Exhaust head pipes must evolve along with the top end of the motorcycle's engine if they are to be efficient, make power and emit less heat than a stock system. Cobra modified the PowerPort by enlarging it to become a pulse chamber that accelerates exhaust scavenging to produce the kind of power riders expect.
- Even its cherry bomb shape, bulging from between the heat shields, gives a clue to the real power potential it offers.
- On top of that, this dual bung version includes 18 mm bungs up near the heads, allowing the use of wideband oxygen sensors.
- Perfect for use with the new Harley-Davidson auto tuner.
