BGM PRO BigBox Clubman V4 exhaust for Lambretta S1 + S2 + S3 + GP DL + Serveta. The BGM Pro Clubman, with the low noise level and simple design of a standard exhaust, offers the same power and performance of an expansion chamber exhaust. Ideal for a discrete but fast ride. Unlike most expansion chamber exhausts, the Clubman is characterized by a homogeneous increase of power. The high torque already reached at a lower rev range enables a stress-free and relaxed ride, while the original design of the exhaust can be perfectly combined with the look of a standard scooter. The wide range of power allows a high maximum speed. 

The following features of the V4 model have been improved: 
- brazed brackets
- reinforced brackets 
- improved insulation

The exhaust still features these great points :
- same performance of an expansion chamber exhaust
- low noise level - larger volume of the exhaust body 
- great ground clearance
