Flowmaster super 44s

Hi guys I was wondering what your opinion was on the flowmaster super 44s I have a 1970 duster with a 360 2 barrel 727 trans and have the original exhaust manifolds with stock exhaust with the exception of summits house brand mufflers it sound good but I wanted to see if these super 44s are too loud or if they sound decent? Also my buddy has a set of thrush turbos he could sell me
