Cobra Pro Chamber Dual Bung Head Pipes


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 Cobra's head pipes do. For the H-D Milwaukee Eight engine, Cobra modified the PowerPort by enlarging it to become a pulse chamber that accelerates exhaust scavenging. This design produces 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.

Great product

Great product for the price.


Great value, great look and performance

By   on  Verified Purchaser

I paired these headers up with the cobra 909 upper cut slip on and an Arlen Ness air cleaner, the result is fantastic. Great sound when you roll on it, but quite enough to easily hear the stereo while cruising. I have more power and torque along with better fuel mileage. I highly recommend these headers. I wish I could post a picture hear cause the chrome is flawless and they look great.


Pro Chamber on 2019 Street Glide Special

I literally had these pipe delivered and installed on my bike less than 24 hours after I placed the order. As far as the product, fitment was right on and heat shields easy to install. Just what I was looking for. Sound great and price was right.

Fits perfect. Directions are easy to follow. Sounds mean with my Cobra neighbor haters slip ons. Even with the baffle in. Sounds like a Harley now.


Where did my bung plug go?

By   on  Verified Purchaser

These pipes make my Road King sound great. I have read reviews that don't give these the credit they deserve but friends I ride with, don't want to ride behind me because combined with the Neighbor Hater tips, the sound is really deep and powerful. The only reason I didn't rate this a five is because the factory didn't tighten the bung plugs in the pipes so one of them fell out. It cost me 24.00 to replace the bung plug and wait for the plug to arrive. Word of warning, make sure you tighten the bung plugs and a little thread locker wouldn't hurt.
