Put basssani cats on today and the sound is purfect ,just what I was looking for,its those metal matrix ones,i think thats what there called ,when you look inside its just a treated screen,looks like it will flow good and only around 3 hp lost.But it feels strong went for a test ride today and it was hot out and the car felt like I was driving at night with cold air.I was pretty impressed.Feels like i got more bottom end torque and couldnt really tell if i lost any power on top.Guess i'll find out at the track.Pretty happy with the sound its atleast only half as loud and although louder than it was with factory h-pipe and borla stinger cat-back..So it looks like i'm going to pass the decible level at the track and not have to get another cat back 
sat night is looking good though.Your wright Bassani rules 
Sounds good though
