VINCE (NEW YORK) | September 17th, 2024
The gentlemen I spoke with went above and beyond for me making sure I get the right exhaust on my bike.
Ive purchased already two other exhaust systems from other manufactuers and once received they were either wrong or missing items. Feel extremely excited for this one feel big man upstairs deterred me from those to do things right the first time and purchase this exhaust here. thank you fellas!
Kasey James Kadrmas (Florida) | September 5th, 2024
I spent ages doing research on the perfect exhaust for sound and looks. This is THE one by far! I Love it!!!
Guillermo (México) | September 2nd, 2024
Great sound. The ajustable valve is really helpfull when you want to reduce noise. Engine feels 20% cooler.
Tom Edwards (Wisconsin) | August 16th, 2024
that was the easiest way to order so far.
David Peloubet (Fort Worth Texas USA) | July 16th, 2024
Great product. Works great. I am disappointed that a custom made product doesn’t have the logo mounted where they square up together with street. Both face down at the street
brad h mengel (pennsylvania, USA) | July 14th, 2024
I just ordered Nomad exhaust for a HD PanAmerica, can't comment on the exhaust itself yet but being able to order it online direct to myself and use PayPal to complete the purchase was super nice.
Eddy (Longueuil, Québec) | July 12th, 2024
A little pricy but Great Quality and fast shipping...
Wayne H. Crotty (Jasper, Fl) | July 4th, 2024
The ability to turn on and off the rumble is surprisingly impressive!! Thanks for making my 23 CVO a Harley!!
Nate McElhaney (Florida) | June 5th, 2024
I bought a new Harley and they set me up with the correct wiring for transferring the pipes to the new bike. I love how I can ride loud or softer for my daughter.
Robert Dépatie (Montreal canada) | June 1st, 2024
Web site is great
David Greene | May 24th, 2024
Wow. Love this exhaust system. first of all the sound when it’s in the rumble mode is perfect. People know when your coming and heads turn and try and get a look at what your riding. Then you pull up next to them hit the button and the next second your bike goes into docile mode. But I have to say the quality is absolutely the apex of engineering. I put the system in myself and it took about an hour and half. The video on the internet walks you right through it. The manual that comes with it is one of the first ones that actually spells it out simply. I worked with Chris on getting it delivered to me and they couldn’t be any nicer but actually extremely knowledgeably about what they are selling. I would highly recommend this product to anybody who wants the best system on the market. David
Rick (San Diego) | May 23rd, 2024
timely email responses and easy ordering and payment process without issue.
Pieter Hartog (Costa Rica) | May 13th, 2024
I installed my J*H exhausts back in 2015 on my HD Softail Classic Heritage. After almost ten years driving in tropical conditions one of the servomotors failed. After on-line consultation with the factory it was recommended to rather change both servomotors. Same were ordered on-line and arrived without problems in Costa Rica and have in the meantime been installed. Excellent customer service & after sales service and will continue to support this brand for many years to come
Keith (Lowell, MA, USA) | May 10th, 2024
These pipes truly live up to their name, going from loud to stealth with push of a button. Highly recommend!
Matthew (Dallas TX) | May 1st, 2024
From the moment the Jekill and Hyde exhaust arrived, I knew I was in for a treat. The packaging alone set a high standard—pristine condition with an impressive presentation that promises quality. The contents inside did not disappoint. The installation process was a breeze; the instructions were as clear and straightforward as assembling a set of Legos, which speaks volumes about Jekill and Hyde's commitment to customer satisfaction.
The true joy came with the first roar of my Triumph Speedmaster after installation. The sound is absolutely fantastic—deep, rich, and exactly what I was looking for. It's clear that Jekill and Hyde take immense pride in their craftsmanship, and it resonates with every rev of the engine. I'm thoroughly pleased with this purchase and I'm certain that my future bikes will be equipped with Jekill and Hyde exhausts too. For anyone looking to enhance their motorcycle's performance and sound, this product is a definite must-buy, you will not regret it!
Jason Blackburn (Massachusetts) | April 30th, 2024
Excellent craftsmanship!
Installed on a 2024 Fatboy 114. This exhaust is by far the best sounding exhaust when in Hyde mode. I’ve listened to every exhaust and have owned several. This one sounds angry in Hyde mode.
Dynamic mode sounds real nice too. Great when you want to relax or take the lady on a nice ride.
Jekyll mode is good for neighbors you don’t want to aggravate BUT like I said put it in Hyde mode and bike sounds like a beast :)
Ascetically, the exhaust looks great on the Fatboy as well.
Great customer service too, I reached out to them to work with my Harley Dealer and they shipped it to them for the install.
Tomas (Atlanta, GA) | April 25th, 2024
Simply amazed at how this J&H exhaust system drastically changes the character of this motorcycle. Super impressed and happy with my purchase.
John (Florida) | April 25th, 2024
Simply the best all around sounding and functional exhaust system on the market, have them installed on all of my bikes!
Jack | April 23rd, 2024
I stand by the Exhaust from J&H as a domestic peacemaker. This will be my third. It works exactly as advertised, and I have been a completely satisfied customer. It all depends on what you are trying to achieve, of course, but if your ultimate goal is stealth when appropriate and a roar when unconstrained, then this is the exhaust for you.
Mike (District Harley Davidson) | April 17th, 2024
Great company from our first contact all the way through the delivery and packaging of the product. The customer is thrilled with the system and has no worries in taking his bike back to his country where they are very strict on sound compliance.
Texoma (Sherman, Texas) | April 2nd, 2024
keep it up
Gene (Greenville SC.) | March 15th, 2024
The sound of this exhuast wasvery good. I visitedthe both at Daytona. I am waiting to hear them on my bike.
Rickey (HAMPTON ROADS HARLEY-DAVIDSON YORKTOWN VA) | March 7th, 2024
awesome customer service
Hoff (Saint Louis, MO - USA) | February 5th, 2024
My Indian Pursuit isn't just a commuter, it's a long-distance companion. Looking back, the only regret I have is not outfitting it with the Jekyll & Hyde exhaust system sooner! Believe me, it's a game-changer.
From the initial contact with Chris in Hendersonville to the moment I roared out of town, the entire experience was exceptional. Chris answered all my questions promptly and expertly, making the decision a breeze. Installation was seamless – my local dealer paired it with a Stage 2 engine upgrade, and the technician couldn't stop grinning when I asked if it was ready. "You're gonna love it," he assured me, clearly as impressed as I was. (Apparently, it was their first J&H install, and they were having a blast with it!)
Part of the reason I chose Indian was the stock exhaust's low rumble, perfect for cruising through quiet neighborhoods. But the option to unleash some beastly roar was too tempting to pass up. Let me tell you, I have zero regrets! Every time I hit that button, the subdued purr transforms into a chest-thumping, low-frequency rumble that puts a giant grin on my face. It's the ultimate Jekill & Hyde experience – switching from stealthy cruiser to attention-grabbing machine in a heartbeat. This company lives up to its name in the best way possible!
Sebastian (argentina) | January 23rd, 2024
Excelent platform, very fast and reliable to buy from you, astonishing products!
Andrew (Canada) | November 28th, 2023
They found a system for my bike event tho it was older and not listed on there web site anymore. Very easy to deal with
Dealer (Power Motorcycles USA (Palm Bay, FL)) | October 13th, 2023
Accessorize your bike with an exhaust that fits all your needs. No longer do you have to wake up the neighborhood with that new exhaust or be that guy with the "sewing machine" sounding exhaust.
Al | October 10th, 2023
A very exciting exhaust product!!
Jeremiah Schiessel (Detroit,MI) | September 20th, 2023
First off, other than the awesome fact that you can control the exhaust to be quiet or loud, the performance of my bike (Sportster S) is convincingly better. It is almost as if the exhaust has added a new mode between road mode and sport mode. Acceleration feels more sporty and responsive (similar to sport mode) but while still in road mode than with the stock exhaust. I wish I had got before and after install dyno numbers. The look is awesome!! When it arrived I was so impressed with the level of care and detail to packing this thing I felt bad removing it from the box. Installing it is easy if you have a basic mechanical aptitude. I am truly impressed and it is the crown jewell of the bike for sure.
Gabriel Godin (Sudbury Ontario Canada) | August 30th, 2023
Very satisfied. Fast shipping 7 days door to door from Netherlands. Product as described and easy install. Jekyll mode similar to stock but Hyde rumble is sweet!
Scott (Utah) | August 17th, 2023
Although the install wasn't difficult I needed a replacement part, they were easy to work with and sent the part quickly. The service was great!
Dubé Paul (Montréal Canada) | August 14th, 2023
Very professionals services
I recommend them all the way!
