    4 Stars   Pretty Agressive Sound
    By on 6/14/2015
    I gambled on the Kooks exhaust, having not been able to find any good sound clips online. Overall I'm pretty happy with it, but there is a bit of a 'Trumpet-y' sound on light-load throttle up to about 2500 rpm. Cabin drone is also a bit more than I bargained for from 1700 - 2100 rpm. The system is pretty aggressive sounding, and sounds AWESOME at full throttle in the higher rev ranges (2700 to 6500).
    Four stars instead of five for the Trumpet-y sound and cabin drone.

    Yes, I would recommend this item to a friend!
