Says it won't fit my Jeep on Amazon but that's because it is an aftermarket right? LOL

That will work. The muffler needs to be offset inlet center outlet in 2.5 inch. Thats what amazon lists for that 50 series muffler. Maybe it says it wont fit your Jeep because flowmaster mufflers are about a foot shorter than the oem so when its installed you need a foot section of straight pipe prior to the muffler. Im running the 50 series SUV muffler on my XK. It hard to tell in this picture but this shows the straight pipe in front of the muffler.

Why 2.5"? They make 3" I/O
Well 2.5 is the oem exhaust diameter. If you got a 3 inch it wouldnt just weld right in. You would have to do 3 inch exhaust off the rear of the muffler and have some sort or piece prior to the muffler changing it from 2.5 to 3 inch. They make 3 inch cat back exhaust that bolts right to the oem flange if your looking for 3 inch. But like I said if you just want to cut out the oem muffler and weld in a flowmaster you want 2.5 inch

For some reason I thought the 5.7L is 3", not 2.5". Will have to double check.....
I based it off the Flowmaster application guide:
2005 WK 5.7L 50-series PN 9530560
3" offset in / 3" center out
..... figured they didn't change the exhaust system in following years.
Also all ram truck 5.7L applications in our model years have 3" I/O specs.
Guess there's nothing left to do but get out the tape measure! Lol
