Big Smoke -oil leak , boxster (pics)
 

Hi guys , I'm new here .. ! :)
I just bought a Boxster 2002, on high temperature, when I run it over around 4-5000 RPM there is a big smoke due to an external oil leak .. I put my hand under the car with my Kodak and I think I locate the leak, the oil leak on the muffler and sensors ( catalyst ? )
so what can you tell me about this leak ?
Thanks a lot for your help!!
