Remove the muffler to hear it more. Some say remove the cat too, it's even better. I did the muffler only and can get that special feeling every time I stomp on it.
62rag-Currently have 4" cat back with Walker BTM- you think muffler delete? Don't know if I want to delete the cat or just attempt to gut the kitty. It seems like my 06 PSD is in the shop quite often so I don't want to mess with the warranty. I do get a pretty good hiss as is, but I do have a neighbor that I would not mind pissin' off!
I run 4" MKO exhaust, no cat, no muffler and I still have a warranty.. Hell the guys at ford just love bringing that beast into the bay.. They roll out with the flash lights guiding it in :-P

Talk to your service department. Mine said leave the cat and anything upstream alone(yours could be different). It sounds good to me, and no warranty worries. I still have the rest of the factory sytem, so that's all I can compare to. Maybe try it on a temporary basis(possible?), if you don't like it, put it back........
