I have a 71 sprint Veloce. I tried the following on my Sprint Veloce:
1) Stock (Also the smallest in size along the Malossi) 2) Sito plus (very large and bulky with poor clearance but decent performance. Noisy) 3) Polini box (10-15% larger in size than the Malossi or stock). 4) Malossi box (the smallest in size, very compact). Noisy deep 5) SR3(SIP road 3), same size as the Polini. Not too well design because the elbow hits the ground 6) Lefty Boomstick. it clears very well under the left cowl For power the absolute best was the SR3. I tested it over and over and over with two GPS, a tachometer and a acceleration instrument device(Dragy). The SR3 is just well above the rest in power/torque. The second best was the Polini closely followed by the Malossi. Although the top speed did not change much the acceleration improvement was significant. ![]() |

I'm happy to see your in use exhaust comparison, and it also makes me sad to see the Vespas tipped over on the ground.
