A California model was used for testing, 49 state bikes will produce higher figures.
The high and low versions of the Holeshot pipe make nearly identical power.

Note: These are true numbers off Dale's in-house dyno. The Holeshot compound is about 200 feet above sea level and the dyno room stays a constant temperature between 70-80° F. The above results were also achieved with Dale's tuning, which is a bonus.

Be aware that dynos, dyno operators, conditions and bikes can vary 3-4 hp, so this should only be used as a reference.
