1971 Monte Carlo with 454ci engine, 3" original Flowmaster 50 series mufflers, no tailpipes

This is my 1971 Monte Carlo. The video clip is for sound comparisons for different Exhausts. The engine is about 9:1 compression and has a small hydraulic roller cam (224/234 deg @ 0.050", .527"/.544" lift). The intake is an Edelbrock RPM air gap, and the carb is a 750 Mighty Demon mechanical Secondary. The headers are Hooker Competition headers with 2" primaries and 3.5" collectors which go into 3" dual Exhaust with 3" 50-Series Flowmaster mufflers which end right before the rear end.
