I got a Blitz Nur Spec R exhaust fitted today at a rather dodgy garage. I left the car with them when it was cold and in full working order, then when i collected it an hour later, it was up to temperature and my intercooler water spray had suddenly ran out, then after driving for 15 mins the engine check light has now come on.

Have they destroyed my car or is this a typical problem of fitting the said exhaust to a version 5 STI type R ?
