Default Side pipe decibels
Anyone have any experience with the side pipe inserts advertised online? I'm trying to lower the sound level without choking the motor down. I've seen the Spiral type, reverse flow type and glass pack. They all say how great they sound but never give any decibel reduction numbers. Can anyone tell me about them from actual experience? Thanks, Bill
