Hi, my wife's cat converter was nicked from her Shogun - car parked outside the house; we didn't hear a thing. My local garage says it can take a matter of minutes to remove one. They also said none of the advertised solutions (cages, welding etc) works - some of these solutions are also costly. Apart from putting your car/4 x 4 in a secure garage is there any solution that you Cayenne owners have used/researched to be extremely effective.4 x 4's, vans etc are targeted as it's easier to nick the cat converter due to its ground clearance.
