Turbo muffler delete and blow off valve

[Aam]

Does anyone know where to get a turbo muffler delete and blow off valve for an Audi A3 8p 1.8tfsi 2007 model. I was under the impression the car comes with a ko3 turbo but the bolts that go into the stock turbo muffler aren't symmetrical. There are 3 bolts around it to hold it in, but two are closer together. I hope that makes sense... Don't know if anyone else is having the same issue. The engine code is byt

I have a Turbosmart BOV TS-0223-1063. Fits perfectly and works great.
I'm also interested in turbo muffler delete but haven't looked into it yet
