the lower the number, the louder the tone. the 40 series is the loudest, and they get progressively quieter as the # goes up.

I also found a 30 series.

Hay i have a quick question about the 40 series. Is the interrior noise lvl very loud. Like getting a headache loud or is it just the right tone loud.

I know this has nothing to do with your original question, but to me flowmasters make a bad resonance sound at several different RPM ranges, and a magnaflow muffler doesn't, and sounds better in general.

In the performance series, the 70 series requires normal speakers and stock audio. The lower the number you go the larger the speakers and more powerful amplifier needed to overcome the resonance to the cab. At some point you will also need wireless headphones with microphone to speak with other persons in the cab.
