I don't believe this is correct, . . . . Uhhhhh, . . This is 100% wrong.
Exhaust gas and sound waves are two completely different things. You never want to make an effort to slow or reduce the exhaust velocity. You will lose power (backpressure). The mufflers job is to absorb and/or cancel out sound waves. The better it can absorb/cancel sound waves relative to maintaining a free flow, the better it is at its job.
Mufflers like glasspacks absorb sound waves and mufflers like Flowmasters cancel out the sound waves inside small resonance chambers within the muffler.
(just as an aside, . . . . good backpressure is like good cancer)
