THUNDERHEADER EXHAUST - M8 SOFTAIL

NEW X-SERIES THUNDERHEADERS 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. 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! Thunderheader head pipes are tuned to the proper length and diameter to produce maximum horsepower and an excellent torque curve. With a patented collector design, only Thunderheader systems can produce their power, torque, and sound. The collector directs spent gases through acoustical dampening chambers, which creates a spiral motion upon exiting the pipes. This also creates an anti-reversion trap to minimize the amount of air rushing back in.PLEASE READ NOTES BELOW CONCERNING AVAILABILITY AND LEAD TIMES. X-Series has 2" Diameter, Equal Length Head Pipe & Larger Co
