Lm vs Td Loudness
I can only assume that the sweet thunder true duals will be run off longtubes, so to answer your question...........it's gonna be hella louder than stock manifolds/cats/loudmouth. Even if you decide to do a catted tru dual setup, the headers alone will make it much louder.....but it'll sound badass!!! 
It will be louder but more refined until you go WOT then it is just plain LOUD. I went with 24inch sweet thunders to try to get a bit deeper sound. It is a bit tamer than 18inch but at WOT they sound the same.

With TD's anything over 3k when excellerating will be loud...I have TD's and had them dump at the alxe, it's loud at idle, but not to annoying....but once you start going through the gears and over 3k it start to get really loud.....I am actually going to change my set up and go with something else....But not sure what yet...I may just replace the bullet mufflers with......**** I dont knwo what with.....LOL

You can have cats on the texas speed rumblers td setup? If so does it sound better? Im kind of looking for the LM sound or a sound like what a mustang(sorry) sounds like. I just want a nice sick sounding setup.
