guys like you, please consider the Super GT unit,
which has no valve control system.
It is all about weight savings, Power gains and Powerful sound !
GTC is for people who uses their vehicle for daily purposes who wants to/ or has to
make their vehicle sound quiet occasionaly (for many reasons),
yet who will not and can not compromise the performance and FUN !
