And that’s what our new Milwaukee Eight H-D Baggers head pipes do. For the 2017-2018 H-D Milwaukee Eight, we modified our famous Cobra 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 18mm bungs up near the heads, allowing the use of wideband oxygen sensors. Perfect for use with the new Harley-Davidson auto tuner. Most aftermarket mufflers designed to fit the stock head pipes should fit the Cobra Pro Chamber head pipes.
Right side muffler requires a 2 1/2-inch inlet.
