oh yes!,,, spend 3 and half hours putting the Gruppe M on my car...(DIY)
really please with my self, because this is my first time doing this kind of stuff!...he he!..
it wasn't that difficult and its just matter of time!,
didn't have time to test drive it yesterday... went out and drive around today... and i just love it!.. its better than the factory one!.. however, it doesnt sound as good as the HKS one!.. when v-tic kicks in!,,the HKS on just sounds amazing and makes you wanna drive faster, faster and faster!!...
the Gruppe M sound just little bit louder than the the factory and it doesn't flat spot like the HKS does!.. which is really good!..
...the difference between the Gruppe M and the HKS is just the sound and the power it gives..!.if you dont want to spend too much money on an induction kit, go for the HKS..
NOT HAPPY WITH THIS!!!
