I've spent a lot of time reading... too much info... I thought I'd make a post and ask... - What's wrong with cheapest ebay has to offer? 'Type Approved' - they're ALL type approved!! - After fitting, should I get an MOT done!!? Or maybe just the emissions tested?? Or is the worry many months after getting fitted? - After fitting... what should be the FIRST step? To buy a protection kit? Best to get the fitted WITH the new cat converter?? (Or... will the thieves NOT be interested because it's a cheap replacement?) - Protection kit - why aren't these widely available? Where should I buy from? Why can't I find on ebay or amazon? 1 website: £99 - £350!! Amazon, I only found this: http://www.amazon.co.uk/dp/B00HPZTCMA - not for sale anymore. - 'It's been happening in California 10 years ago'? This is a joke right? I thought Toyota had made a bad design and made it easy to steal. A company like Toyota should have ENOUGH brains to work out a way to make it impossible to have stolen? What am I missing? - Just out of interest... what other vehicles have this problem? Is this an epidemic on many many other cars as well? Is it less of a problem for newer Toyota Prius's? Have they anti theft design or something? I can't find protection kits for the Prius widely - but there are many for other cars. Thanks.
