These numbers are on my factory motor sound
Bischoff mufflers.
Motor sound mufflers have a larger diameter
internal bypass tube that permits more back
pressure to run directly out to the exhaust tips.
The sonic difference is more pronounced during
maximum throttle or load. Some believe they
actually increase engine power. Although, many
believe the difference in power is only theoretical.

After talking to JTI Motorsport in the south of Sweden I know the increase of horsepower is 5-7, this was checked with dyno...
I am however, changing to fabspeed supercups because of the loudness
