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 repositioned. The box is available with manifolds for the following engines:
The proven features of the Big Box V4 have of course been adopted:
