Maddening, eh? Same happened to me... but I bought one when they first came out. I suspect the one you received was new old stock (i.e. first run like mine). I would contact Magnaflow directly and complain. They make great mufflers... but the lack of QC is unacceptable.Ordered a Magnaflow from Northridge on 7/ 11 for a 2019 JLU sport. It said it was on back order and would ship direct from factory in about 30 days. Northridge did have the $250 gift card promo available and I received it. Got the muffler yesterday 8/6. Doesn't fit. The pipe that slips over the factory pipe is too small in diameter. I had read that this was a problem last year but they had fixed it. Nope. Spent 2 hours trying to install. Broke my pipe expander trying to get it to work. Ran out of time and had to put stock exhaust back on so my son could use the jeep while his car's in shop. Not sure if I'll take to muffler shop to get it expanded or just send it back. Wasn't happy wasting my time on something that was supposed to be a easy install. Will post update when I get Jeep back and decide what I'm doing.
