Had a bit of a leak after I left the shop. Took it back to the shop and they initially thought it was the clamps between the cats and headers that was causing the noise. There was clearly a leak on the passenger side (black soot evident at the slots on the tubing). They said everything in the kit was great except for those clamps at that specific spot. Popped the clamps off and welded it up instead. Started her up, noise is still there... as I suspected, the passenger side header bolts were loose - but to their surprise, not as loose as they thought they would be. The tightened down both sides and it seems like the issue has subsided. I say seems like because I almost feel that I can still hear some of the noise and BARELY smell raw exhaust, but it's hard to say. If it gets bad again, I am taking it back and having locking bolts installed.
For the cold startup video below... the tone is accurate, but the recording lacks the bass that is present. You can hear vibrations if you listen closely... it's that powerful. Once I took those few steps closer, I literally felt the exhaust vibrating my pants. When I was sitting in the waiting room at the dealership today while they checked out a potential leak, I heard it inside the bay every time they started it up, haha. It is much more aggressive than a HC/392 startup decibel wise(if you've heard one), but the tone between the two exhausts is actually very close (on startup only). So again, I cannot reiterate how good the current exhaust system is on the 392's/HC's. Hopefully SRT brings it to the Jeep for the next models.
My fuel level has tanked the last 2 days. I get into the throttle a lot harder. The grin is unavoidable. Once you hit 2.5K RPM, the exhaust comes alive in a way I have NEVER heard from another vehicle in my neck of the woods. It is truly awesome. The difference these headers make combined with the catback is just flat out incredible. aFe's video, while short, is spot on with how awesome the exhaust sounds.
Quick revving and acceleration shot with downshifts and acceleration on the way back. You can hear me on the way back at about 1:25, roughly a 1/4 mile away (have to turn up the volume a bit).
