So guys I ordered the TBE from Perrin. It should quiet down my car a bit by scraficing 10-15 hp. Chances are I might get more wtq in return. Ive getting opions that the Perrin TBE is at around 95 db which California street legal sound level. I might add a resonator in the future for Laguna Seca (92db and below).
