine and I think it drones a bit between 2700 and 3000. It's really not bad and I just think of it as the car saying "Let's dance". I am just curious if what is not bad to me is bad to others.

For me I found that it reverberated at frequency that felt like it was vibrating my head. It just made my head sore. It's a really cheap system that obviously wasn't acoustically engineered lol. I mean just look at the thing.

I think a lot of the drone was due to the fact the one of my clamps between the cat and C pipe is past it's prime. I tightened it as much as I could with a 3/8 ratchet. The drone at this point was unreal. It truly sounded like a 120 decibel pipe organ playing around 50hz was behind my head. That was with the top down, up it was even louder. Since I torqued the heck out of the clamp with a 2 foot breaker bar it's much quieter now. I'm sure I could tighten it even more, but i'm scared the bolts will break.
Either way once it gets out of the drone zone it sounds awesome. I will put the new clamps on when they arrive. If that doesn't get rid of it i'll try the baffles.

OK new clamps came on Friday, so I installed them. While I had the C pipes off, I tried a baffle. On the passenger side I cut the end off one of the baffles and put it in the C pipe closest to the muffler. This cut the drone down about 75%. Today I put the other baffle in the drivers side C pipe. On this side I used the entire baffle wrapped with hi temp fiberglass. This is the way it came from Car Chemistry. This set up dropped the drone to about 99% gone. It might be too quiet now. I may open the passenger side back up and take another inch or two off that baffle. The way it is now it is basically sounding like the stock system with a crios mod at idle. WOT it is a little louder and deeper. On over run I can hear some burbles. I'll roll with it for a few weeks before i mess with it.
