Straight through mufflers can be effective. They do tend to be louder at heavy throttle than a turbo style muffler with a bit harsher, raspier, and louder tone vs. the deeper, throatier tone of a turbo style muffler even if the volume is the same at light throttle.
These are generalizations. Muffler design is math heavy and precise and well beyond my capabilities.
Per the Flowmaster rep moving the deflector plates inside .050" can hurt the performance of the muffler!
Although I have made mufflers from scratch and some of them worked well the success was more by luck than skill.
Three chamber Flowmasters utilize a Helmholtz resonator. that is the third chamber.
When you blow across the opening of a bottle the tone you hear is the frequency (or one of it's harmonics) that it can cancel out if it was used as an Helmholtz resonator.
