Does anyone know what kind of mods those cars got? exhaust is totally different i think..and for sure thats not the only power enhancement over street version...

Thanks

Long-tube headers, no cats, no resonators, ECU/Software tune, fuel cell. Besides the equipment needed to be a Safety Car, pretty close to a street Black Series.

Sounds just like mine....As SMP stated, they can all sound like that with longtube headers and a cat delete.
