    Sweet sweet sound!
    (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!!
    Great service

    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.
    Easy to order

    Quality Unmatched
    | 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

    replacement servomotors
    (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
    Pipes for any occasion

    A Must-buy
    (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!
    Great sound options!
    (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.

    Simply the best all around sounding and functional exhaust system on the market, have them installed on all of my bikes!
    Third time
    | 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.

    From Mild Mannered to Wild Ride: My Jekill & Hyde Exhaust Upgrade
    (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!

    JEKILL AND HYDE Exhaust 5 Stars
    (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.
    Great Service

    Astonishing Exhaust system
    (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.

    (North Carolina) | August 3rd, 2023
    I was very skeptical as to how the pipes would perform in each mode. They sound amazing and I saw no performance decline. If anything maybe better. I would like to share this with you. I was at the stop light and had the pipes wide open. And my son call and I was able to answer the phone select the full baffled. I was able to talk to him with no issue was able to use Sir. And when I was done. I open her right back up. Amazing product. It's worth the money. The shop was amazing and very professional. Great people to do business with.
    Very good service

    Outstanding product and excellent customer service
    (Greenville, SC) | July 28th, 2023
    I went up twice to Hendersonville - 70 miles one way - to make sure, that my money spent is worth it. And the team of Dr. Jekill and Mr. Hyde did not disappoint me: I got the coolest exhaust for my Harley, professionally installed in no time while waiting. Sound, quality and finish is incomparable with any other system. No retuning was required after the installation. The bike was handed over ready to ride. Torque and performance feel just like before. With the fully open valve, I can notice more low end vibration of the bike. It simulates a wilder and more emotional ride. What a blast! I don’t want to get off the bike anymore. Thank you Jekill and Hyde!

    Dr. Jekill & Hyde Exhaust
    (Clermont, Florida) | June 15th, 2023
    I heard about the J&H exhaust from my salesman at IMotorSports Indian in Orlando. When I brought my FTR 1200 in for it’s first service I had the dealers technician install the all black version after I painted the header pipes flat black myself. The system looks fantastic and is an extreme eye opening surprise for all the people I show it to. I ride my bike almost daily to work and have to ride through a couple of very small towns. The ability to quiet the exhaust down entering the town keeps me sound ordinance legal and the popo don’t give me a second look. But outside town I touch the button and am off and turning heads.
