I rescently bought an Extreme Audiopipe (200 watt) and it is awesome. The wife was against it at first but changed her mind after the first ride. My bike is very loud and she could hear it very plain and loud even when she was about 4 bikes in front of me with a helmet on. I ride in deep mud and water alot and it proved to hold up to what they claim during the first ride. I got it completely under water in a river in Harlen County Kentucky and it never missed a beat. I got a waterproof box for it at Bass Pro Shops.
