Put this on today and took about 2 hours, only because getting the old muffler off was such a pain in the ass.. Got the rusted muffler clamp off with my Dremmel tool, very handy. After that, pretty damn easy. Love the look and the sound..
The only bad thing about this muffler is the angle it sits on in relation to the body. It ends up very close to the sway bar and you have to bend up the heat shield a bit. Sounds good and not too expensive.
