    Hi

    I've just had a magnex back box put on my car and also I removed a part of the air box which reduces intake noise.

    Sinse I've done that their has been a strange noise when the car is underload at low revs, but I put the part of the air box back in just to hear the exhuast on its own and it didnt make that noise at all.

    Its sounds like a vibrating/popping sort of noise. Cant work out if its back fireing or if its the exhuast vibrating

    Any one shed some light on this?

    Sorry if I'v posted it in the wrong place.

    O the car is a 94 VW Corrado 2lt 16vl

    Thanks

    Sounds like the exhaust moving to me.

    It might be, but i looked under tha car and tryed to move it but it wasnt easy.

    I also looked for anything loose it could be vibrating against but there wasnt anything

    The part you removed from the air intake is probably there to prevent noise of a certain resonant frequency that can be produced due to the size/shape of the intake piping

    Is it standard otherwise?
