what is the difference between eisenmann race performance and sport performance

[Nate@IND]

The Eisenmann Sport and Race performance share the same external design. The Eisenmann Race performance uses straight-through technology. While the Sport performance has internal baffles and sound deadening materials. The Eisenmann Race performance reduces backpressure by 32%. Most Eisenmann systems for NA motors in the past have increased hp by 8-10. The Eisenmann Sport performance is much quieter than the Race and reduces backpressure by 25%.

weight of the muffler = apr. 21 kg

RACE-Version:

moving vehicle = apr. 95 db
stationary vehicle = apr. 102 db at 6.225 1/min
value of backpressure = apr. -32%

Please note these values are always depending on external circumstances as feg. barometric pressure, outside temperature, abrasion of the pre silencers, abrasion of the cat-converter, etc....
