I am sure that this question has come up before. I have searched the archives and came up empty. I have a 1989 328 GTS in need of a sound injection. I have limited my choices down to a Tubi or Borla system. Can a few of you give me a little advice on which way to go? The Tubi is a few hundred bucks less. The Tubi quality is seemingly superior. How about the sound? I am looking for loud and healthy. Any help would be greatly appreciated.
