The BGM BigBox Sport is a thoroughbred racing exhaust, in the unsuspicious design of an original exhaust. It positions itself as a clear alternative to eye-catching and mostly loud and large resonance exhaust systems. The high level of motivation clearly sets it apart from other boxing systems. Designed for performance-oriented drivers who appreciate the benefits of an inconspicuous vehicle.

Performance diagram (BGM1010SP)

Powerful engine concept required

Like any good racing exhaust, the Sport Box requires a powerful engine concept in order to develop its full performance. In the environment of cylinders like the Quattrini M1X and Co., it offers impressive results. It also supports engine outputs above 25PS without any problems and pushes ahead with full torque. Despite its high peak performance, the Sport Box gets in early and also enables comfortable driving.

Due to its consistent design for a high gas throughput, the BigBox Sport is not intended for use with near-series engines or tame tuning cylinders. It needs a clear and powerful outlet impulse to fill the large volume and the thick elbow of the Sport Box with life.


  • Original optics
  • Quiet
  • Top performance like a resonance exhaust
  • No performance hole
  • Broad speed range
  • More top speed
  • Very unobtrusive
  • Also fits rally / sprint without modifications
  • Solid construction with clamp on the cylinder
  • Handcrafted in Europe


  • Not for vehicles with 8 inch tires (ground clearance too low)
  • Not for near-series engines

The elbow is attached to the cylinder using a clamp. Compared to loose fastening with an O-ring seal, this results in the best stability and prevents damage to the outlet flange. A long spacer should be used on the rear shock absorber for optimal ground clearance.

Conclusion: pure understatement. Performance like a racing exhaust, optics and sound similar to an original exhaust.
