I plan on adding a supercharger in the future but with the noise issue it is making the car less enjoyable to drive. I appreciate what some of you have said reguarding loving the exhaust note and not listening to the radio etc. But I do love the radio. Thanks for the imput!!!

I think you stepped over the line with the HFC's. From Vids I've heard they make a substantial change in the sound level. I have a Stillen Cat back (which seemed pretty tame) and just added a custom intake (which made it just perfect for me). After reading reports here I'd probably have the same issue as you if I went to the HFC's. I think I'll hold where I am...
I think you're going to have to sacrifice one or the other to get the sound levels where you want them.
