1st comparison: Pictures show them side by side
2nd comparison: Weight. Short Tubes are little over 4 pounds lighter each.
3rd comparison: Cold start
4th comparison: Revs
Test vehicle is a 2005 Chevy Silverado 5.3 with Flomaster 10 series exhaust, stock cats
Personal opinion, I couldn't hardly tell a difference. The owner says you can kind of tell when getting on interstate.
