Swapping out the muffler alone will hardly change the sound volume at all. The catalytic converter muffles most of the noise.
I've witnessed first hand all combos.
Quiet: stock muffler w/cat
Quiet: aftermarket muffler w/cat
Loud: stock muffler w/link pipe
Loud: aftermarket muffler w/link pipe
Not sure: any exhaust with an actual feline cat stuffed in it.
