How to remove stock exhaust tips?

[Kameo]

Now, before all you veteran modders pounce on my modestly-styled CX-7, let me say that I'm new to this wave of pimping up my ride...! (whistle) After getting custom 20" rims I'm yearning to upgrade my exhaust tips. Only thing is that I can't see how to remove the stock tips--I can't see any screws/bolts, and I don't seem to find anyone posting this How-to. Any good tips?

This is what I'd love to get on my ride: http://www.carid.com/universal-exhaust-systems/magnaflow-single-exhaust-tips-1521227.html

Kam,
Usually you need the help of a local mufler shop to do this, Need to cut off with a reciprocating saw or torch off, Also can use a hack saw but I recommed a professional Muffler shop to remove old exhaust tips and weld on new tips, Tips that are screwed on will come loose and fall off from vibration, No good, Muffler shops are a great source for this type of work and many are very skilled.
