I bought a badger5 v2 80mm tip and jetex filter got it fitted last Sunday and all I can say is wow.response is sharper,the noise from the air rushing threw it is great but does encourage you to be a bit of a hooligan .there is a good increase in torque over the full rev range.it feels like car has had another map.If anyone is thinking on buying then its a no brainer.i am over the moon with the results
