Ok thanks .... I like the sound of mine too ... Just hope it survives Moab in May and my local rock climbing ventures

Mine is a 2011 too, I swear they sound better than 07-10 3.8's because 11's only have one cat per bank. Mine sounds deeper compared to others on youtube. I think thats the difference.

Look forward to the update(s) and I want a sound clip of a super charger and an UFW.

No. Im running it with the mbrp off road exhaust on my 4 door. Had to get a bend made to fit the offset muffler. If you have a 07-09 ( and some 10's ) with 2 cats per side, your ok to cut the bottom ones out. Just dont expect much for gains, just noise. These 3.8's dont sound the greatest.

I have a 2012 and installed a AFE 2.5 inch cat back hi tuck with the 22" muffler option. It sounded bad ass. 6 months later i wanted to soften the sound for a long trip and I added a vibrant ultra quiet resonator after the muffler and it has a nice deep tone with 25% less volume, no drone.
