Yes, changing the design of a muffler can increase it's flow capability, but so can things like changes in pipe diameter, changes in the type and size of any other restrictions (just like the screen in the MAF), etc. And no, mufflers aren't just about sound. It's possible to muffle sound without restricting flow.

higher flowing muffler?? i thought they were all for sound... lol
a higher flowing muffler doesnt apply because youre replacing a stock "Restrictive" muffler with a completely different design. What they are talking about is if the "restriction" (screen if you will) is even needed in a closed system that will have the same design and if this screen affects the air flow in the tube. Im pretty sure it does provide MINIMAL amount of restriction.. but unless youre F/I i doubt its enough to free up any amount of power. Not to mention, everything in our car was put there for a reason.. we just need to figure out why its there and if it is needed/conflicts with our application/plans for our stangs.

If this were true, a higher flowing muffler wouldn't increase exhaust flow either.
...but removing the screen causing to much air flow and setting the code, the throttle body regulated the air flow so removing the screen cannot increase air flow since the throttle body regulates it not the screen. Even at WOT the throttle body is the restriction(this is why removing the screen does not free up any horse power).
If this were true, a higher flowing muffler wouldn't increase exhaust flow either.

They don;t, less restrictive mufflers decrease back pressure allowing more mass air flow not an increase in velocity.Actuall the flowvelocity probably decreases as a result of larger pipes (2.25 to 2.5) and the less restrictive mufflers

Well, I emailed the guys at tunable inductions, I am installing the #5 system. They design their system to run without the screen; claiming its purpose is only to keep debris out of the motor. Ill install it without the screen and see what happens.

Yeah, I don't necessarily agree with their pov. I believe its for "smoothing out" the air flow. But their intake doesn't incorporate it in the design, and I have the intake. So ill leave it out per their directions and see what happens. And yeah, what the hell would pass through the filter that wouldn't pass through the screen?
