How did you come up with that? It is advertised to not cause any horsepower loss or performance issues. All the reviews I've read customers have zero horsepower loss nor performance issues.Be aware that the Kolpin style will restrict airflow which will reduce horsepower.
I have the Benz and I thought it really quieted mine down but do feel a little loss in power but not much. To me the power loss was out weighed by having a machine that I could stand to ride more than 15min.
I really need to quiet down the RZR for when my kids are inside. Has anyone used either of these products? If so, which do you feel quiets the exhaust down the most? Are there any other products out there that are better?www.rzrforums.net
