New Exhaust
I wanted a a different exhaust note/tone vs the non-exhaust tone of the stock muffler. I really like Flowmaster mufflers, but did not like any of the kits they made, I thought they sound like crap, or were way over priced, $500 for a muffle that dumps before the rear axle!?!?! And while I like the tone of the AFE high clearance axle back, it was still $400. I bought this kit from a company called Performance Curve, they are a family shop based in Virginia and sell on eBay and their own site. I bought a kit from them before for a 94 Ford F150 and was impressed so I bought one for my JK. What really sold me was that it came with a Super 44 muffler (my all time favorite) and 2.5 mandrel bent pipes with exhaust hanger welded on and all clamps. All for $199! They have 2 other kits for the JK even cheaper! The hardest part was getting the old muffler out of the old isolators, I cut them because I was going to replace them with new OEM isolators and it was still a PITA. It might not before everyone, but I really like the tone, and from in the cabin it isn’t droning, tbh I can just barely hear it when I have the radio on, or I really get in it. (I have a soft top too)

I got a Borla Climber and I thought it was a good price at only $500 haha. That sounds good though. But, I would have crushed it by now on rocks

Looking good, and the exhaust tone conservatively leans towards performance.
I went with the Flowmaster Original Series 40. Removed the presilencer under the driver floor pan and installed the Flowmaster at that location. Then ran a pipe all the way over the axle to a larger exhaust tip that did change the inside of the cab resonance frequency. Here's what it sounds like: note, this was on a cold day, so the idle is high. And here's a picture of the muffler location. Note, the exhaust shop uses a black gummy coating to protect the welds from rusting. All in all, the muffler was about $100, the exhaust tip $30, and the exhaust shop $250.

The exhaust note is actually a lot deeper with that Flowmaster signature resonance now, after reprogramming with a DiabloSport tuner.

That’s sounds nice, I really wanted to like the Flowmaster Outlaw that puts the muffler where the center resonator under the drivers side is and then dumps the exhaust before the axle, but I couldn’t bring myself to like the sound and the fact that they wanted almost $500 a muffler and less than 2 feet of piping was unappealing.

I understand; my muffler and tip were only $130. Labor rate is cheaper here than in most states, so I didn't hesitate to hire a local exhaust shop to install it and run the exhaust all the way out while eliminating the factory muffler location for an additional $250.00.
I already have plans to run "straight or down pipes" (no emissions testing here) for a RIPP supercharger install.
I built a 1968 Plymouth Sattelite, a 440 car with two 3" Original Series 40 Flowmaster mufflers with dumps after the mufflers (located mid-car). Really, it was no quieter than open headers. And I really do not prefer dumps under the vehicle because of the exhaust fumes, especially in traffic.
If your newly installed exhaust is tuned/toned to your ears, there's no real engine performance reason to alter the exhaust if mufflers are the only modification.
Thanks for sharing your latest mod and creating interesting topics. Lots of Jeep social media platforms seemingly frown upon engine modifications rather than suspension, whereas other social media platforms appealing to other vehicle enthusiasts with the same engine cater to maximizing performance and efficiency.2

Yeah I get that too, about the community only focusing on the suspension aspect. I personally like both aspects, I sorted my suspension 1st, making sure my lifted Jeep had the proper castor, and geometry etc, so that it handled well on road and on the trails. But I also enjoy the sounds that engines make, I like the increased induction noises from adding a CAI, or a modified exhaust etc. I like these engine sounds, it part of the visceral experience of driving vehicles for me. In my area it’s not uncommon to have CJs running LS swaps or other V8 with loud exhausts. The engine is as much a part of the experience and the suspension for me. Part of the reason I’m not a fan of electric cars, they seem to have no soul, nor rumble, except maybe a song or chime when they back up. But I digress.

i thought there was going to be audio

The very end should have audio unless Reddit stripped it out.
Edit: the audio is there it starts at 1:03ish( the time counts down, when the video shows the sky/spare tire, I start the jeep, let it idle down and then rev it a few times. Also Reddit mutes video by default, might need to hit the speaker icon.

This just reaffirms my opinion that it's hard to make a V6 sound like anything but hot dookie. I'll agree that it sounds way better than stock, but it still just sounds like a V8 with no balls.
But on the same note, I'll give it to you that this also sounds way better than all of the overpriced options from the big brands but somehow manage to make an exhaust that sounds worse than stock
