      You need a back box to pass the MOT, you can replace the original one with a smaller stainless steel one and it will be ok. Or better still twin pipes
      no you don't need a box for mot

        I had a Vectra 1.9 CDTi with Hybrid Turbo, FMIC and front de-cat pipe and a straight through exhaust to a small back box. I used to get a bit of a roar from the exhaust then />. Better than the tiny sound from a Petrol, would only do it when under load



        Heard a vec-c estate in Binley this morning with twin/quad pipes.



        No smoke, no poke and all that, but it did sound rather throaty.



        What makes the insignia so quiet? Is it the dpf?
