the badger pipes are a rip off IMO, made no difference on my mates S3, they are bigger but the ko4 turbo inlet is small, so the badger pipe has a big boss with a tiny hole in it for the turbo, unless you got it cheap, a decent silicone TIP would have been as good. i dont care hwat tests they claim to have made to them, sometimes people tell you what u want to hear to get a sale
what i did with my RS2 turbo, is cut my silicone TIP in half and i have a metal pipe same bore as turbo right into it, so my tip is big right up to the turbo and the turbo inlet is the same size
id rather be spending money on a 008 and replacing the breather lines for silicone ones as these a prone to give these engines issues and boost leaks = loss of power
the aggressive low down power delivery you mention is down to the map
