Catalytic Converter Removal 2017 Road King Special no cutting no welding.

[@jofknoll]

i've watched a few cat removals yours was the quickest and easiest i have seen

[@paultipton6939]

Thanks brother glad to help

[@americanland878]

Thanks Paul you been very helpful on this matter. You have the best way I've seen so far on getting the cc out of the header.

[@barryleimkuehler9531]

oh heck yah ! and to use a cylinder bore for the inside is genius !

[@ogles824]

I just wondered if an old school set of drag pipes or an aftermarket exhaust designed for pre cat bikes would fit these newer models. To me that would be the way to go.

[@Cromagnon4]

I saw another video where the guy simply pulled off the muffler and got down on the floor and did the same thing. He didn’t have to remove the header. Took him half the time as you see here. Header removal is pain.

[@seniorp9444]

Yeah I’ve seen the same videos. I don’t see the advantage of removing the header.

[@morrissilverstein4955]

That's how I did it. Ran the same. Cooler? Probably. And had a throatier sound.

[@johnh282]

You are a badass thanks for the videos!!!!!!🇺🇸🫡

[@davidmcdaniel8053]

Awesome removal Paul, thanks.

[@ramezy04]

great vid!

[@morrisdennis]

Its amazing the engine can even run with a cat😮

[@marka3870]

Great video. I was thinking of doing this to my 2014. Any issue with this procedure? Does it mess up the computer? Any warning lights? And will I need a retune? Thank again.

[@paultipton6939]

Mine is a Milwaukee 8 engine. Your configuration is a little different. I had to retune. Engine will run cooler after. More airflow.

[@morrisdennis]

My thinking exactly

[@billflixtone6684]

If you had to do it again, would you consider doing it with header mounted on bike?

[@paultipton6939]

I would but I was changing the cam so I had to take the head pipe off anyway but absolutely.

[@philblock]

How's it run afterwards?

[@levialston518]

From all the videos I've seen about removing the cat you have all the exhaust flowing straight and the left side tube is smaller couldn't you weld in a divider to help direct flow

[@steverodriguez7386]

Hey can i put it on a jack an drill it out or do i need to take it off ..??

[@paultipton6939]

Jack it up and do it in place. All good

[@byront243]

Hey Paul. Thanx for sharing your vid. It’s quick and to the point. That’s always appreciated. Just a couple of quick questions for you. Does this “trip” the O2 sensor at all and did you have to retune the engine for the air/fuel? Thanx much for your time, Paul. Byron, 2020 Roadglide Special

[@paultipton6939]

I did tune it when I was done but I changed a lot of stuff when I had it apart. Cam oil pump lifters push rods and intake. The sensors should not be affected they are just taking a reading. I don’t think you would have to but I’m not 100% sure.

[@byront243]

@@paultipton6939 Thanx for the quick reply. I appreciate you. Have a great weekend!

[@inthegarage.withalvaro.1344]

Great video, I’m going to try it. Thanks.

[@paultipton6939]

You do not need to take the header off to do the removal. Just an FYI

[@inked4011]

@@paultipton6939 if you do it this way, how do you recommend getting all the metal out?

[@paultipton6939]

@@inked4011 shop vac or throttle it out the exhaust would push it out.

[@henriliu9851]

how intelligent and efficient, i will do yr way

[@ryanyurkovich8516]

Hey man you have an after video for how it sounds and did you have to get a tune after as well

[@joehansen4889]

You don't even have to take your pipes off.

[@Angerot]

Colter Wall for the win.

[@paulrevere4326]

Did you feel a loss of back pressure power after you put it all back together?

[@paultipton6939]

Sorry I just looked at this. I did loose a little bit of back pressure but mainly because I have 4” pipes. I am going to do a top end change in February and most likely go to a 2 in 1 exhaust that will help.

[@zeeksepulveda7205]

You can do this while the header is still on right?

[@paultipton6939]

Absolutely

[@LeJeansJewelers]

if i remove the Cat do i need a tuner to handle the change? I am using the SE tuner on a 131 kit, Thanks

[@paultipton6939]

I didnt change anything with my tune. It just runs cooler.

[@Scoobydue420]

@@paultipton6939 well, than you must not know the tune of your bike. If you remove the cat, the comp MUST be reflashed. I work @sheldons Harley in Massachusetts, bike mechanic for 20 urs, and sadly, you are wrong. Good luck with your bike in the long run…..

[@edwingamayon5076]

Thanks for the video sir, did you have to get a tuner after?

[@paultipton6939]

I already had a tuner but I dont think you would need to retune. It cooled the engine quite a bit.

[@fastone136]

i took my dremmel and cut open the pipe on the side.where cat was located.just a window size hole and pulled out the cat.i had spare header in my cellar.2019 flhx.after the cat was out.2minutes.i took and got the piece welded back on.

[@henriliu9851]

Hi Paul, I am about to do the same way you get rid of the cat, one question, what is the capacity(amp/hour) do I need to drive the drill? I need to buy a hand set as well as the drill bit, tks.

[@paultipton6939]

I just used a 20 volt cordless

[@tedbush1072]

Did it increase the volume at all after removing the cat? If not, how did it change the tone of the exhaust? What slip-ons are you using? Thanks

[@paultipton6939]

I have vance and hines 4” slip ons. The bike runs cooler and it sounds sweet. Thinking about going with a smaller pipe. I have a 468 zippers cam and I upgraded the oil pump tappets and tappet sleeves. Im happy with its performance.

[@markmackinnon4936]

I'd like to see the drill bit you used please

[@paultipton6939]

I just used a 7/8 paddle bit. With an extension.

[@WORKHARDRIDEHARDER_]

Do you have or can you make a video showing the sound difference with the cat removed? Been thinking about doing this to my 17 Ultra Limited.

[@paultipton6939]

I will see what I have. If nothing else I’ll record it now and send it to you

[@stephenwilliams1824]

But is it legal in the US?

[@paultipton6939]

Guys running straight pipes everywhere. Maybe in Cali. Need to check your local laws.

[@stephenwilliams1824]

Besides linked speed cameras this side of the pond, new decibel monitor/camera systems are being introduced.

[@f.andrewmeunier5440]

I have a 2014 ultra classic. Canadian model. Do all 103 engine exhausts have cats on them? Does the bike have to be flashed again or does the bike work fine with it removed?

[@paultipton6939]

I’m not sure if they have catalytic converter’s in a Canadian bike or not you could call Harley and find out I’m not the expert I just pulled the cat out because I wanted to move more air. I did get a new tune for the bike because I ended up changing the cam I put a new intake on it and some other changes so I did need to put a new map on the bike I don’t think just taking the cat out would effectt the bike that much really but I would check with you local dealer.

[@kewintaylor7056]

Thats cat make engine hotter...but good for purify the hydrocarbon...well... Most ppl remove it ...🤨🤔

[@FrensTimmerpens]

I have a Road King Special 107 since 2 days. Compare ro my former HD Sport Glide ‘21 i do mis some power. I had the pipes of and there comes out a lot of coal…?! Maybe the Cat is full of shit. After removal of it you have to let the bike adjust at the dyno….tough?

[@paultipton6939]

I noticed my bike runs cooler. I don’t know if it added any performance.

[@imapiledriver2462]

wat about the o2 sensors

[@paultipton6939]

Did not change

[@fernandoleija2818]

Is it the same on a 2018 ultra limited

[@paultipton6939]

Any stock Milwaukee eight head pipe it will be the same

[@PeteyPablo408]

What's that tool you used

[@paultipton6939]

Just a drill with a paddle bit and extension. Cleaned it up with a cylinder hone but not necessary .

[@PeteyPablo408]

@@paultipton6939 Thanks for your reply what size Paddle drill bit and hone tool stones 2inch or 3 inch or smaller?

[@theyco60]

Does the computer know the cat is gone?

[@paultipton6939]

I dont think it matters.

[@americanland878]

What's your thoughts on using a hole saw in the inside of the pipe? And would NAPA have a cylinder hone tool?

[@paultipton6939]

Holesaw’s not gonna fit and it’s not deep enough I used a paddle bit I just sacrificed it. Use like a inch and a half paddle bit for wood it went through and eventually it knocked the cat loose and I just pulled it out with a pair of pliers. Those honing tools are everywhere or you can find them at Walmart probably advanced auto and that’s if you’d want to get it really smooth I don’t think it’s that necessary I think taking a piece of sandpaper around a piece of PVC or something and just getting a rough edges off it’s gonna blow it out the tail pipe anyway if it comes loose so I wouldn’t sweat it.

[@americanland878]

@@paultipton6939 thanks appreciate it.

[@burbman56]

A sanding drum on a drill extension works. So does a rotary wire brush on a the same extension. Available at Lowes or Home Depot. $10.

[@haroldwiser2641]

Thanks for the video. When I get back down to Florida the cat in my 16 ultra is toast!!
