Whoever said glasspacks were louder than straights evidently have no idea what they are talking about.After glasspacks get carboned up they tend to get louder,but not as loud as straights.On the newer vehicles with catalytic converters you can sometimes get away with straights,because the converters tend to quiet the exhaust down a bit.Put a set of straights behind a straight 6 with split manifold,or headers and you sre guaranteed to see red and blue lights flashing in you rear view mirror.
