BMW E60 M5 Muffler Delete: After #2 HD

This is an interior sound comparison of Muffler Delete (only stock mufflers taken out). All windows are rolled down (opened): 1. No drone 2. Cruising speed is relatively quite with all windows rolled-up 3. Great F1 sound noticeable above 5K RPM Update: 4. Weight lost in Lbs: Stock Mufflers (75) - Doubled wall Exhaust Tips and Stainless Steel pipes (15) = 60 (approx.) 5. Drive feel: Yes, I could feel the weight loss, high RPM horsepower gain, low end torque gain. 6. Average cumulative MPG went down from 16.3 to 16.2 so far. 7. Subjective Opinion: I used to love the car only when driving it fast, but now I can enjoy it just by low speed cruising to hear the exhaust symphony. In my biased opinion, my car sound better than many/most of Italian supercars.
