- DO You NEED to Tune Harley Davidson Motorcycle with Slip On Exhaust!?? This question comes up a lot when adding a slip on exhaust to your Harley Davidson Motorcycle. There can be a lot of information out there with all the different products, companies, and brands, it can be tough to get to the right answer.
Drop you comments down there and let me know your experiences with tuning and slip ons, is it needed??

I have a 2023 Street Bob with Cobra NH and I did not need a tune, the bike runs great with no issues, if you do a full exhaust you will need a tune.
Yeah mine runs fine too
Were these significantly better sounding and louder then stock?
Hi my friend i have a harley street bob 114 2021 i take both slip on buffles out so is make more loud i will need a tune up,thanksssss
I have the same bike with the same exhaust and my bike is running fine
@@felixprieto9270 le quitaste los mufflers ? Y corre bien ?
My first upgrade on any bike is aways the power vision . It's probably one of the best ones on the market being a comes full of preloaded Tunes. And that is a diagnostic tool. And real-time gauges and data logging.
I've also heard that's a great one
@@TheMotoJawn I was just curious if you ever did any merchandise with your Channel logo
In the event that the entire exhaust system and air filter are modified, a retune is indeed essential. However, if only the slip-ons are modified, a retune is not required.
Thanks for explaining and sharing your experiences. What you said in the video is indeed a general consensus and I cannot agree more. Tuner is needed when BOTH high flow air intake AND full pipe system are put onto the bike, and it makes "these three things" a Stage 1 Upgrade.
But, I have heard another statement and wondered if it is true : The first thing you do before getting your slip-ons is a tuner cuz the tuner will cool your bike down and make it run better. This confuses me.
Adding a tuner to a 100% stock bike is like telling the ECM the parameters that she already knew. Why do I need a tuner on a 100% stock Harley?
I'm no mechanic but I wouldn't see the need to tune a totally stock set up
2022 Low Rider ST with slip on pipes, my dealer said yes, a tuner was used. If I want my warranty to be all good, I need to follow the recommended dealer instructions 😊
Depends on the dealer, when I talked to the manager when I bought my bike, he said don't worry about it. Any warranty related issues will not become a problem for not having a tune. The parts department obviously tried selling one.
Been meaning to get back with you. I've put on the cobra NH, an saddleman explorer seat, cobra removable sissy bar, and Memphis shades road warrior w/ 11' windshield.
I can say the slip ons will not affect the bike to any measurable degree. Like you said. However, I've been told multiple times from the harley bros around me that I should get a tune anyway. Haven't done it because I don't need it tbh. Love your content man.
Thanks man! All great modifications 👍
the stock 114 air cleaner is already a high flow set up and the motor is set to see 14-15 afr, while cruising, in stock form.
I have a 2021 Street Glide and i added Cobra Neighbor Haters and was told by Harley that i do not need a tune unless i am changing the headers also. If im doing a slip on and an air cleaner you should retune but not just mufflers, the stock headers have the CAT and very restrictive. I went with full cobra true duals with the neighbor haters and high flow SE filter so yes, i needed a tune.
Then why keep clicking snake bite SSSSSSSSS 🐍 🐍 🐍 🐍
Yes. The harley ECM can handle 10% of change of air @ fuel. After that you will need one. Most likely it will be running to rich.
👍👍👍
I have a question to this topic: I recently got a 2020 Sportster Iron 883, and found a good deal on a set of '07 STOCK Softail mufflers, which do NOT have cats like my stock mufflers do. They sound great, bike still runs great (although I can smell it's a little leaner), but my question is, is running the older mufflers with no cats (baffles are still in place and complete) going to hurt my bike? It has not been tuned, and it is otherwise completely stock.
Thanks for the video. I just bought a new “23” low rider s with 30 miles on it. I ordered an SPC laneplitter 2to1 exhaust and waiting for it to come in. I am ordering a new air filter for my intake and was wondering what a good choice would be. Also is it recommended that I have the bike tuned after replacing the exhaust & air filter? Good day bikers…
I put on Rinehart slip-on's on my bike and runs perfect on my 22 Street Bob. Was told by my dealer that I did not need to flash the ECM.
I have a 2022 FXLRS 117 with Tab slip ons medium baffles no issues what so ever besides it sound like a Harley now! From what I’ve been told the bike will adjust up to 10% parameters that’s just for higher elevations different environment climates so slip on should adjust out
Those tab sound really good 👍
@@TheMotoJawn I like them , I would recommend them . I think the medium baffles have a bit of growl to them sound better than zombie baffles in IMO
Hey again fellow Philly dweller. I put V & H Eliminator no baffle slip-ons on my 20 Street Bob 107 and it may be my imagination but it seems to have more pep. Not mine but the 114 like yours come with a heavy breather intake so are tuned for that intake already
Probably makes a little difference
@TheMotoJawn Well my Street Bob is now gone, traded in for a 23 Low Rider S. Stock pipes are very quiet. Will let you know how it is riding around Philly. Enjoyed the ride from Stars and Stripes but too soon for a real opinion. Went in to look at a used bike and they talked me into going new.
I literally just asked all these questions of my dealer. On a brand new 23 breakout. Their answer is that the stock muffler slip on have catalytic converters built-in. So removing them would require a tune. But on top of that you can potentially run it without a tune but you will get more pop and bang exhaust without a tune supposedly.
I ran my m8 with slip ons and 2 to 1 no tune runs great perfectly fine
I was told, The stock air cleaner IS a high airflow intake on the 2024 street Bob. Therefore, if you put the slip ons on, you have to tune the bike....... Is this wrong?
Ecm is already set up for intake it comes with. Slip ons won't make much difference in needing to tune
2024 street bob … removing factor mufflers with cats in them and installing cobra NH will not need a tune ?
No should be fine. Mine was
I put Vance and Hines mini grenades on my old 22 street Bob and it ran great. I now have a 23 Lowrider st and the local Harley dealer told me I need a tune even if I just change my mufflers ! Yet another bike shop said no. Guess I’ll find out for myself
Yes you do. My first Sportster had V&H pipes. After riding it for 500 miles, I traded it in on a Sportster with a Stage 1. Way better. The first bike ran like crap.
Did it have anything else done to it? Most people never have a problem with just slip ons.
@@TheMotoJawnstory time…..after not riding for 35 years, I needed to get back into it. So at age 72, I bought a 2012 xl1200 custom. I got it from Brandywine, and it only had 1906 miles on it. It was mid January so the weather sucked, and I didn’t test ride it. What could be wrong with a bike with only 1906 miles on it? I had worked at HD in York back in 1982. This was when HD bought the company back from AMF. Back then, HD only made a handful of models. Everything was made in York except for the engines and trans units. That’s where I came in contact with the Sportster. Always wanted one. It just fit. Anyway, I finally got to ride the bike in March of 22. It hadVance & Hines pipes on it. Not slip ons. The bike ran well, but ran rough. It backfired a bit when down shifting. I pulled the plugs, but they were fine. There wasn’t a tuner installed. So after 500 miles, I decided to go test ride another Sportster. I found a 2014 xl1200ca custom at Freedom Valley. I rode it and immediately knew the difference. The 2014 had Python pipes, a big air cleaner, and a tuner in it. A full Stage 1. It was peppier, smoother, and way nicer looking. Done deal. Bought it. Also found out that the 2012 sumped the oil. So to be honest, you are probably right. If they were just slip ons, then a tuner might not be necessary. But I am tickled with my newer Sportster. End of story.
@@phildiegidio4658 If I remember correctly, 2014 was the first year the sportster got O2 sensors. Those O2 sensors give the bike the ability to make its own minor adjustments depending on air flow. It can run the bike richer or leaner on its own by about 10%. Pre 2014, the sportster had to rely on the static tune in the ecm. So even a small change would put it out of whack. So long story short, if you have O2 sensors you should be fine throwing on some slip ons without a tune. If you don’t have O2 sensors, then you should get a tune with any performance upgrade.
Full exhaust a Sportster 1200 needs a tune
My tab performance with zombie baffle sounds great without a tuner
I've heard them they do sound good
Adding a stage1 upgrade and can for 2022 HD FXLRS, wow
Had an idea for a video for you today. Revzilla has a store near you right? Is it huge? Worth a video? Maybe they would let you film? Maybe get a little sponsorship ?
I like the idea on a sponsorship lol. But yeah the actual store isn't really that large. Maybe not enough to film
I have the exact same bike as you, except mine is in Fastback Blue. And with the Vance & Hines slip ons it runs great. I did buy a V&H FP4 tuner with all the Revzilla points from my R6 parts, but have not tuned the HD 114 ECM with it yet. Waiting till I get past 5k to give it a try💯✔️🏍️
That's awesome I'll be curious to get your feedback once you do it
@@TheMotoJawn ~ Thnx, I’ll let you know. Just hesitant as from everything I read, as soon as you plug in a V&H tuner to remap the ECM…it voids the warranty. So just waiting a while till it’s broken in for a year or so.
I would think any change to the intake or exhaust would need a tune. Different air flow occurs whenever you change intake or exhaust. Just a thought.
Intake definitely. But just slip on exhaust seems to not create enough difference
Did adding the tune and the air filter with the slip ons change the exhaust sound at all? Also, I wanted to go with V&H Short Shots but the dealer said it would need a tune since it was a full exhaust so opted for the Twin Slash. They’re not as loud as I expected.
I never had the tune with just slip ons
The stock ECM can add or subtract up too 10% more or less fuel to keep the air fuel mix ratio correct. That it's job.. So no you don't need a tuner
Seems to be accurate from what I've seen
The European market require 4 o2 sensors ( 2 on headers and 2 on mufflers) Can not get the slip ons with housing on o2 sensor, so tune is required when changing mufflers. Stock Airfilter is high-flo so no need to be changed. For now, changing slip ons you will lost low end torque, gain more hp and more more sounds. To not lost torque you will need back pressure like on stock mufflers. Also Tune , changing slip ons in Europe may void the warranty. USA market is still fine, changing only slip ons will not afffect warranty on the bike, because, there is no o2 sensors.
I am doing a full vans & Hines exhaust system on my 2023 breakout. Do I need to tune?
Probably would be best to eventually tune it with a full exhaust
I have 2019 hd 48, i'm putting a slip on sharkroad with stock air filter, After running for 6mnths 1000km my O2 sensors front and back were damaged, may it be the cause? Or maybe because I overfill the oil?
Damaged how?
@@TheMotoJawn error code p0151 and p0131, idling is rough.
Love this bike !🖤❤️
💯💯💯💯
I’m going to be putting the Bassani Radial Sweepers on my stock 2020 Iron 1200. Will I be ok w/o a tune if I keep the intake stock
I would guess that an electronic fuel injection could adjust the fuel mixture settings automatically, then again, I could be wrong.
I think that seems to be the case. They can handle a slight variance if needed
Welp according to Doc Harley, you wont need a tune with just slip-ons, besides i ran my 2021 bob around all year without baffles and cats and Thunder Torque Inserts. The 114 ran strong, and now run S&S slash cut slip-ons on the factory tune.
I still haven't tuned my 2 to 1 and runs fine
I'm struggling just to get slip ons on my 2022 street bob 114 as the UK versions have 4 O2 sensors, 2 in the front 2 in the back, and there literally no info to sort this on the UK market, I'm eventually going for a stage one but saving up so stuck with the sewing machine sound
I just got a iron 1200 from a dealer. It came with cobra 3" rpt slip ons. Stock filter. I get decel pop and shaking when hard acceleration and lots of shaking on idol, They say it's normal for the shaking. Long story short they say I don't need a tune for the popping.
bro ... they are wrong ... decel popping at hard acceleration is not right , trust me it needs to be set up ! The cobra 3 have less back pressure .
I've heard the same thing, about no tune required, however on HD's website they say a tuner is required for the Screemin' Eagle Street Cannon slip-ons. So much contradictory info out there, kinda stinks.
Yeah I feel like that's gotta be an upsell tactic. I find it hard to believe SE slip on would be any higher performing than the other brands out there to really need it
@@TheMotoJawn Totally agree! An easy way to sell you something else.
I don’t see really how it’s going to change at all if the converter is in the header because without changing out converter it can really escape more might can make more in but their again the u can always put more of anything in but if it’s going out the same is it really going in more
I just got a 23 Lowrider S, which slip ons sound the best? Low rumble thumping sound? Thanks in advance.
I had the cobra neighbor haters and thought they were decent
Thank you sir! You are a scholar and a gentleman.
@@andrewwilliamgomez I have a full video on them as well for some sound clips
I have a lowrider s and I put a slip exhaust on it and I feel like I lost a tad tad bit of horsepower. Idk.
Yes , tune , absolutely , factory tunes too lean. Especially when adding slip-ons . Just a simple tune is like night n day . Iv done this with my 117 m8 using a Maximus tuner.
Do you if the cats are in the OEM mufflers ?
Cool outro music 👍
I'm having the problem where I Installed a Hi-flow Ventilator air cleaner that comes stock on a Street Glide and now my bike is running a bit hotter It make no sence to me because I'm running the stock mufflers and now my cooling fans are comming on all the time soon as I stop the bike till I start rolling again. It wasn't like that with the restrictive stock 114 air cleaner. The instructions say that ECM must be recalibrated. BTW now it sounds amazing even with the stock mufflers.
More air = more combustion = more heat. You probably want to get a tune to recalibrate your ECU.
I have a 2023 street bob from which I removed the cats from the stock exhaust. I left that cardboard, honeycomb looking baffle in the back but still lost significant amount of torque. I’m wondering if I should get it tuned for 2 reasons: to get that torque back, and to not harm the motor if that in fact can cause harm. Guess I should’ve thought it threw before I started cutting. But bike sounds great 😆
😂😂 just go ahead and get that new full system!
Switched from the OEM heavy breather to a SE Ventilator. Both are high flow. Can I get away with modest slip-on?
it would be a safe bet to tune after a new intake and slip ons
great info
In simple terms lol I'm sure it could be explained in greater detail
Could you please paint your front fairing?
Hello Moto Jawn. I wonder if you can Help me. I have a 2021 M8 Softail Slim, And I live in Spain. at the moment the bike is Stock. I have 4 Sensors 2 0n the headers, and 2 on the slip on exhaust. I have tried to get information from H-D about slip on for my Bike without tuning. and have had no luck. Can you help me. regards Bob
M8 with just slip ons shouldn't need a tune. Same as my set up and it's fine
@@TheMotoJawn Slipons dont hav sensor in them
My slips on do from H-D, also catalyst in each one. It seems it must be a Europe problem. Thank you for your time. Regards Bob
What about with no slip ons. Straight pipe
Straight from the header?
@@TheMotoJawn yeah just headers
Hi, I bought a 2022 FXBBS and I choose the Neighbours haters to put in. The problem is I live in Argentina and we have the fucking Euro 5 specification, so the bike has the lambda in the oem slip on... So, we need to add a FP4 to tune the ECM. If I do not put the FP4, I will see the "Check Engine" 24/7 in the gauge. All the "internationals" Harleys are made to get the Euro 5, so they need a FP4 or similar...!!!
If you’re installing slip ons without baffles (baffles removed) you most likely will in most cases.
Have a 2023 Softail Low Rider 2 117. Cat is IN slip on. neighbor haters like many slip ons dont have a cat in them. Anyone got any experience with this?
I have the neighbors haters on my M8 like them so far. No problems. Decent rumble
@@TheMotoJawn I saw that; nice! Mine has the 117 so I hope I get same good results. Good job on this video btw.
My 2022 FXLRS 117 has medium baffle no Cat Tabs only with no issues or decel issues at all
@@jamesduke7965 I get decal pop pretty often.
my bike ran like crap with just slip on's , put a fp3 fuel pack fixed the problem!!
Interesting. Mine have aways been good without
@@TheMotoJawn that is interesting because mine is a 2021 iron 1200 it was popping and sputtering.
I have a 2021 iron 1200. Put V&H slip ons on and it runs like crap. Have a FP3 on the way. Hope it helps. I will say that the first attempt to tighten my slip ons, they were leaking at the clamp.
@jeeper911 My iron 883 has been popping when releasing the gas and changing gears, torque was less and now its been loosing power when i have a passenger, when riding solo it works fine. Im blaming the slipons
Endless 4 minutes to give a simple answer...
You can tune a stock bike for a “peppy” ride.
To me tuning a bike for slip ons is a waste of money.
Now it costs hundreds of dollars to change the jets.
Slip-ons need a tune? Absolutely not. Wait until the cam and full exhaust. Waste of $$$ with slip-ons. Also, NEVER ever use a Screaming Eagle tuner. Total waste of money. Yea, it maintains a warranty but it does no good. Screaming Eagle though quality parts are crappy parts in terms of performance.
The old your engine needs back pressure or you’ll lose torque myth still lives.
I just removed my mufflers of my sportster and I Love the sound, but I am worried if I Need to tune now … help me please?
Btw: its a sportster 1200 - 2018
I dont pretend to change the air intake (original)
If you just change the muffler then no you shouldn't need a tune
@@TheMotoJawn its like a straight pipe now … so you think its okay to run ?
NO NO NO NO NEVER! NO.
I have vanson hines slip on on a ultra classic If it has not been tuned would that make it stop idling at stop light sometimes
4 minutes before you even answer the question!!
4 minutes of bs .. Jesus christ..
