A radio circuit that isolates and creates an exact opposite waveform to the clanking, bonking, scraping or cyclic grinding noises emanating from your poorly-maintained vehicle. A fast processor and full radio speaker integration ensures only trailing vehicles will know of your expired compressor bearings, screaming brakes and dragging exhaust. A turbo boost amplifier feature is available for when the muffler finally lets go.-- whatrock, Apr 16 2016random, halfbakery
