Let me start off by explaining my pre glasspack setup. My truck has the 5.4 btw. I had true dual 2.5 pipe with a boss custom x pipe and a rear cat delete and no mufflers. All this was done at a mustang performance garage in Hampton, TN. Awesome quality by the way. Even though it was practically straight pipe it sounded like no other straight because of the x pipe. However it did have the annoying rap of a straight pipe. Needless to say it was stupid loud. I had my exhaust that way for about 3 months until just last week when I had two 14 inch glasspacks put on it. I went to a local shop and said I want something to tame the exhaust and get the pop and rap cancelled out but for cheap. They installed and provided the glasspacks for $50. (It does help to be family friends with the owner) I am pleased with the results and for how cheap it was. Makes the exhaust a lot smoother sounding and deeper. I was pleasantly surprised. The only negative thing I have to say is that it created the holy mother of drone in my cab. But I can't complain too much as the drone is only present around 60 which I don't hit very often because most of my driving is city driving. This setup is only temporary as I am going to put either magnapacks or super 44s in a few months. I just wanted something quick and easy until then and to make me more adjusted to a quieter exhaust. I would recommend glasspacks to anyone wanting a super cheap muffler and a decent sound.

Go with a 18" Borla ProXS. Thats what I have with Longtubes and no cats with 3" pipe. I have 0 drone and its still extremely loud with out the pop or rasp.

Borla is the way to go, maggies being the next best thing. I have a single magnapack with 3 inch pipe with stock cats and I think it's plenty loud.

I've considered the Pro Xs but I'm afraid it wouldn't be loud enough for my liking since I still have 2 cats and stock manifolds. I like an exhaust to be both loud and have a good sound. If I'm not mistaken the Pro Xs comes in several sizes correct?

Yes, but the ProXS is a strait thru muffler. All it does is remove the pop.. With the ProXS my exhaust is almost as loud as it was with open headers, just not as annoying.

That's good to know man. My objective is to create the deepest exhaust sound I can get and still maintain a very aggressive volume level.

I have Thrush glass pack on mine, cheap but sounds decent.

They sound good for what they are. It still has the same tone straight pipes do but only a little tamer.
