Re: What 3” muffler has the following characteristics:
Chambered mufflers generally offer a more aggressive idle sound which varies from chamber design itself
Straight Thru mufflers generally are quieter than chambered at idle but louder at WOT and typically provide more HP than a chambered muffler.
Larger pipe size often increase top end HP but gives up some low end TQ
Obviously what I like may not be what someone else likes and vice versa.
The FM chambered mufflers brought out in 60's is the "classic" muscle car sound. Not necessarily the highest HP muffler
Engine Masters has done comparison testing on HP/TQ and decibel readings at idle and WOT on all the muffler types. Turbo type making the least HP but mellow sound
