It brought down the exhaust note but barely did anything to the rasp and hiss. I love the F.I. exhaust but I need a change.

I was looking into several exhausts and was hoping those of you who have these exhausts would give me some feedback on the sound and performance so I could choose properly.

I was looking into:

HKS hi-power
Greddy Ti-C
Greddy Evo3
Greddy SP
Injen CBE

I would appreciate it if you would give some comments regarding those exhausts.

Thank you
