hey guys i got a gtm stage 1 kit with tial BOV in my car for the last 4 year its been running smooth love it knock on wood it stays that way! i always loved the sound of the HKS type 2 BOV and i want to switch them out. I was wondering if i can just swap them straight out or is there more to it than just that? also if anyone has a sound clip i would love to hear it on a G instead of Supras and Subies all the time! thanks guys really appreciate the help
