FLHTCU - Electra Glide Ultra Classic (17-23) Baggers®

Pro Chamber Head Pipes with Dual Bungs

This product is not legal for street use on an emissions-controlled vehicle. It may be used on dedicated competition or pre-pollution-controlled vehicles only
NOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY POLLUTION CONTROLLED MOTOR VEHICLE. THE SALE, USE, OR INSTALLATION OF THIS PRODUCT MAY ALSO BE ILLEGAL NATIONWIDE UNDER THE FEDERAL CLEAN AIR ACT (42 U.S.C.§ 7522(A)(3)). 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.

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.

Emissions Notice

The state of California considers aftermarket exhaust systems to be legal replacement parts for non-catalyst equipped motorcycles and/or if slip-on mufflers are installed downstream of the OEM catalysts.

California does not allow the use of aftermarket systems that remove original equipment catalysts, (except for racing use only) unless the Air Resources Board has issued an Executive Order for that system.

For California riders we offer Air Resources Board approved Fi2000 R ARB units. (ARB E.O. No. D-633-1). All other Fi2000 models are not legal for street use in California.
