Chrome. Cobra's Speedster systems combine traditional styling and modern performance technology. These Speedster Shorts offer double barrel shotgun-styled pipes featuring full-length, 222-degree heat shields and finished with a set of Race-Pro style tips, black tips on chrome pipes and chrome tips on black pipes. The Cobra PowerPort technology helps to increase overall power from idle to redline, delivering the type of power increase you'd expect from a 2-into-1 system while retaining the clean classic lines of 2-into-2 pipes.Softail: 18-20(NU)FLDE Deluxe 18-21 FXLR/S Low rider 18-21(NU)FLSL Slim 18-20(NU)FXBB Street Bob
