If you decide to run straights, keep in kind that the bigger pipe you use, the more mellow the tone will me.
2" sounds nasty on a small block chev, a 6.2 diesel, a v-6 Explorer, or a 230 straight 6, with split manifolds.
If you are going to do flamethrowers with mufflers, I'd use glasspacks, or steelpacks. If you try it with trash cans, and make a mistake, you'll end up with mufflers that look like pregnant puppies.
I ran straights on my 49 Chev, out 4" stacks, until I couldn't stand it anymore.
I took the stacks off at the elbows, and welded in blocker plates, with glasspacks on them. Most people don't even know I have mufflers, until I tell them.
The 4" stacks above the glasspacks gives a pretty effective expasion chamber, so you get nice orange rolling fire, instead of blue jets.
FYI I am a redneck. I built my own flamethrower setup, so that it would be safe, and easy to use.
