i'm deciding very soon to buy one of the two. I'm confused because I have heard neither of them in person, only in sound clips. Im not looking for performance either.

Some Pros vs Cons.

The SP2 sounds really close to stock? Is it worth it if there is not much of a difference?

The SP2 sticks out atleast 3-4inchs? Doesnt sit flush?

The HFCs are bit spendy.

So many pros vs cons. let me know your knowledge of these products.

Thanks!
