VERY EASY...directions largely stolen from post by humfrz
Spray WD-40 on the nuts of old exhaust flange nuts (also on the threads that hold in the baffles if you plan to remove those).
Squirt some soapy water in and around the lower portion of the rubber exhaust hangers and you may want to yank the old exhaust back and forth to work that soapy water into the surface between the rubber hangers and the metal hooks that hang it from the car.
Remove the nuts on the old exhaust flange using a 14 mm deep socket or whatever fits (if you don't have a deep socket, you can use a regular socket, however the ratchet won't seat all the way down on the socket, so you have to hold it straight using two hands). Remove factory 'ring' style gasket on the midpipe.
Note: the exhaust midpipe will support itself during the change over
Coax the rubber support bushings off the old muffler using a piece of wood.
Hang the new muffler. Adjust it on the hangers until you get the flanges nice and flush (you do not want to 'jack' the muffler flanges into position with the hardware). Torque the supplied hardware to 25-30 ft/lbs.
You are done....unless you want to pull the baffles. The baffles make the muffler a little more quiet. If you want to pull them, find the bolt that holds them in...which is about 6 inches under each tip. Unscrew that bolt just HALFWAY and use it as a handle to jiggle the baffle loose. Then unscrew the retaining bolt the rest of the way and slide out the baffle. IF not removing baffles, check torque on retaining nut, 15 ft/lbs.
