Im looking around for a new catback, I had the Greddy SP catback and i just blew it apart about a month ago. Now the car is way to loud and i miss the mellow sound of my SP. Im just wondering if the Racing Beat catback performance is better or worse the the greddy sp?

 

It's probably close to equal, but not better performance. It seems that the RB is an excellent design that combines both very good performance with reasonable sound levels. Exactly how much performance difference will depend on the car, but it's safe to say some pretty powerful FDs have been run with an RB dual.
