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.
Product Note: Does not fit stock mufflers. Only fits aftermarket mufflers for Milwaukee Eight models.

I received the head pipes today very fast shipping. The install was very straight forward with good directions. The quality of the pipes and heat shields is very nice. The Cobra pipes fitment was perfect very little adjustments needed. Now the sound was exceptional. My 2020 Road glide Special has the new Harley extreme wedge air cleaner and I put the Vance and Hines Torquer 450 slip ons and used the DynoJet power Vision 4 to flash for the new system. These upgrades literally transformed my bike from having asthma to stage 3 breathing what a difference. This was my first experience ordering from Parts Giant and I'am very impressed with their way of doing business. I won't hesitate to buy from them again and they had the best price for the Cobra pipes. I know these upgrades can be pricey but if you live in a state where you still have your freedom to make these upgrades it is worth the performance gains and your bike will run so much better. If your someone who rides a lot it is worth considering. I make suggestions you make decisions. Check Cobra out.

Pipes were easy to install, sounds great with my magnaflow exhaust, it's not to loud just right, they need to describe the pro chamber. Once I received them it made sense.
By John S. on Verified Purchaser
Fit, finish, and install instructions were awesome. Fast shipping. They look and perform extremely well. Our overwhelming heat problem from the exhaust is gone. I would highly recommend to any M8 owners. The 909 slip on's have the perfect sound and look. Great performance upgrade. Definitely an increase in torqe and HP. Went one step further and added an S&S intake manifold and K&N filter. Absolutely pleased

The Cobra headers eliminated the hot spot on my right leg. They also sound awesome with my reinhart racing slip-ons. Very easy installation. I recommend these pipes for anyone with a Freewheeler to eliminate heat. Very satisfied! Good job guys!

Excellent
By Mooch B. on Verified Purchaser
Giving many and large stars for the ease in which these header pipes were to install. The instructions were easy to follow step by step. Every bend was exact. No force was necessary during install. The quality material used is outstanding. The end result was like Michelangelo built these to perfection. The sound and looks are exactly what I was wanting. Thanks Cobra for your expertise in design and quality workmanship.

Recently had the cam upgraded and decided to do so with the head pipes. Already had Neighbor Hater slip-on’s. Easy install, other than having an issue with the right output, the slip-on did not fit. Had to grind the output to install the slip-on. Other than that install went well. Wouldn’t you know, that was the last step of the install. Pipes sound great and look even better. Wish I had installed much sooner.
By BUDDY K. on Verified Purchaser
These pipes went on very easy on my 18 Street Glide Special. Really like the sound too.
By Ian A. on Verified Purchaser
Built well, straight forward to install. Great sound

Great sound, look terrific, easy to install!
By Derrick P. on Verified Purchaser
Makes my Cobra Neighbor Haters louder and on point. Love the sound and performance.
By James & Deborah G. on Verified Purchaser
Very easy to install. The looks on the bike is way better than the pictures they have on the info page to looked at. These pipes are bad for sure. Great sound and way cooler than stock pipes. You can't go wrong with the Cobras on your bike.
By DWC18king on
Have these head pipes paired with the Cobra Neighbor Haters. The sound and performance of the pair is great. Easy to install for anyone that can turn a wrench.

Parts Giant is the Amazon Prime of motorcycle parts in my book. I ordered this Corbra Pro Chamber Head Pipe and the next day it was at my front door. Install was a breeze and the price was the best that I can find. I also bought a set of black 909 slip ons with a V&H Fp3 tuner. Awesome prices and super fast delivery. My 2019 RoadKing looks great and sounds awesome.

Answer QuestionNo, there's no need to purchase torque cones for these, or any other set of headers made by Cobra. They come ready to bolt onto any machine you select from our fit guide with no need to buy any additional fitting components.
By Steven C.
Answer QuestionYes, these pipes would work with the Cobra 909 slip-on's.

Answer QuestionThat would depend on what else you have done to your bike. If stock, most likely not necessary. If you have an intake or slip-ons etc, then I would suggest adding a tuner as well.
By Strong
Answer QuestionSo long as the mufflers work with the OEM head pipes, then you won't have any problems fitting them to these awesome Cobra headers!
By Howard H.
Answer QuestionYes, if you were to select the FLHTCUTG Tri Glide Ultra Cobra Pro Chamber Head Pipes from our fit guide, you'd receive the correct headers to fit your machine. The 909 mufflers from Cobra will certainly work with the headers as those are designed to fit the stock headers. Enjoy that extra volume!
By rick
Answer QuestionThis particular exhaust comes with 12mm oxygen sensor bungs. You need the Cobra Pro Chamber Dual Bung Head Pipes as those pipes come with 18mm bungs that'll fit the Thundermax ECM's oxygen sensors.
By Anon.
Answer QuestionWith a properly tuned engine, intake, Neighbor Hater mufflers and Pro Chamber head pipes on the new M8 engines, you can see power gains around 8-10 horse and up to 12 Ft lbs of torque when properly tuned. I would highly suggest a Cobra Power Pro Black or Vance and Hines FP3 fuel tuner to get the mode power output possible from the new setup.
By Buzz
Answer QuestionThese pipes are not compatible with any of the HD pipes for M8 models due to the right side slip on design. There is a support near the PowerPort that will not accept HD stock design for the factory or Screaming Eagle slip-ons. You would have to go with an aftermarket muffler such as the Cobra Neighbor Haters or any other slip-ons listed for 2017-2019 touring.
By Brad
Answer QuestionThe Cobra Pro chamber head pipes have a larger diameter junction at right slip-on for the 2017-2019 Harley Davidson Touring models. Just keep in mind these headers only work with aftermarket slip-ons. They will not fit factory HD slip-ons due to a clearance issue on the original mufflers design.
By Anon.
The stock crossover pipe is flattened out, does not flow well .I wanted to know if a new crossover pipe was included with the new header pipe.
Answer QuestionThis header will indeed include a new Cobra designed crossover pipe that is made of round exhaust tubing.
By Anon.
Answer QuestionThis header will fit with any aftermarket slip-ons that are designed to fit factory head pipes. The original HD pipes have a bracket on the right side that will not work with the power chambers design. This is the only reason you would need aftermarket slip ons to work with these head pipes. The S&S MK45 would fit just fine.
By Anon.
Answer QuestionOnce you select your 2017 Harley Davidson FLHTK Electra Glide Ultra Limited there will be a drop down menu option for black or chrome finish. We can accept phone orders Monday-Friday 10-6 PM EST at 888-575-6570 or 24 hours a day online at www.Partsgiant.com
By Tommy
Answer QuestionThis will work much like a 2:1 system by providing better scavenging over the stock header. The PowerPort collector has been enlarged to become a pulse chamber that accelerates exhaust scavenging. Keep in mind, you can only use these headpipes with aftermarket slip ons designed to fit M8 touring models. These headpipes will not work in combination with stock Harley-Davidson mufflers due to the right muffler slip design.
By Jamie
Answer QuestionSo long as the Race Pro slip-ons you have are designed to fit Milwaukee 8 touring bikes, you should have no problem fitting them to these headers. It's only when users attempt to fit stock mufflers, or mufflers for Twin Cam Touring models that they run into issues. Basically, so long as the mufflers are the correct aftermarket items for the model you select from our fit guide, you should have no problem fitting them to your machine.
By Jake
Answer QuestionCobra's Pro Chamber head pipes will fit any aftermarket muffler for any of the machines you select from our fit guide, including their Neighbor Haters. So long as you have one of the machines listed in our fit guide, you won't have any problems adding these headers to your bike along with the Neighbor Hater slip-on mufflers.
