73RS, dual flowmasters that make you def after 15 miles and you wear ear plugs? Lol come on I think your exaggerating (sp) a bit because on my truck with a 454 we have dual all the way back flowmasters and I have them right under the cab right after the muffler pointing down before the rear differential and it's not that bad and not even on the highway. Either that or I am def... well I am already a little anyways.
