LT's or shorties?

What should I go with?

I was orginally planning on getting LT's to extract the most power from my car but is it worth it? Not only have I read that it's generally a pain to get on, and also that it would sound horrible with a x pipe, muffler combo (what I wanted to do) I heard a sound clip of a car with FMS shorties, Dr. gas x pipe and spintech sportsmens and it sounded REALLY good. Now if I get that extact combo but I put some BBK LT's in there, how will the sound differ? For best or for worst?

Any help is appreciated, thanks. As you can see, I tend to overthink things, lol.
