3" Dynomax Ultraflow Carnage

I put a 2.25" UltraFlo muffler on my Jeep to quiet it down from the mid-length (22" ??) Classic Chambered PowerStick I had on it previously, been about 3 years and at least 10k miles now with no problem but that's on a 4.0L inline-6 with barely 200 HP. I do love the balance between on-throttle sound and off-throttle quiet-ness but will be much more careful if I ever decide to get more to put on another vehicle, at the very least I will definitely keep the receipt and warranty info. I kind of want to put a PowerStick back on the Jeep because those 4.0s sound pretty cool with open exhaust but it would be the longest one for sure, I have a pair of the long 2.5" PowerSticks on my Duster and they are magnificent at WOT without much drone at cruise and the idle is very pronounced, you can hear the exhaust pulses from each cylinder it's super cool.
