Thanks buddy, I installed finally the Magnaflow and it sounds very nice (not a 392 tough lol), hopefully they made a good work, the place where I bring usually my jeep is very reliable and the guys are really professional...finger crossed!!!I put one on my JL before taking delivery of it and it sounded decent but now the whole muffler body is rusted and corroded. The dealership installed it but they are crooks and I refuse to let them touch my Jeep any Ionger (River Oaks in Houston, TX). The ship who now services my rig said they reached out to MF in October and they said it would be 2 weeks before they were shipping product again and that they would send a new exhaust out. That was over a month ago and they have not heard anything.
So if you are looking for something with a decent warranty and customer service I would go another route.
