Commonly Recognized As The BEST Sounding Exhaust For Harley-Davidson.PLEASE READ NOTES BELOW CONCERNING AVAILABILITY AND LEAD TIMES. This also creates an anti-reversion trap to minimize the amount of air rushing back in. The collector directs spent gases through acoustical dampening chambers, which creates a spiral motion upon exiting the pipes. With a patented collector design, only Thunderheader systems can produce their power, torque, and sound. Thunderheader head pipes are tuned to the proper length and diameter to produce maximum horsepower and an excellent torque curve. Between the unmistakable Thunderheader sound to its seat of the pants, dyno-proven performance gains, and its iconic look, a Thunderheader is always an excellent choice! Ramjet's has been selling Thunderheaders for nearly 30 years! Shortly after being introduced to the market in the late '80s, Thunderheader 2:1 exhaust systems became THE performance exhaust system for your Harley-Davidson.
