FMF full system

I'm considering putting a FMF high flow header and Q4 exhaust on my 2006 WR. Anyone running this system and was there much difference from your uncorked stock system? Thanks in advance.

I am running the power bomb and the Q4 on my 04. I switched from the uncorked stock because it was so loud and drew to much attention. I think the power bomb makes up for any power loss and the Q4 is very quiet especially if you have noise issues like we do in Oregon.:banghead:
