1984 Firebird SE 350 crate with magnaflow muffler

This is my daily driver so i wanted something kinda mellow at idle and cruise, but like any hotrodder, i wanted it to talk to me when i got on the loud pedal. Well this muffler does just that, it's nice and mellow (a little deeper than stock but lower db than stock!) at idle and cruise but absolutely SCREAMS at WOT. GM 260hp 350 crate, hooker 2460 shorties, Walter Racecraft y-pipe and 3" single back to a single in/out magnaflow muffler dumped under the rear bumper.

glasspack vs flowmaster
this is a comparison of the two on an '87 firebird with a 305. the flowmaster has a harmonized sound because of the dual outlet so try to keep that in mind. unfortunately im stupid and dont know the brand of glasspack nor the series of muffler.
