Description
- For the Milwaukee Eight motor, Cobra modified their PowerPort by enlarging it to become a pulse chamber that accelerates exhaust scavenging to produce the kind of power riders expect
- The round shape, bulging from between the heat shields gives a clue to the real power potential it offers
- Includes 18mm bungs up near the heads, allowing the use of wideband oxygen sensors; Perfect for use with the new Harley-Davidson auto tuner
- Stock H-D mufflers will not work with this head pipe because of the stock muffler’s internal construction. Most aftermarket mufflers will fit

These new dual bung pro chamber headpipes from Cobra are awesome, I’m a total Harley fan and these pipes really deliver with the dual bungs for oxygen sensors so you can use the auto tuner, the pulse chamber gives great power and the bulging shape between the heat shields looks sick, gave it 5 stars because performance is awesome and it looks badass plus shipping was good too with no damage, definitely recommend if you’re upgrading your Milwaukee Eight and want more power with a sick look since Cobra makes good stuff, overall amazing headpipes just what I was looking for.

These dual bung headpipes from Cobra are fantastic, they really wake up my Milwaukee Eight engine with improved throttle response, acceleration, and a mean rumble. I highly recommend them to anyone looking for more power from their Milwaukee Eight.

I bought the dual bung pro chamber headpipes by cobra which have some neat features and look cool but while installation was easy and it sounds good I’m not totally blown away by the performance so overall it’s a decent product that looks nice and sounds good but there’s probably better options out there if speed is your main goal.

The Dual Bung Pro Chamber Headpipes boast some neat features but the chrome was prone to scratches and installation was tougher than I expected. The pulse chamber does deliver on the promise of more power and torque, and the O2 sensor bungs are handy, but for the high price I’d probably try some other options first that match the performance but have better quality.
