This was my point in that "exhuast opinions" thread. Roush sound good with cats retained, but once you get rid of em, they are just overbearing.
Id like to hear either MBRP, JBA or Bassani axelback with your setup.
Gt500 sound great but everyone has em.
Edit,
JBA AB is only $10 more than the GT500's...im surprised i dont see these as much, they look good.
They were insanely loud...I mean so loud it was comical. I could not wait to get home and take them off. Stockers, courtesy of Turbosixx ,are on now and harmony has been restored to the force.
I am not sure where I am going next. I used to want the JBA, but I heard they droned. I can't deal with that. I have had GT500s, I may get them again. What I have been really thinking about is Dynomax Ultra-Flows. They have an axle back that is affordable.
Here is how it was revving up:
