The bgm PRO Big Box Sport exhaust is based on the Big Box V4. We call it Sport, because it brings more power over the complete band on all comparison engines.

This makes the Big Box Sport the most powerful Big Box system ever made by bgm. The increase in performance was achieved by redesigning the internal damper chamber. This has made it necessary to install a hidden silencer under the engine.

The exhaust body is compatible with existing manifolds and the box itself can be easily converted. The box is available with manifolds for the following engines:

• RT195, RT225, original cylinders, Granturismo GT186, GT200, GT240 Mugello, Rapido, SR and all other cylinders with oval exhaustTS1
• 200, TS1 225, Monza and derivatives with round exhaust, the appropriate exhaust flange is sufficientFor
• Quattrini M210, here it needs the appropriate Quattrini manifold and flangeFor
• Simonini cylinders on appropriate cases like the Killercase, here it needs an appropriate manifold and the TS1 exhaust flange

TS1 flange not included
