I can’t say enough about my Tubi. Love it. My friend owns a dealer that just got in a ‘14 R8 V8, and I don’t know what aftermarket is on it but it made me feel even better about the Tubi. At cold start it’s pretty loud, to the point where I parked too close to an E Class and set off its alarm twice in a week (never happened before), but when you wind it out above 4K RPM it sounds amazing. If it didn’t, as I don’t like loud exhausts for the sake of being loud, I would’ve put the stock exhaust back on which came with the car. The scream is really nice.
