Re: Quiet exhaust system for 454

switched to flowmaster 40's, cause they were on my small block '68 910 and sounded nice.
they turned out to be just as loud as the magna's.
next was a set of 50 series, still waaay too loud for me.
for the last few yrs now i been running big block 70's and i like them. mostly quiet when not into the throttle, but still barks when i step on it.
Do you find the 70 Series to be closer to stock or still pretty aggressive? The objective for me is to keep the truck quiet (as this is my daily driver I leave my house very early in the morning and come home late at night) while still having great flow. Do you wish they were a little quieter or they are a good fit?
