imo the cnt looked slightly nicer to me because it had rolled tips and seems to take a little more rasp out from the exhaust vids i saw online. now thats not considering the new topspeed system that just got released either. but i can tell u that with the cnt cb and test pips that there is zero hint of rasp and keeps the tone mellow enough that nobody even realizes the car is running tp's

both systems seem to be very nice inexpensive systems. imo much nicer than the agency power or megan systems which are around the same price but sound AWFUL
