I have heard outrageous prices being quoted for the pse in Canada. I'm in Toronto and both pfaff and downtown want somewhere in the range of C$7000 total installed cost. It's rediculous. I'm planning a trip down to one of the us dealers in the spring to have mine done. Even with th exchange rate if you have this done in the US its about $3000-$3500 cdn.
I was told by one of the service advisor in Toronto that they can do a modification on the muffler for 1800 that is exactly what porsche does with PSE except you don't get a switch
