Hi, I just had a new Milltek cat-back fitted to my Cupra today and it sounds great, but there is a really weird noise coming from the boot.
Looking closer at it, there's some rubber flaps that look like vents in the tyre well which flap like crazy at certain revs, almost like air blowing through them..
Does anyone know what these flaps are for, and could I just tape them up to stop the noise, or is this something that shouldn't be ignored?
Any advice is much appreciated,
Thanks.
