If there's one thing Cobra learned about the new Milwaukee Eight engine, it's that it really likes a large 2-into-1 style collector. The muffler section uses a PowrFlo 4.5-inch shell, packed with a sealed pillow of sound absorbing material which provides a deep rumble. Features a massive 2.5-inch collector, which allows for big horsepower and torque figures, especially when changing out the cam for something a little more aggressive. The rear is finished off with a brand new El Diablo style billet tip, which is powder coated in black and etched with the Cobra logo. Dual bungs are standard on this system, which makes it much easier to tune.
