Just had my new exhaust fitted on Sat, and there was a problem - the sensor that goes into the cat pipe had seized into the previous cat replacement pipe on the car..... as a result it had to be cut. I've been told by a couple of people I'll be alright running the car without this as its not needed when the cats not on the car, but I've also been told id is needed.... can anyone help out, who's right? :?
