Look great, sound great and were easy to install.


I wanted to change out the head pipes. But, I settled for just the slip on's. Good base sound. I recommend these pipes.

Great. But ordered the baffles to tone them down just a little.


very happy with the sound and delivery was spot on

These pipes sound great on my ultra limited. They took fifteen minutes to install. The quality looks very good. Good price with my gold club membership too!


Great price !!! Looks great & sounds even better. Had the old ones off & the new ones installed in less than 30 minutes. Should have done this much sooner.


easy to install sounds great and fast shipping

great sound and easy to install, check the packing to make sure the muffler hasnt gouged a chunk of the packing on the small end before installing

P Diddy

Great product at a fair price.


looks great doesn't sound the best.


sound great. hardest part of instal was getting the old mufflers off. took about 20 minutes total


This muffler sounds great.


Great product and they sound great. They are super easy to install. I would recomend these pipes to anyone out there with a Roadking.


As advertised, these slip-on mufflers were very easy to install. They sound great, nice deep rumble without being obnoxious!


Look and sound terrific.


Good job j and p. got my pipes fast. Ordering was a breeze. They were packed nice and looked great when I got them on. The sound and looks on the bike was awesome. Just what my 09 road king needed. Installing was a snap they slipped right on and no issues with anything. Vance and Hines make great stuff. Great value and price.


Awesome! sound is what was expected from vance and hines.


These pipes are a perfect fit for my 2010 FLHTK. The growl is great but the pipes tone down at highway speed. 30 minutes to install.


These slip ons are great! easy to install and makes the scoot sound much better.


Sound great. Not too loud.


Good fit and looks thought they would be a little louder but sound great.


JP cycles is the best and thanks to reviews from other patrons I was able to select the right mufflers for my 2000 Roadking classic these Vance and Hines are grrrreat...awesome recommendation..thanks everyone Paul in Canada


Great look Great sound. JP tech dept. very helpful with my selection. I'd recommend these to anyone!


fast shipping,my tri glide now sounds like a Harley ilove the sound,great buy.


very satisfied i recommended Jp &P to my friends

RK Rider

LOVE these mufflers. They made my '07 FLHRS sound like a Harley should sound. Not annoyingly loud (my neighbors haven't complained yet) but give a nice low-end rumble when you get on it. As with all V&H products, the quality is top notch. Easy to install - you'll be smiling in minutes.


Items arrived quickly and as expected. Thanks J&P!


Very easy to swap out and sound terrific.


Nice sound


Nice sound


Look great and sound great. Good deep tone that is mellow at cruise speeds. J&P very prompt on shipping and good prices.


Pretty easy to install, the sound is pretty good. It makes it so I like to turn the stereo off just so I can listen to the rumble going down the road.


Easy to install and good sound


Good look and Great sound!!


Awesome sound and looks amazing on my 02 Road glide


had a wonderful expierence

Cecil G

Looks and sounds great. A great addition to my HD Street Glide.


you can never go wrong with Vance&Hines,great sound great looks.


Mufflers sound GREAT


Love these pipes! look great sound better


Quick shipping...Very easy install and awesome sound!!! Highly recommend!!


Sound great easy to install work great with the V&H VO-2 intake and fuel pak .


Classy look not to loud. Very easy installation. Fast shipping. Best price for high quality pipes.


I put on 2014 FLHTK fit great no tuning and sound is better then stock will not be heard on phone call. Not to loud.


The mufflers came fast and took less than 1/2 hour to put on they sound good and not overly loud.


Fast shipping. Looks great and nice sound. Very happy with these. Was looking at these or Rinehart's, glad I went with these Vance & Hines.


Great sound! Not to noisy, but a lot better sound than stock. It gives you that nice V&H rumble. Also, very Easy to install.


I love these slip ons! Easy to install, look great and my Road King has that low rumble that I want!

L Boogie

These pipes are awesome. Not as loud as I wanted, but they sound great!


Easy installation on my 2014 Street Glide Special. No Fuel Pack or dyno run. Stock air intake. My bike sounds like a Harley now. No change in performance, no complaints. Very happy with my purchase and with JP cycles.


Thanks J&P Cycles. Ordering was a breeze. I ordered the twin slash rounds mufflers on monday and received them the next day. Real easy to put on and looks great on my ultra classic. The sound is great, just what i was looking for. I've had alot of compliments with these mufflers all great of coarse Thanks J&P Cycles will be doing business with you guys again.


Great slip ons. Great sound


Ordered them on Friday and they were delivered to VA on Tuesday at no cost to me. Installed them myself in an hour. Replaced stock pipes on a 2014 Electra-Glide Ultra Classic. Could not be happier. Love the low end rumble at idle and they are not too loud at cruise speeds. I can control how loud they are by how hard I crack the throttle! Thanks JP, the reviews on your site helped make the decision to go with these.


Very nice slip-ons. Great look and nice sound. Loud but not obnoxious. A noticable difference in sound and performance with V&H True Duals and Power Commander III. Worth every penny!!

kenneth porche

i got twin slash vance hines today just as they said and 1 hour later i had me a harley.installation was easy, fast,great looking and the sound is awsome.the staff was very helpful ,chat line was great,and very first




V&H slip-ons sounds great. They have a low sound and aren't very loud at idle. You can make them loud by revving it up. Cruising at 70 isn't loud at all, either. Very neighbor friendly.


Great Product and very easy install, took maybe 20 minutes of course hardest park is always getting off the old pipes. Not to bad but I have a 2014 Harley Electra glide ultra. Now it sounds like a Harley should. 100% better then stock!! fast delivery as well.


Excellent ...high quality and sound awesome... These pipes are amazing ...I got comments from other rider almost immediately ..great low tone.. Highly recommend them...THANK YOU J&P and Vance and Hinds!


Sound and look great!!!!


They sound considerably better than stock on a '12 RK with stock head pipes. The price was right too.


Great pipes, fast shipping received in 3 days. Always good shopping with J&P!


Fit and function was outstanding. I would expect nothing less from Vance & Hines. Love the deep tone and noticeable performance increase. Great price for such a quality product.




great exhaust, got them 2 days after I ordered them...Super fast delivery! I opened the box to take a look....they are going to look great on my 2014 streetglide!! Can't wait till spring to come!!


I've installed Cobra's and Screaming Eagles on my most of my bikes over the years. Awhile ago, I finally purchased and installed a pair of these Vance and Hines exhaust onto my 2001 Road King. The sound is incredible. Night and day from the stock and other brands I've tried. Plus a little added performance was way cool too and a nice suprise. I traded my Road King last year for a 2014 Street Glide, Needless to say, I just ordered these for my Street Glide. I can't wait to receive them and get them install them.


These mufflers installed on my 2011 Electra Glide Ultra Classic in about 1.5 hours. They sound great to me. Not so loud as to be obnoxious and I can still hear my radio during cruising speeds, without having to turn it up. The sound is now much more throatier and lower pitched, just what I was looking for.


pipes took about 30 minutes to install!! and made a great difference in sound!! sound great and love em so far!!


Exceeded my expectations. Very nice sound. Wife says it finally sounds like a Harley should


Great mufflers.


I absolutely love the Twin Slash Rounds Muffler! They give my Harley Ultra 103ci a great throaty sound along with added performance! I highly recommend this product to anyone who wants their bike to look and run like a million dollar machine!


Neighbors aren't happy, But I love the GREAT sounding pipes. Easy install.


The Vance & Hines Twin Slash-Cut Round Slip-Ons are awesome. I recently purchased these as a replacement for the stock mufflers on my 2007 Harley-Davidson Road King and I couldn't be any happier. They are loud but not so loud that I need ear plugs. Installation was a snap and took less than half an hour. I highly recommend these mufflers.


Took me about an hour to switch these out, most of time spent getting the old ones off; matched it with the fuel management system (that also took about an hour); bike runs smoother, more power and sounds great


great quality, nice deep mellow sound, already have true dual head pipes & V & H fuel pak. now it's the perfect match.


Was super easy to install, 3 bolts then done. Sounds awesome and according to the Harley dealer you do not need to MAP it if you just replace the cans.


Great muffler. Deep throated sound and easy installation, about a half hour to install. Best price I could find and quick delivery. Absolutely no disappointment with this purchase.


I love the difference, over stock mufflers. Now it sounds like a Harley should. Arrived fast, in perfect condition, easy install.I definitely recommend these slip ons.


Awsome sound! Easy to install. Shipped right away, were delivered within 2 days.


They were easy to install and worked as promised. The only reason for not having 5 stars is in order for the bike to run correctly I need to purchase the v&H fuel pak. That would have been nice to know. But overall better performance and a satisfied costumer.


Great product!! But I am disappointed that I bought these at the open house Rally and they were full price there and i couldnt use my dad's gold card. Should gave saved money and bought them from my livingroom. Unfortunately the rally was a bust this year.


Perfect fit along with a great sound, Brought my Road King to life.


Perfect for my 2015 street glide fit perfect took about an hour, to change from stock pipes.


Easy to install & sounds great but not obnoxious.


Awesome sound & performance! Delivered next day after ordered!


No complaints on product or J&P cycles.


Easy to install. I am disappointed in the sound as there is not much increase in loudness.


Installed these mufflers along with dresser dual header system. After tuning at the H-D dealer I gained almost 10 mpg along with better performance and a GREAT sound! Also received parts in 1 day!!


Prompt delivery, quite simple to install. Makes the bike sound great!


Just got them put on my 2015 Road Glide Special. WOW what a great sound. Deep and mello. Took just under an hour to install and most of that time was removing saddle bags and stock exhaust. 3 day delivery. Thanks J&P!


Perfect fit and sound. Very easy to install.


Very good product, was extremely easy to install. Sounds great!


I'm happy


Awesome deep rumbling sound! Free shipping to my door in 2 days still cheaper than local HD dealer. Installed in about 15 minutes. Took longer to get pipes out package. Nice job packing these babies......kudos all around!


The exhaust looked fantastic in the box ... V&H makes a great product, but they sent two left ones. So for "quality of the product" 5 stars for "quality control" zero stars. I returned them and now waiting on another set. I'll re-visit this when I get them on the bike. I believe it will go back up to 5 Stars I'll wail and see.


After a long and expensive search, I finally found this exhaust with the perfect exhaust note -- plus a little pep in power. Nice. I'll be putting even more miles on the bike for sure.


Very easy to install and they look great, but I'm not impressed with the sound. 2015 Road King. They sound okay when you're on the throttle, but at idle, they sound basically the same as stock.


Wow! Great sound! I've never installed slip on pipes prior to these. Installed them on my 2015 ultra classic. Very easy! About 30min total! Lots of compliments! Huge difference in sound. If u wanna sound like a Harley don't hesitate. Thanks J&P


Very easy to install and they sound great.


These slip ons were well made. Easy to install. Gives the bike a little more tone to the sound. I also added a high air flow filter and the fuel pak. Noticeable difference in performance. Don't seem to have as much heat from rear cylinder. Very easy to install and fuel pak is very easy to download program and install as well. Highly recommend.


Just what the Dr ordered...'01 Raod King with stock mufflers was almost an embarrassment to ride...Just didn't sound right...Installed the V&H Twin Slash and it really came to it not only looks and rides sounds like a Harley should...easy install and WELL worth the money...can't go wrong with V&H...


Quick and easy way to relieve your bike of stock Prius pipes. I have experience with V and H pipes on my previous bike. Great outstanding looks and workmanship. The slash pipes have a nice deeper rumble that are not going to get you kicked out of your neighborhood, but will bark well when someone is cutting in front of you because they didn't check their mirrors. Might be a slight power gain, since you can actually see through this pipe, but I am more interested in the sound. Install was easy, there are several videos on YouTube for this product and one on the j&p website as well. I'm mechanically enclined and it took me about an hour being careful. You got this.


Awesome slip on mufflers! Great quality, perfect fit and exactly the sound I have been looking for on my 98' Ultra Classic. Should have bought these a long time ago. Also, I got these delivered ahead of schedule by J & P. Thanks guys!


Very quick shipping. Easy to install. I did have to muscle my old mufflers off, but installing the new ones was easy. They look and sound great. Super easy to tune with the Fuelpak 3 that I bought with them.


Look great, sound great, and with the FP3 and the performance is awesome.


excellent in every way good sound great chrome easy install


Quick shipping, easy install. Great looking and sounding pipes. Along with Big Sucker Stage 1 kit and FP3, nice performance boost


Looks great, sounds great easy to install


Looks good sounds good


don't wast your money if your looking for deep load mufflers.and if you have a problem getting the baffels out vancen hyne wont stand behind there product.


if your looking for loud mufflers you will be disappointed.they are no louder than stock mufflers.and if you have a problem getting the baffels out to change them vancen hyne wont stand behind there product.


Quality product, Great sound, great look, easy installation!!!


These slip on mufflers are awesome. The are in fact louder than stock and they get louder when you put more miles through them. I get compliments all the time. If your looking for them to be louder I would suggest the purchase of headers.


Pipes really sound great. Very easy install. Item came as promised with no damage or defects.

Paul Ouellette

Great looking chrome and easy install on a 2010 Road King. If you're looking for a set of pipes to give you more rumble and growl than stock without upsetting the neighbors than these are the ticket.


These sound good and add performance. Not so loud until you get on the gas. Perfect!


Perfect fit for 2017 Street Glide Easy to install, extra hardware came with shipment. Deep throaty sound for the 107 Milwaukee 8


Awesome mufflers !!! Just what I was looking for. Nice, Harley, low rumble. Louder than stock, but not obnoxious, which is just the sound I wanted on my 2017 Ultra Classic !! Only took a coupla sockets and 30 minutes to install, and I'm no mechanic. Super satisfied and now I'm not embarrassed to crank my bike up anymore !


3rd set I've had on as many Harley's. Great looks, performance and sound.


Easy installation. Nice deep sound. Louder than stock but not too loud. In fact any louder would be too much. The twin slash looks great.
