Had my exhaust system fitted yesterday so the exhaust fires out through the exits on the overfinch bumper. When the guy cut the system off just behind the DPF, he started it up, and it sounded no different to what it did with the rear silencer on... so we just fitted straight pipes out to the back with no rear or middle silencer, and it is still whisper quiet. Quite unbelievable for an engine of that size.
