so youre saying that the further back they are the less power loss there is???
is there a difference between in how there is a single inlet versus a dual inlet from a/b and e ?

I also thought have the mufflers closer to the engine gave the exhaust a deeper/more grumbly tone?

Well with option C you'll get more sound out of your mufflers.

I understand that a gas expands when heated and the muffler might 'rob' power, but that would only really be considered if you are using a restrictive muffler or one that flows right at the amount needed for you engine. and even then, the gas isnt going to expand THAT much to make a big difference, especially since you dont gain tons of power from a full exhaust.

if you have a good flowing muffler that can handle the amount of airflow for your power level, thermal expansion doesnt even need to be considered.

And why people then change them to higher flowing mufflers. Flowmaster is a 'HIGH-flow' muffler? magnaflow, borla, and the other straight flow mufflers double up most of the chambered mufflers on flow. (dynomax 2.5" straight through is 1133cfm)

The original poster said he is going to use borla, not a 'restrictive chambered muffler' and I didnt say the gas doesnt expand, it just isnt a big deal if you have a muffler that flows well.

So in summary of your posts, if you're gonna place the mufflers close to the engine, don't use a restrictive muffler like flowmaster

I'm not trying to be a jerk, I want to learn, but as much as I've learned about pressure and heat in aircraft systems, I've never heard of this..I don't see it as a problem. My flowmaster setup midbody sucked compared to my magnaflow midbody, but its because it doesnt flow well, not cuz of thermal expansion.

I voted b with a Magnaflow. I like b with true duals or at least a 3 in. pipe. That's if you have a 4.6 motor. With a v6 a smaller pipe would do.

I personally wouldn't use a single exhaust.

Since everyone's posting letters, I've got three letters for you.

I can vote the ART solution as well since that is what I have. You may have to tweak it a bit to make sure it fits right but I did the weld up kit so I had to tweak it anyway.

I finally got everything together to redue my exhaust. I am going with two high flow cats, Magnaflow midmount muffler (dual in/single out), then a Y pipe at the rear to some Borla tips. Should be install in a few weeks.
