Sound Test - with and without dB killer S&S SuperStreet 2-1 exhaust (non-cat) Lowrider S stage II

- เผยแพร่เมื่อ 23 มิ.ย. 2021
- Sound test with and without dB killer installed plus removal from muffler on S&S SuperStreet 2-1 exhaust. This motorcycle is a 2020 Harley Davidson Lowrider S 114 stage 2 with an S&S 475 cam chest kit installed. The bike is tuned with a Power Vision tuner and Fuel Moto base map w/ dyno auto tune by House of Harley Davidson in Anchorage, Alaska. The result was a noticeable difference in volume as well as tone. My personal preference was without the dB killer installed. I like the louder variation but the exhaust note without it is spectacular. I hope you enjoy this comparison. Enjoy your ride!

Thanks for this vid, just fitted it to my 114 Breakout, your video helped me decide. Removed the crap 2into2 V&H 👍
Awesome video, man! Thank you for putting in the effort and sharing exactly what's needed with no BS. I'm buying a Sidewinder, but same principle, and you gave the answers I was after. Thanks again! ✌🤘
Thanks bro, I appreciate that!
Thank you
That pipe sounds great either way, I wish they made that pipe for my 02 lowrider, thanks for the demo. Enjoy that bad ass and be safe👍🇺🇸💪✌
Great vid, really helpful as I’m looking at new system at the mo
Thank you, I appreciate that. I changed it out for a Jackpot Riot pipe. If you’re interested, here is the last vid:

Neighbors probably loved that you made this video 😂
Heheh yeah man! Truthfully I have pretty awesome neighbors
Thank you great video
Sounds badass 😎
Hey a fellow Alaskan! Nice video man
Howdy! Thank man!
Yes indeed, thanks! I'm taking mine out Fo Sho! It sounds like a muscle car without the DB Killer
2021 Sport Glide with the same setup here. Used your vid as a tutorial to take mine out, so thanks for that! I notice it's actually less obnoxious with the DB killer out.. with it in it has sort of a "glass pack" reverb that I'm not a fan of. Keeping mine out too. Ride safe.
Glad I could help. And that is a spot on description about sounding like a glass pack. That’s what I thought as well. Overall, I ended up not liking that pipe much because it rubbed a lot of power unfortunately, so I swapped it out for a Fuel Moto Jackpot riot.
I cut mine in half(lengthwise) and stuck it back in. Perfect compromise.
Did the same after reading your comment. Could not be happier 👏
Definitely OUT !!! All my bikes had drag pipes installed without the baffles.... STRAIGHT PIPE !!! Gotta love it... the neighbors ??? Not so much!!! Haha yeah 😆 🤣 😅. Thanks for the review.!!!
Your neighbors loved you hahaha hell yeah brother!
“Love” is such a strong word 🤣
I really enjoyed the comparison. Shopping around for exhaust for my low rider s... I think I may have just found the solution! By the way, what foot pegs do you have installed with this build, I really like the look of them.
Thanks! Truthfully they are both great exhaust systems. But the long pipes are supposed to offer the best performance for these M8s. As soon as I have a spot available on the dyno I will post a video of the power differences between the two pipes. This is the link for the pegs. My dealer had them hanging on the wall:
www.harley-davidson.com/us/en/shop/80GRIT-Rider-Footpegs-with-Wear-Peg/p/50501382
Thanks for sharing. hard to tell on my laptop if its any louder a DB reader would help. But it definitely sounds deeper and nicer note with it out.
It sounds a little cleaner with the DB killer in, but definitely quieter. I didn’t like it because it wasn’t much louder than stock. On the other hand, it wasn’t overly obnoxious either with without the DB killer. On all it sounded OK but I didn’t run it for very long because honestly, I lost a lot of performance with this one.
I have another video where I tested this pipe against two other exhausts with the Dino sheets if you’re interested. That’s what I was getting at was that didn’t notice a difference with the DB killer in or out but the pipe itself didn’t perform well.
Nice
Omg. So much better without. 🎉🎉🎉🎉
I like it
Been waiting for a comparison of this, thanks!! I got these pipes installed on my Fat Bob a few weeks ago and am a little disappointed with the sound; a bit too high for me. Would you say removing the db reducer make the sound a lot lower and more rumbly? Sounds like it in the audio here
Absolutely. Deeper and cleaner tone and also much louder

How is it dealing with the extra "width" from the rear header being routed up front? Looks like it would be coming in on my ankle right where the floorboards are. Nice vid.
It didn’t seem to make a difference at all
Where did you get that side mount for the license plate? I've been looking everywhere for one!
Here’s a link for it from Dennis Kirk. I don’t remember where I bought it from but you can get them from JP cycles, RevZilla, etc. You need to order a mounting bracket with it but they have a autosuggestion thing that will probably tell you what you need. They make them in chrome and black. www.denniskirk.com/kuryakyn/gloss-black-nova-vertical-side-mount-license-plate-holder-3191.p4902625.prd/4902625.sku?gclid=CjwKCAjwtcCVBhA0EiwAT1fY78UnIuB0Zgb6W-VNAaetOOKRze0_2c7Lo7OIGtudeWFCVKFMj_frKhoCUUoQAvD_BwE
should give it a try without the dB killer and the baffle wrap off, of course put the baffle back once the wrap is off, sure do miss Alaska didn't have a motorcycle when I was there unfortunately, always thought there would be good riding up there
Yeah man we have a lot of fun up here for sure. I’ve moved on to a different pipe though since I made this. Working on another video. This pipe didn’t work out like I had hoped tacitly so I went with a Jackpot stainless. Love that thing.
What was dyno numbers? Did HD suggest leaving in DB killer? thx for vid
Wasn’t very good with this one. I didn’t get any differences with the DB killer in or out as far as horsepower but I don’t recall what they were because it was so long ago. I did, however, do an exhaust video of the three that I tested and if you’re want to see dyno sheets, then you can watch this video, link below. If you don’t want to watch the whole video, then the dyno sheet comparison and analysis is at the end of it. But I talk a little bit about the tuning and different experiences with each one. I still run the jackpot and I bought an RTX for my Street Glide and also for the Road Glide I just finished. Both of those bikes have 131’s, the RG 150hp/154tq. The jackpot pipes are rated for high horsepower builds. I hope this helps.

Would you recommend a tank lift for a new 2023 Low Rider ST with the fairing?
Going to be honest, I had to look that up, didn’t know it was a thing. Sounds like would help for wind buffeting which makes sense to me since most of the air buffeting a helmet comes from under the tank coming around the front tire. Let me know if it works.
Nice suggestion I’m def trying it. Do you remember which hex key you used? And is there a lock in one of the bolts where you needed a “special” hex key to remove it?
I don’t recall specifically and I no longer have that pipe. A 4 mm or 5 mm. If you are looking for a special key then you might have the California version or 50 state version. Those are welded in and from what I understand or a little more difficult to take out
@@robb907 I may have the 50 state one, bummer!
@@russelrides3218 that is a bummer because that one also has a cat in it. But I know some guys have used a die grinder to cut the screws out and then use sheet metal screws after they pull the baffle out. Don’t know what to do about the cat though I really nice exhaust that I liked a lot better is the jackpot riot. Is it more of a classic Harley sound and I perform better than the four systems that I tried. I have a video up about that with Dino sheets if you are interested in more info there
@@robb907 I’ll take a look later but I do recall seeing the three screws similar to yours. I’m guessing ones I take it off the db reducer is welded in as you mentioned, but def will be worth a shot! I’ll check your other video you mentioned.
Going to change out my V&H dresser duals to a 2 into 1 because I want to upgrade the cam. Was going to go V&H pro pipe, but after seeing your video I think I have changed my mind. I like the sound both ways but it sounds a little deeper and "thumpy" to my ears with it out. I like that S&S gives an option. thx
Check out fuel Moto‘s jackpot riot pipe. I have a video with dyno sheets a little newer than this one if you’re interested in that. The S&S pipe was too much of a power drop so I switched it

@@robb907 Doing that right now thx again for the info. I ride a 12 Road King
@@robertglancy4474 very nice. Just starting to get warm and sunny here in Anchorage. Ride safe!
@@robb907 You as well....I'm down here in Tucson AZ were getting warm here as well 102 yesterday...lol
@@robertglancy4474 good grief I hope you get out on the Windee roads with no stop lights!
Came for the vid and surprised for Park Tool
They’re handy for everything!
I came to rewatch your video to see how you removed the DB killer.
You used the same tool to take off all 3 screws.
I feel like I have the same exhaust but only 2 screws are the same. The 3rd one has a "dot" in the middle of the screw so using the same tool doesn't work.
Was yours like this as well? Or do you know what tool to use ?
All three screws were the same and came out easily on mine. Do you have the Cat version? Or it’s called 50 state legal version. If you do then that’s welded. Possibly you could drill it out? But then it’s no going back
@@robb907 thanks for your reply. I do have the 50 state legal
Ok than. Yeah that's what I was reading that ppl would drill it out . Dang I'm bummed now .
@@PackersFlip I got rid of that exhaust by the way. I went with a Jackpot riot from Fuel Moto. All problems were solved. I made a video of that with the dyno sheets
Doesn’t that kill the low end by removing it? What tuner you running on this?
That’s what I thought but tested it and found no more than one or two numbers difference which can happen without changing anything. I run the power vision.
Defiantly sounds better with it out. i dont like too loud though. I have a Cardo that i listen to tunes on. I saw a video of someone who cut the DB reducer down.
That would work. Really though, it’s not that loud being that it’s as long as it is.
@@robb907 ya ill check it out. the reducer is cheap and i can weld it back so ill cut some off and see what it does.
@@JCunningham21 I actually replaced this pipe with a Jackpot Riot. It’s a great pipe but a little louder than this Superstreet w/ the baffle out.
I like it without the baffle a tad more, both sound far better than stock though.
However don't you typically lose power by removing baffles?
Yes, but this is the dB killer, the baffle stays put. I do wonder though because as you can see the shape of this does offer more restriction. Could be a little excessive but I never tested on a dyno with it in. Since then I have gone to a Jackpot riot pipe because I did dyno test with it out and the power was low enough I didn’t see it recovering with the dB killer in and/or a tune. It was pretty low
That DB killer affects your exhaust velocity out of the pipe.. it’s sciency stuff that was explained to me by MUCH smarter folks
you loose back pressure which in turn you lose low end torque but you game HP in the top end, its a weird science if you wanted the torque back a little but you don't lose the sound you can always screw in an eyelet screw made for walls. gives you baffler back pressure with out the baffle sound. also a weird science but it works good
@@quintengonzalez1184 I found the info again.. sonic pulse, thermal pulse & exhaust gas velocity are the considerations for engineers when designing exhaust systems.. different designs affect performance differently.. not sure how one screw could change anything.. I’m no engineer so…
Do you like the db killer in or out.?
How did you get the non cat version without it saying “race only” on the side?
Interesting question. I just ordered it and it came. Would be worth a call to S&S to ask them. Maybe they started putting it on after the batch that made mine?
I just ordered the S&S Sidewinder 2/1. J&P Cycles still had both versions, but I think they were about to run out of the race only version. I live in Texas, and we have no emission tests for motorcycles in our great state. I think S&S told me they still make the race only version, but you might want to call them and double check. My pipe was ordered on 12/30/23! Good Luck!!!
Went right out and pulled mine! I was looking for a way to give me some more rumble! I didn’t know the db killer was even in there.
Nice! How you like it now?
It sounds way better to me! I’m going to ride here in a minute and see what that’s like. I wonder if it needs a new tune now?
@@joshmann6883 nope. If anything it should run a little better
How’s the pipe position by your foot . Do you need to be extra cautious to not burn your leg ?
@@SETTAPERFORMANCE nope not at all.
@@robb907now I have to figure out chrome or black … that chrome looks awesome .. I have the black denim 2018 bob … mostly blacked out …
Thanks again for the reply and info
Video excellent! I think that the mufflers created on the dibikiller do not go very well without it. Of course the tone without it is better, but I recommend better performing mufflers. For example the Brother 2 in 1 is without the dibikier and makes an impression for the sound relative to the bass it produces, practically always. Then without the flame breaker there is no competition, with all the respect I have for Vance & Hinse muffler of various kinds. ^^
For the most part I agree with you. . I have never tried a Vance and Hines two into one set up, but I had a set of big radius two into two pipes and I loved them. Great quality and sound.. Since I made this video I settled on a Jckpot Riot and I’m pretty impressed with that. This is my video with dyno sheets for a comparison if you are interested
th-cam.com/video/OsIiKwHp63U/w-d-xo.html
I have the same exhaust on a FXBB Street bob Stage 2 with a Redshift 468 Cam. - mine sounds much better without the DB Killer. - the CAT popped out after a week though.
Just ride that sucker out is the key then. Ha ha ha that’s great! Mine didn’t have a cat because it was the 49 State version. How hard was it to notch the screws out to get the dB killer out?
I just got a 2022 lowrider st and I should be getting this exhaust Friday although it’s the 50 state legal one…I do plan on taking the db reducer out but after a year and the warranty is expired.
Just so you know, you can’t remove the DB killer from the 50 state version. It’s riveted and welded. If you aren’t in California then I would strongly suggest looking for a different pipe. I have since moved onto a Jackpot riot and through tuning and dyno testing between the TBR’s, this S&S pipe, and the jackpot the jackpot reign supreme 🤓
This the vid I did with dyno sheets th-cam.com/video/OsIiKwHp63U/w-d-xo.html
Con grays on your ST!
@@robb907 thanks. The thing is, I live in ny and the governor passed a law about exhausts and decibel’s…because 3000 people in a state of millions complained about drag racers and losing sleep.
Exhausts now need a cat also that’s why I went with this exhaust. I wanted a 2 into 1 and it was either this, the non 50 state legal one and Reinhardt.
When I spoke with the service manager at the dealership who’ll do the work he mentioned he could do the Reinhardt but the fine is 1000 if you get busted.
But hey, if I want it out that bad…nothing an angle grinder won’t handle
@@scruffycavetroll7547 3000 out of millions… ain’t that the truth 😖
@@robb907 I actually might return the exhaust.
The lowrider st is so new not even s&s is sure that the pipe won’t interfere with the passenger peg on the right side.
@@scruffycavetroll7547 ahh well if you really like that pipe you can get pass peg adapters from Revzilla. It’s a bracket for softails that raises the pegs a few inches. If you’re interested and can’t find it look for 2018 Fat Boy or I can dig through my order history.
Mine has some sort of security bolt preventing me from taking the baffle out. Can’t figure out what I need, I thought it was security torx
Sounds like you have the 50 state version which has a cat converter in it. I have heard some guys say that they grind that bolt off and chisel it out of there.
@@robb907that’s exactly what it was. Ended up drilling the nipple down, and getting a torx and getting it out. Only to find out that my exhaust has a cat inside of it. I tell ya, that was about a 6 hour job drilling that aluminum mesh out of it.
@@jaybo9044 oh man!! Way to persevere! I would’ve done the same thing
Mine is quite different than yours. I had no luck removing a cap bc of some sort of security torx head screw.
Is yours the 50 state version? From what I heard those are different
@@robb907 yes
@@paulson9616 I think I saw something where you can get that out of there. I scrolled by it because I don’t have that version. Do you live in California? Reason I ask is because I just went to a fuel Moto jackpot riot pipe. They can’t ship that pipe to California though. Finally got my dyno done yesterday and I’ll post a video on the results soon but performs way way better than the S&S piped did.
Shure you didn't get it backwards? Why is it louder with it in?
Louder with it out.
Sounds better with it in, but too quiet for my liking
I have seen guys cut the db killer in half. Not sure what the affect is. I know they are louder but not sure about torque or power
I discovered that it made more horsepower and torque with it removed. The same with my KTM 1290 super adventure and S 1000 RR.
@@robb907 thanks for the info
@@mke7876no prob!
Is this the 50 state one?
No this is the 49th state. Non-Cat. 50 state is for California compliance and has a cat and therefore the DB killer is spot welded in place from what I understand.
What crankcase vent is that on your bike???
Fueling. Check out fuelmoto.com and search vented dipstick. Spendy though.
@@robb907 Ok it didn't look like the Fueling but thanks Yea they are proud of their products for sure lol.
I heard with it out the engine will be damaged??? Any thoughts?
Not at all. You can run short open drag pipes without issue. But this pipe even without the dB killer still has a long glass packed muffler.
@@robb907 right on! Thanks
No killa!
I feel the power it took out and is anyone else noticing less power on the back break?
Yep I didn’t have this pipe on for very long
Question, had any trouble taking the cap off? Cause I took out all of the screws and its basically stuck on my end. I tried muscling it off but couldn't. Ima try a rubber mallet or something unless anyone has some better ideas? haha
It should come right out. There is a 50 state compliant. Version with a cat converter inside. This one is a 49 State compliant with no cat. Where are they weld the dB killer in place. Some folks have drilled or ground the welds to pull it out. I hope this helps. Personally, I did not like this pipe and ended up taking it off, about three or four weeks after I made this video. The pipe that I settled on was a Jackpot Riot from Fuel Moto.
@@robb907 Thanks for the feedback man!
The problem is all the new super street pipes have a special bolt now that cannot be easily removed. Tried on mine and it’s a special tool that S&S had made for them
Special bolt for what? The dB killer? Or baffle? The dB killer comes right out. Also, this is 49 state non cat in case you have the 50 state cat’s version.
@@robb907 if you get the 50 state version, not even the db killer can be removed since you can’t take the cap off. The only one that isn’t 50 state legal is their race only one which is currently out of stock
@@Maverick89 ahhh ok gotcha. Well, good to hear bc mine is for sale. I put a Jackpot on it yesterday. Too much chrome on this build. The 50 state stuff really castrates any functional usability doesn’t it.
I drilled mine out and replaced the bolts.
@@GiancarloFloyd did you remove the dB once drilling out?
You back off just when you get to the camera in both scenarios. I would have like to hear the pipe under throttle after you passed the camera.
Sorry man! That would have been better for sure. Just for update purposes, I ended up getting rid of this pipe after about one month and going with a Fuel Moto Jackpot Riot. If you like the stainless steel look, then it’s pretty decent pipe and I think they make a chrome one now but not positive. This pipe robbed a lot of torque and horsepower compared to the TBR and the fuel Moto pipe. The Fuel Moto pipe what is the best one of the three. And it also sounded the best
And they says M8's don't sound badass. My new LRS sounds as good as my '79 shovelhead Superglide. Love 'em with a 475 S&S.
As long as they continue to use a single pin crank, they will always sound like a Harley 😎💀
I’ll bet your neighbors love you. Sounds better with db killer out to me
Thanks for your input, I appreciate it. I have a Jackpot Riot on the bike now. Since I did this video I dyno tested and decided it was too low on power to try to tune. I have a video on the jackpot if you’re interested. It is a bad ass pipe. The sound and performance is the best I’ve seen.
th-cam.com/video/OsIiKwHp63U/w-d-xo.html
Out sounds more natural. In sounds tinny.
your neighbors must hate u,lol
They are pretty used to me by now🤣
It’s wierd ay it’s like it doesn’t even sound like a harley
Yes it does. Sounds like a M8 equipped Harley
The worst part of this exhaust is you gotta replace your brake pedal If you have a mid controls and the pedal that they have is this big ass ugly tractor pedal. Lately S&S has been losing me as a customer with all the stuff that they’ve been releasing with the inmates first oil pump that doesn’t come with the O-ring it is a critical part for it that Harley doesn’t sell or S&S doesn’t sell then the brake pedal the huge piece of shit that thing is I was going to get their big bore kit but I’ve kind of change my mind and I’m looking at fueling.
Agree about that brake pedal 🤣
Out.. for sure.. out
Definitely
Out. Definetly out.
L
Out!
