    Turbo howl (coooing noise) for a3 2.0 tdi 140

    Hey everyone, can anyone tell me how to make the turbo howl louder? I've just fitted a catback system which has improved it a bit, but want it to be louder and more noticeable, is there a simple way of doing it? Thanks.

    You just spent x amount on a system to give you nothing in terms of performance. The CAT is the most restrictive part of the system and diesels do not require it for the MOT

    I was going to get a decat but I think it sounds too rough and noisy, the catbacks given it a lot more poke which I'm satisfied with and it sounds decent too, but I want the turbo howl louder if that's possible? Or is decat the only way?

    I'll look into it, have you got a full system or just the downpipe?
