Sound is great! Install took about 2 hours but I enjoy wrenching so found it fun (make sure you have t-55 bit. Had to take quick run to parts store). I'd say weight savings and power increase are noticeable. Only issue is that exhaust spits out a little black smoke which I believe means it might be running a little rich. I found this strange since I followed the recommended process of leaving the engine running until cooling fan turned on before riding, which I was told allows the ECU to learn of airflow changes and adjust itself. Would be great to hear from someone from BC about this! Even if remap is needed I'd still say it's the best product I've installed on my t-120.
