A few months after I paid off my Jeep, my muffler blew up.  I'd been having ignition coil problems, and some (well, probably a lot) unburned fuel must have made it out my exhaust ports.  I was turning into my street with my wife in the passenger seat when there was a huge BANG like a high powered rifle.  Lucky she was strapped in or she might have ripped the soft top off she jumped so hard.  It was so hilarious, she was freaking out.  I could hear my now insanely loud exhaust so I knew what happened, but I just started laughing my fool head off.  I still remember the look on her face.  "What the heck was that?  And what the f*** are you laughing at??!!"  Next day my dad took it to the local redneck [censored] exhaust shop and had them weld on a $20 cherry bomb glasspack with the stock tailpipe.  Love the sound and it pi**es the ricers off when I rev it and drown out their awful exhaust noise.
