thanks for posting.
I had my cat stolen yesterday when it was parked in N London (N15).
I just rang Toyota about the catloc which costs between £200-£250 - they couldn't say if it would fit on a Lexus. Apparently Lexus are looking into manufacturing their own version of the catloc. https://blog.toyota.co.uk/catalytic-converter-theft-how-to-protect-your-car
They say the waiting list for a new cat is about a month, apparently loads of cats have been stolen in the last couple of weeks.
