Long time member but very infrequent poster here. I have been out of the Z scene for a while and I am looking for a cat back exhaust upgrade. So far I am only really finding them from Magnaflow or Specialty Z. Does anybody else still make a good cat back for a 1991 TTZ that I should consider? What are the differences between x pipe or h pipe? I understand that resonators decrease noise. I want a nice exhaust note not something overly loud to the point of being annoying so should I get resonated? Does the open make more power? Looking for your recommendations suggestions and help with these questions. Thanks in advance.
