Has anyone had any experience with flowmaster mufflers? If so, what muffler did you use, are you satisfied, and did you notice any increase in performance?

I have the Flowmaster American Thunder Exhaust Kit on my 2008 JKU.
It does get loud... I does Drone.. It did add a little Performance.. And I think most aftermarket mufflers will...
I didn't get it for performance though, I wanted to relocate my muffler and install an Air-Tank (Viair 2.5gal) in its location. For this reason alone I would recommend this type of swap. I'm also not going to show it off until I make some sort of Armor for it (while it doesn't hang as low as the muffler did it still just LOOKS vulnerable)... but that'll be another thread..
I have a flowmaster on my MJ and like it a bunch. The tone is great and makes the 4.0 sound strong. I don't think you're gonna get a noticeable horsepower increase with any aftermarket muffler. To get a small increase you'll need a can the size of a '57 Caddy along with an intake change. Surprisingly the stock goodies do a very good job. Jeep spent lots of time and money on the dyno to maximize HP and not give you a headache on a road trip.:twocents:
I had a flowmaster 50 series installed custom at a local shop. Doesn't have the drone of the old dynomax Evo that I had before. That drove me crazy. Here's a vid I took a couple months ago, it's gotten a bit deeper since. http://youtu.be/YQw4nGbqB2g

I had a flowmaster super 44 on my 2007 JK and loved it..got several compliments on the sound while I had it. I have the dynomax now and I like it pretty well, but I liked the sound at higher RPMs better on the super 44.
I am thinking of going with the dynomax cat back system with tail pipe, anybody use this system yet?
Which one by chance?

I got a Flowmaster Delta40 for free.99 off an old buddy's project. Can't beat free, but I'm going to swap in a Dynomax and tuck it up towards the tub
