Had both my catalytic converters stolen off my E250 in Vancouver Canada, parked in the backyard of a mates house. Frustrating because the van wasn’t worth replacing them. But surprisingly it was legal to replace them with straight pipe. Obviously ethically dubious, due to increased emissions. But a better option that scraping the vehicle prematurely and purchasing a new one. Either way. I’d be looking at the demand side. The thieves aren’t melting them down, they’re flogging them for cash. Who’s paying cash for clearly hastily sawn off catalytic converters in bulk?
