Im very interested in seeing the end product, ive been wanting to do the same thing and experiment with all different designs and stuff. Do a search, theres Lots of fancy talk you can learn about it. sounds waves bouncing one way and canceling each other out on the rebound etc.

THere is a much simpler solution to all this, and something lotus have tried. 
Simple make a sound recording of you car as it gose through the rev range with open exhausts. then invert the sound wave and play it back at the same volume as the exhaust. The sound saves cancell eachother out totaly and you have a car that has no exhasust but goes like STINK!
Lotus acutally made a very boring toyota, i think, sound like a V8. and it worked!

i will have to go whit no off set also with out any way off knowing how the gas will act inside muffler its more or less a shot in the dark of what you are getting and if you are going to put the time into it why not make it right or not hard to chang in this why the more you play with it you can start to see what happens with each different set up

Is it a muffler to keep her quiet ? lol
I've spent quite a bunch of time thinking of muffler designs as well. The bottom line is it's gonna cost you more to make it than to buy a mass produced muffler. The exception is if the masses do not make a muffler that fits your needs.
The designs by Flowmaster are all computer designed. You have to get the spacing and size of the baffles just right in order to cancel out noise. So that style is way too complicated for me to work with.
I think the Magnaflow style is much easier to design. Like below.
I was looking at custom inlet and outlet angles at first. I ditched that idea. Now I'd like to make some really thin mufflers, about 2.25" thick. Spintech makes some, but are $140 each. I was thinking of buying some Magnaflows for half that price and then slice them open, move the material around, flatten it down to 2.25" and then weld it back up.
I basically would mount them right under the floor. Headers to muffler to dump. Another thought is to mount them behind each front wheel and have them exit right in front of the door. Mercedes SLR style.
If you need internal pics of just about any muffler out there, just let me know. I have lots.
