I just install these pipes WOW what a difference... love them, awesome sound just what I was looking for the price isn't too bad. Easy to install once I was able to take off stock mufflers (used WD-40) too easy. Now my Harley Sportster 1200 Custom sounds like a true Harley and not like a Honda. Highly recommend these pipes. (might have to remap) only thing I wish I didn't have to do. Guess it depends on the bike you have.


Put these on a 15 H-D Superlow 883L. Easy installation, great sound, and no tuning required. The sound quality is outstanding. People will sure hear me coming now. Thanks J & P for another product that can't be beat.


great fit, great sound on my 2015 72 sportster. Turns it from a sewing machine back into a Harley davison like it should be


Just installed these today. Easy to follow instructions. Only took about 45 mins. Left the heat shields off. Look bad and sound loud AF. highly recommend !


These slip-on mufflers are the best. The deep fierce tone they produce on my 883 sounds phenomenal. They also look much better than the stock mufflers. Python 3 is embedded on them so your friends won't have to ask you what kind of pipes they are. They are easy to install and remove. They utilize your present head pipes and heat shield. This is the best bang for your buck!!!!!!!!!!! Way to go Python!


Python slip-ons were bought for my son-in-laws first Harley. Loud pipes save lives. He put them on by himself with minimal coaching from me. He is a good kid, but mechanically, it is not him. Perform great. Usability-wise, if he can put them on right the first time, anyone can. Great job once again guys. If you could have seen his face when he fired her up! Thanks.


In less than 30 minutes I had the old pipes off the the Pythons on. Looks and (especially) sounds GREAT! I would recommend them to anyone who wants that big V-Twin sound on a Sportster.


Installed these Python3 slip-ons on my wife's '06 Sportster 1200C. Installation was a breeze. They look great but the most notable difference was the sound compared to the "way-too-quiet" stock muffs. They sound awesome. Deep rumble but not too loud and obnoxious. Took our first ride together last evening....she's a happy camper!!! I could actually hear her behind me over my loud pipes which I couldn't do before. Rating would probably be a 5 but it's too soon to judge how well the chrome holds up. I highly recommend these muffs for anyone who likes the staggered pipe look and doesn't want to pay twice the price for the same result(making it sound like a Harley!). Only regret: They're not available for my 05 Lowrider :(


One word "wow"---what a difference from the stock mufflers. I installed these on my 2006 xl883 sportster. Low deep rumble when bike is idling. But not way too loud when riding. 4-wheelers definitely know you're there next to them. Everyone that has heard them wants Python now for their bikes. I bought these without hearing them, but trusted the reviews on this website. Pick these up if you want that big harley V-Twin sound on a Sportster.


The deep rumble is outstanding. Everyone has something to say about how nice my sporter sounds. Best bang for the buck..(!(!


made my nightster sound like a monster! love them


sound great, sportster rumbles like a big bike


They fit perfectly!


Just finished putting the Pythons on my Sportster. WOW What a difference from the stock mufflers. Installation was very easy and the sound is awesome


If you looking for that head turning sound you need to buy these exhaust. They sound great on my 1200 Sportster. And they look great too.


Had them put on in about a hour and sounds great!


All I can say is WOW! I put these on my '06 XL883C and it's probably some of the best money I've ever spent on a cycle. The sound is incredible. Definitely worth the price. Great sound without the huge price. The hardest part about the whole installation was getting the stock mufflers off and even that was rather easy.


Great product for the price. Sounds great on my Nightster..


After I got my 07 883 I was happy then I purchaced the Phyton 3 slip-ons and I was stoked. Not the deepest sound more of a thumping, dragbike sound that not only turns heads but recieve alot of praise. Easy install and can't beat the price.


Easy to install and sounds great.


Pipes are alot louder then expected.


Amazing pipes! Got mine today and installed them right away. After installation i started the bike up to hear the sound and it was A LOT louder than i expected. I was expecting a slight increase in sound, but WOW. I have an Iron 883 and i am VERY happy i bought these for it.


Loud! wow.. did not realize that these pipes would be so loud, 5 min on my bike with these things and I still cant get the smile off of my face! easy install, aggressive sound, and great looks!


Love these pipes! Quick install, and they sound so darn good!!


Very loud. Never been mechanically talented but i figured out installation in couple hours. Worth every penny.


I had these installed on my Sportster '48, along with an Arlen Ness air cleaner and an electronic EFI unit. The sound is both deep and aggressive. Loud when you tweek the throttle. Horsepower is increased and rev limit is increased to 7000rpm. The chrome is of a very good quality, and I am glad I did not waste my money on a pair of expensive brand name mufflers that cannot compete with these.


Great sound, no remap. People think I have a1200, instead of 883...

Slim 50

Really like the sound!!!


What an improvement on performance and sound. Exactly the sound I was looking for on my 2007 XL1200L. These pipes are highly recommended.......Best part of the install is not having to remap my ignition with these slip-ons. Be sure to order the gaskets for the crossover tube....


I just finished putting them on my 1200 Sportster. I was a little uneasy about re-using my crossover gaskets because I ripped them taking them out of the old mufflers, but they turned out to work okay. THESE MUFFLER ROCK! My bike went from a stock purring sound to a "I've got a set" sound. I highly recommend them!


These mufflers made my sportster sound like a harley davidson now. If you have a sportster you need a set of these mufflers.


Wow! You can watch every youtube video of these python pipes but nothing can compare to the real thing. These babies are loud! Installation is a breeze, hardest part is getting off the stock mufflers, which will vary. My 883 sounds mean now, great service, great product!


Product is awesome!!! Good shipping time!


I installed these on my 06 Sportster 883 Low and I really like the way the bike sounds now and it looks good too. This was my first muffler installation and it would have been nice to know that I might have needed some donut gaskets for the crossover tube. I was able to reuse mine so there was no problem, but I could see if someone had more miles on their bike it would be a good idea to have some handy.


Super easy install. Bike sounds awesome. Nice deep tone. Loud but not obnoxiously loud.


my bikes sounds awesome. now I feel like im riding a Harley


I just got these mufflers on. Wow!! what a difference from the stock mufflers on my 1200 Low. Fired up my wife's Soft Tail Deuce with full V&H 2 into 1 pipes and the sound is comparable! Make sure to get the exhaust crossover gaskets before you start. Easy step by step instructions for removal of old mufflers and installation of these Python 3 pipes. The hardest part was getting my old pipes off. I rate these pipes a 10. Nice and loud, as they should be to save lives.


Nice throaty sound, easy install, pipes look good!


I love this item....And look forward to many more purchases for J&P Cycles!!!!


These pipes are great. Completely changed my 07 1200 Low to a big bike. Sound good and make the bike look good. After you fight the stock mufflers off, be sure you have a pipe expander to get these to "slip" on the head pipes. They are tight !!


More power & sounds awesome


Wicked sound. Good looks.. but.. order or go to your dealership and buy crossover gaskets.. you can't reuse old ones.. they only cost a few dollars.. one of my pipes had a small peeling piece of chrome? I didn't freak, just put that pipe on front cylinder. Use PB blaster to get old pipes off... don't rush spray it on, take dog for a walk, whatever... stock pipes twist off in your hand.. Also take stock heat shields off!! Makes it way easier. Overall awesome deal cool project and NO you don't have to re-jet if you keep stock air cleaner (just like bike on website!!) Loud when you want them to be quiet when you need them to be! Will buy more from J&P!


pipes are asome gald i bought them.pipes where here inabout two days.instalation was really easy.


After almost running over a woman in the bank parking lot, (the stock pipes were so quiet) she couldn't hear me coming up behind her and walked/turned left right into my path. I decided I needed to go louder. Enter the two and one half inch Python slip-ons. 30 minutes to switch out (45 min with double checking everything) and now you can hear me coming... LOUD PIPES SAVE LIVES and not just your own!!! Now back to the 2 and1/2 in slip-ons sound great and they blend in perfectly with the stock HD pipes and heat shields. It almost looks like straight drag pipes. Installation was simple and J&P delivery was right on even though Thanksgiving Day delayed it by one day. I would like to try the competition baffles, just to see if I can get any more low end torque, but it doesn't backfire and I didn't need to rejet the carb so don't fix it if it ain't broke. I will probably have to jet the carb when I put on a bigger air cleaner though. Thanx J&P, I got my new Z bars from you too.

Perfect fit, great sound, easy to install, very happy with my purchase


sound and performance were superior.a bit of a pain to install but that was not the manufacturers fault,just getting my big mitts in tiny space between slip-ons.


i was convinced to get the pythons after readind the reviews. like most of you, i love them. this is the 2nd day riding after installation on my heritage and they sound great. on my first ride they sounded really loud. a strong rumble and increased performance. 5 star in my book.


buy these pipes.they make a big difference.for the money you cant go wrong.great sound a lot louder than i exppected.

I've bought Python's for 2 previous bikes I've owned and was never disappointed. Had to get another set for my new bike. Easy to install and sound absolutely great.


Sounds awesome!


Beautiful, sounds great, all this at an affordable price


Easy install, sound awesome!


Finally got my pipes! But had to wait until 7:30 pm Put them I on fired them up and I realize that I had giving My baby a voice and she talkes to me nuff said!!!


Awesome sound


Easy to install; incredible sound. Worked perfect!


Incredable sound and improved performance. A litle pricy but worth it.

Unbelievable sound! Not at all obnoxious sounding. Gives the classic Harley rumble without blowing out your ears! So easy to install, I thought I did it wrong.


FIVE STARS!!! Easy installation, and Bike sounds amazing!!! I was skeptical at first about slip ons, but these are worth every penny..even look fantastic.


Put them on my 2012 street bob and they sound great. The hardest part of the install was getting the stock ones off.


These python slash cuts sound much better than I was expecting for the money. The factory pipes that came on my super glide made it sound like a volkswagon, now it sounds like a bad a** harley. I purchased them because they had good ratings, I can see and hear why now.


Took less then 30 min to install. Had no issues. Pipes are loud. I like it!! They do sound kind of hollow though. Still a very big improvement over the stock pipes on a 2013 FXDB. I would reccomend these to friends.


I like this rest of these folks put these on my Dyna an wow what a difference. The sound was awesome deep and throaty But not crazy loud enough so they can hear you. Changed to a high flow air cleaner and added a TTS mastertune. The performance is incredible. Highly recommend doing the whole package.


I received a set of these pipes as a Christmas present, and as far as getting motorcycle parts for Christmas goes, they are a winner! I had them installed on Christmas morning; took me about forty minutes, most of which was getting the old mufflers, particularly the front one, off. The Pythons went on as though they were a stock part; perfect fit! The chrome is beautiful and the welds are very neat and precise. The sound, however, exceeds the looks! These pipes have a nice rumble, and when cruising, they're loud, but not obnoxious. Under hard acceleration, however, these pipes are really loud! The sound, both at idle, cruising speeds, and under acceleration, is fantastic! A deep rumble at idle, and a purposeful growl as she cruises. Starting the engine is a treat every time. And while Vance and Hines pipes sound great, it's nice not to sound like everyone else. Performance improved slightly all around; these pipes are a nice compliment to the high flow air cleaner. While I did not need to do any jetting, I will be doing that this week in order to get the most out of them. I highly recommend this product!


Nice pipes, great fit and killer sound !!!


Easy install, first for me. anyone can do it.


I've been running these pipes for about 6 years now. They sound terrific and perform excellent. Never had a single problem with them. The exhaust note is perfect. It's not too throaty and not too raspy. It sounds like a true Harley should sound. The chrome is great quality and has minimal yellowing. I prefer the look of staggered exhaust although I still consider the increase performance of switching to a 2 into 1. However after all is said you just can't beat these for the money when it comes to slip-ons.


WOW! These slip-ons are great! Have to admit I was a bit skeptical about them, was thinking what could I possibly get for under $250.00 .... I finally gave in and ordered them. I was truly surprised with the tone of these, nice note! Best deal I have seen. Me n the Low Rider are hapy as can be.... Thank You!


First upgrade on my 2014 Street Bob. These things are Loud. Easy install if you have the right equipment. Took little over an hour putting them on. Would be faster if you know what your doing.




Great price, easy to install, solid HD sound! I would give 5 stars but the mounting bracket between the to pieces I had to drill another hole as the mounting brackets on the slip on did not fit. Otherwise, very impressed with this product!


I ordered these and got them in 2 days. Installation was very easy. Took a little WD-40 to get my stock ones off my super glide but these went on very easy. Directions were straight to the point and my Harley is a Harley now. There great. Don't think I'm putting my stock heat shields on though. It block about 1/4-1/2" of the slash cut.


Unbelievable!! Amazing sound for an extremely reasonable price. My Harley Davidson dealer told me not to waste my money - softails won't get the sound you want. Glad I didn't listen to them - IT IS the sound I was looking and listening for.


I actually bought these back in 2013 and was doing some maintenance to my bike now in 2018 and realized that at some point the baffle on my pipe and fallen out. I really do not know when this happened, but a little disappointed especially when it says the baffle is not removable.
