Abstract (en)
[origin: WO2007030099A1] The present invention lowers the noise output from an engine while increasing performance. The present invention's shape allows the bores (20) to push exhaust backwards, away from a motorized device without combining the air streams. The rifling (30) of the bores (20) creates a vortex of each exhaust stream, further lowering the decibels and increasing engine performance.
