Just did this, and I didn't even bother to jack up the car or remove the front wheel. Just crank the wheel full to the left and you'll have enough room to get everything out. FYI, get a stubby phillips screwdriver, as a long one will be difficult to get at the correct angle, especially if your car is low to the ground. The toughest part for me was getting my head under the front bumper to find that PITA 3rd bolt at the front. Once you find it, though, just keep on turning till it comes out.
The hardest part was getting the unbolted resonator out of the wheel well - it was like the car was giving birth - Messy but everything came out in the end... lol
The sound is noticeably nicer now, more bottom end tone but only when accelerating around 2000-2800 rpm. Higher than that it seems to be the same, which is good for general driving around. I recommend this as a great FREE mod you can do in half an hour in your driveway.
Also, the instructions were bang-on - thanks to the thread creators/contributors for a clear how-to.
