Suggestions on a louder exhaust?

Right now I have a si/do muffler that measures about 13" long. Its center in dual out. I'm not really sure the brand, because my parents had it put on as a Christmas gift to me and I didn't get any say in it. I looked on the bottom of the muffler and there are no markings so I have a feeling the shop used some off brand muffler. Right now its decently loud, when i take off if i can keep rpm at about 2,1-2,200 it gets pretty loud, and on highway moving in between 63-69 mpg it gets a pretty loud drone. But other than that its pretty quite. I was wondering what would be a good exhaust that has a nice deep rumble that sounds good at low speeds such as take offs and such, but isn't obnoxiously loud when cruising down the highway at 70, i still like to hear it but not really super loud. I figured someone could give me a suggestion on a good muffler for this. Thanks yall!

Just hack off the muffler and tail pipes. With stock cats, it should sound decent and loud but not obnoxiously loud. That's also about as cheap as you can get.

Sounds good. If I decided to do this how would I want to do it. An x pipe? I pull a lot of trailers and stuff, will this effect the performance of low end torque? Sorry for all the questions, I know about nothing about exhaust.

Definitely an X pipe, best for towing and to balance the scavenging the best. Your performance will not be effected, I would suggest 2.5" piping since its gonna be straights, will sound better, not not quite the best for performance down in the low rpm range, I would definitely have smooth bent piping done. 2.25" straights sounds like absolute s*** to me, too poppy, raspy, and a little quieter.

Well i already got some piping under, so i think i may be able to salvage it. If not i think i may do it all myself. I can weld alright so i think I could install it all. Who knows, i may decide not to. I'm in college, but going to the local community college just down the road (got a full ride there for 2 years) so ism still living with my parents, gotta okay it with them first. If they say no once i move out i will for sure.

Here are some vids I took so you can hear what my current exhaust sounds like. The in-cab vids where with the windows all open, and i really think the camera makes it sound louder than it is.

Straight's FTW! This is what my true dualed setup sounded like on my 04 F150 with the rear cat's removed. It's 2.5" pipe with 4x18" tip's. I've had my exhaust changed twice since this setup and am currently running 2.5" pipe with 3.5x 18" tip's. The exhaust sounds deeper at idle with the 3.5" tip's.

So if i understand these trucks come with 4 cats? Would the exhaust be louder if i just removed the 2 rear cats? I'm not sure I need to look up under and take some pics for you guys so you can see what has been done to it already.
