I wouldn't say it's really loud but loud enough to hear it inside and outside the car, sounds pretty cool though, unless it's not ment to make that noise
Only way i can describe it is it's like a tsss sound when letting off the accelerator, it does it in all gears aswell
What do they look like when fitted? Pretty sure i havent though, Could this be a sign of a split dv?
Who else has a dv sound on there standard cupra? Just looking to see if this is normal
