The name Tubi might be new to a lot of you but if you’ve ever owned a Ferrari or Lamborghini you’ve heard it before many times.  That should give you a clue to the kind of quality they go for so if they make a muffler for say, an Audi RS4 you better believe its going to be good stuff.  I just wish they had a sound clip because I’m sure this thing is pure exhaust music!
