Exhaust BGM PRO BigBox TOURING V2 (BBT2) Vespa PX200, Rally200

POWER & TORQUE
The power level and ground clearance were significantly increased compared with the previous version. The proven features of the previous Bigbox Touring system have been retained. Thus, the buffalo-like character with rich torque when starting remains, as does the high and early power peak. However, the power band and the maximum power/torque values are significantly higher. The 200cc version of the new Touring V2 has again significantly increased power in the middle and upper speed range compared with the previous version. It is therefore on a par with the well-known Polini box.

FREE BREATHING
The internal structure was also changed. The connecting tube from the resonance chamber to the damper chamber was enlarged. This means that even very powerful engines can be operated continuously at full throttle without any problems, without power fading.

THERMAL RELIEF
The tailpipe has also been enlarged from Ø18mm to Ø20mm. However, to reduce volume, the BBT2 has an inserted tailpipe with Ø18mm. This cross-section is sufficient for almost all engines up to 190cc and approximately 22-25HP (depending on engine design and achievable speed, this value varies). Anyone running a very strong setup at high continuous speeds can remove the Ø18mm tailpipe, which is fixed with only one spot weld, and then has the full Ø20mm cross-section.
