My stock muffler on my 2003 WJ 4.0L has shifted. Now the tail pipe is rattling against the gas tank heat shield at idle (resonates at idle). To fix the problem, I'm using it as an excuse to upgrade.
After listening to a ton of youtube clips, I like the Magnaflow mufflers. I would have it dumped after the muffler and avoid any tail pipe. I specifically like this one from videos:
Does anyone have this muffler (or any Magnaflow)? I'm wondering how loud it is under normal throttle? WOT? Does it drone? Or anything else.
