Good afternoon everyone. I have decided for sure that I'm going ewg on my 04 sti. Going with a Grimmspeed uppipe and Tial 38mm wastegate. Now my question is which do i go with? Im looking at a choice between 2 the Tial MVS 38mm v band and the Tial MVS-A but not really sure what the differences are besides price. Any help would be greatly appreciated!
