Another Free Video For Bikers By Bikers
VIDEO & REVIEW-I have owned many Vance & Hines headers and mufflers over the years and have always been pleased. There are many differences between pipes/mufflers in regards to performance, sound, and looks. This is one of the biggest decisions many bikers make after they get their new Harley and it can be a bit stressful as we all know this is not a cheap investment.
Changing out your exhaust and then your air intake are two things that will greatly increase performance and sound.
Please know that whenever changing exhaust system components and air intakes you will need to remap your electronic fuel injection (EFI), so that your motorcycle runs optimally. Don't worry, we have you covered with everything you need to know about how to remap your fuel injection.
In this video we look at the Vance & Hines Dresser Twin Slash Round mufflers in comparison to the stock mufflers that came on my 2014 Harley Davidson Street Glide Special.
I have the video set up, so that it quickly goes back and forth between the two mufflers, so you can truly get a sense of the sound quality and differences. Use HEADPHONES/EARBUDS to view this video, so you can get a true sense of the different sounds.
Free V&H Twin Slash Rounds Video
I ran V&H chrome Big Radius pipes on my 2005 Harley Davidson Wide Glide. On my 2011 Harley Davidson Street Glide I ran the V&H chrome Big Shot Duals.
Both the Big Radius and the Big Shot Duals were great pipes if you want sound, but are not the best choice for performance if you care. And wow, do they have sound. They definitely fall in the category of “loud pipes save lives”. It is not a joke when I tell you that driver’s of cages here you coming for sure. The Big Radius is just simply a bad ass looking pipe. I prefer the Big Shot Duals for a touring model Harley Davidson.
The Big Radius pump the sound out the right side of the motorcycle towards the ground. For that reason, other riders tend to not like riding on your right side for long distances. The Big Shot Duals pump all the sound straight out the back. And for that reason, other riders tend not to appreciate riding behind you for along distance. Just my personal experience when I ran those two systems and it all depends on what type of riding you are doing. All pipes have their place.
For my 2014 Harley Davidson Street Glide Special (FLHXS), I chose to change things up, but still wanted to stick with Vance & Hines. I wanted a quality sound, but without being obnoxious & without loosing power. I desired to have my Harley sound like a Harley with a lower pitched throaty sort of sound. You know, like Harley’s used to sound before they were made to put all kinds of things inside them like catalytic converters (cats) and large baffles blocking the stock muffler/pipe inners. These poor Harley’s are robbed of their true performance capabilities, because of things like this.
Anyways, I looked around the internet and watched some YouTube videos on different Vance & Hines mufflers, but none of the media were of great quality. I had never heard the Twin Slash Rounds, as nobody I ride with has this exact model of muffler.
I took the leap and just ordered them. I liked how they looked and was alright with the price. I went with my gut and the description that Vance & Hines wrote about the mufflers. I ordered these particular Twin Slash Round Slip-On mufflers through my local Harley Davidson dealership for $399 + tax. They go for $424.95 on the Vance & Hines website, so I got a bit of a break.
It took about 30 minutes to take the stock Harley Davidson slip-on mufflers off and replace them with the Vance & Hines Dresser Twin Slash Round Slip-On mufflers.
Immediately after installing the Twin Slash Rounds I remapped my EFI for optimum performance. You will want to do the same and we have you covered on that subject and how you should proceed.
After I found a lack of information on this product, I wanted to write this article, conduct a review, and produce a thorough video for other bikers considering purchasing the Twin Slash Round Slip-On mufflers.
I am extremely happy with the Twin Slash Rounds. The sound was exactly what I was looking for, that true Harley Davidson sound. They are lower pitched and throaty, but far from obnoxious. When you give it the gas and run through some gears, they really have an awesome sound that you will not be disappointed with! A sound that won’t annoy the riders behind you, but that will let people know it is a Harley Davidson motorcycle.
As far as the headers go, I was able to get an used set on the internet without catalytic converters (cats). If you want to open up your headers then V&H also sells new header systems that don't have cats in them. This will definitely increase horsepower and reduces heat on the rider. Check with your state and local laws reference exhaust. Don't worry, we have you covered if you want to save money and install your own headers and mufflers.
The chrome on the Twin Slash Rounds is absolutely beautiful and the mufflers are machined to perfection. In true Vance & Hines fashion, the mufflers are of the best craftsmanship. The overall look of the Twin Slash Rounds coming out from beneath the hard bags is a really great look. There is something about that angled cut on the ends of the mufflers that I have always liked. The Vance & Hines logo is engraved on the top of the mufflers at the very rear.
Vance & Hines does sell a quieter baffle for the Twin Slash Round mufflers, but I don’t find that will be necessary at all. I would not want them any quieter. I can listen to my Boom Box Infotainment System no problem at freeway speeds, but still hear that awesome Harley Davidson sound behind me! And my friends aren’t afraid to ride behind me when I’m in the throttle heavy.
I sincerely hope that this review blog and video will help bikers/motorcyclists make an educated decision on whether to purchase the Vance & Hines Dresser Twin Slash Rounds Slip-On mufflers.

I am getting a limited soon and want to change exhaust before I take delivery. Do I leave the air cleaner alone and just add say Rinehart black tips or do you think I should go all out and get dressers duals with SE AC, SE tuner, new head pipes and mufflers. What pipes would you go with? I currently have the slash slip ons with complete stage 1 exhaust on trike. The limited is amber whiskey and black.
Ryan Urlacher says
Thanks for your comment and I’m super excited for you getting a limited!
I always think you should at least put a stage one air intake on every new Harley or in other words; an aftermarket high flow air intake. Stock Harley’s always starve the engine for air, because of EPA crap. Yes the 2014 models too, even though it looks bigger. Inside is bigger and the air filter is very tiny, thus starving the engine for air. I’m thinking of putting a Kuryakyn Chrome Mach 2 on my Street Glide. Just haven’t made a final decision yet.
You can either have you Harley Dealer put a download into your ECM (Engine Control Module)(About $200) to remap your fuel injection or you can buy something like a Dyno Jet Power Commander V and have the download installed before it delivers. Then you just have to install it on the bike. I would get new headers, as the stock ones have the catalytic converter in them, which really holds your motor back and puts a lot of heat up on you. Vance and Hines headers don’t have the Cat and are free flowing. I already had a set of headers without Cats. I love the V&H Twin Slash Rounds slip on mufflers, but any V&H mufflers are good. Hard decision for sure. You might also look at the CFR slip on mufflers, as I really like those too.
If you don’t know how to do this work yourself, you can save yourself some money. I have a tutorial video for completely removing your exhaust and putting after market headers and mufflers on. http://www.LawAbidingBiker.com/Exhaust
I also have a video on removing your stock air intake and putting a Harley Davidson Stage One intake. http://www.LawAbidingBiker.com/StageOneIntake

joe b says
Am I reading this right? You ALREADY had the cat removed and new headers installed BEFORE you swapped out the mufflers?? Im asking because I’d like to change the sound of my 2013 ultra classic but do not want to put in the headers right now. The Slash rounds sound great on your sg but Im thinking thats due mainly to the opened headers?? I’d love to get rid of the sewing machine sound on the stock pipes but not at the cost of re-mapping right now.
Ryan Urlacher says
Joe; Having the cats out will improve sound some. The significant change is getting rid of the stock muffler. Having the cats benefits performance more than sound. I hope that answered your question. I’ve heard the Twin Slash Rounds on Harleys with cats still in. They sound much better than the stock pipes. They really suffocate the bike with those stock mufflers. Ride Safe!
Good stuff Ryan. I really enjoy your blog and videos. I have a 13′ SG, barely over 1k on it, I also want that Harley sound that V&H can produce. My deal is, after ordering twin slash rounds, I listened to RCX haust and liked the growl, lower rumble they produce. What’s your take on RC components slip ons?, Thanx, ride safe man, Ed
Ryan Urlacher says
Thanks for the comments Ed. I have heard nothing bad about RC Components, but I don’t have any personal experience with them. I was very torn when I bought slip ons. My personal second choice would have been the CFR exhaust, but that is just my taste; http://www.cfrmotorcycles.com/
Hope that helps brother!
Joseph Reyes says
Hey Ryan, you guys are putting some awesome stuff out there! Keep up the good work! My question for you is what air breather did you go with on your 2014 SG? I myself have a 2014 SG special in denim black and looking to change out exhaust and air breather. I’ve pretty much made up my mind on V&H dresser duels and CFRs. I’ve also decided to go with the dynojet power commander V. Which I’ll defiantly be purchasing your installment video.The only thing I’m not sure about is the air breather. I like the Roland Sands Design black ops turbine air filter, just cause it looks good. I’ve read some bad reviews about it filling up with oil and it leaking. I want to get your thoughts on everything. Thanks and again, keep up the good work.
Ryan Urlacher says
Thanks much for the kind words and for taking the time Joseph!
I actually like the stock air intake on the SGS and am going to leave mine as is. My SGS has great performance with the V&H Twin Slash Rounds ( https://www.lawabidingbiker.com/twinslashrounds), EFI map download, and the air intake. It just runs so great and I don’t mind the looks of the stock intake. On past bikes I changed the air intake for some performance, but mostly looks. Unless I did something more to the bike I don’t think any aftermarket intake is going to give me any performance I would notice. It would be strictly a “looks” deal if I ever change my mind.
Hi Ryan…I’m in the process of purchasing my first tour bike, which is a ’14 SG. Was looking at the Twin Slash Rounds slip ons but wasn’t sure if that’s for sure what I wanted. This video helped A TON! Thanks so much for posting.
Ryan Urlacher says
Awesome Ty and thank for the feedback.

Do you remove the baffle packing from your Twin slashes and if so how is that done?
Matt Couchman says
There is no baffle packing in the twin slash rounds. Only a perforated metal baffle. They are very free flowing. The metal baffle adds the need back pressure. They do make a quiet baffle for the twin slash rounds if you are looking to tame them down.
