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.

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!

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.

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!

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.

This exhaust is an awesome performing and sounding exhaust system. I have sold two sets to the same customer. They tune well. Our customers are satisfied.

Sales Rep was great! really nice exhaust!

I used the 15 minute video to install this exhaust on my HD Pan America. The video even has a note as to what size tool you needed for that specific job. The actual job took me about 4 hours because I wanted it perfect. It sounds and looks amazing.

Just installed the J&H exhaust on my 21 HD Sporter S. This is a very well made product. The fit and finish is better than the stock exhaust and any other for that matter. Purchasing and installing was easy. Customer service was there when needed. The 3 different variations of sounds make the bike sound great. I would highly recommend J&H for your exhaust upgrade.

I saw Jekyll and Hyde exhaust while researching exhaust for my 2021 Indian Challenger but didn't get chance to look into them more at the time. I thought they might be a good idea for me since I often ride my bike to horse rides where my wife and a lot of friends go with their living quarters trailers. I didn't want loud exhaust spooking anyone's horses. When I was at Daytona bike week in spring of 2023, I came across the Dr Jekyll and Mr Hyde exhaust trailer and listened to the bikes they had them on. They didn't have any with them to fit my bike so I ordered a set. It took awhile to get them because they had to make and ship them from overseas, but it was worth the wait! I wasn't sure how my challenger was going to sound with them but after I installed them, which went without a problem, and started it the first time, I knew they were perfect for me. The Dr Jekyll mode is actually more quiet than stock, and the Mr Hyde mode sounds great. My challenger has the sound to match it's performance now. I haven't used the dynamic mode much yet though. I want to also say everyone I have talked to with the company have been professional, polite, and ready to answer whatever questions I had. First Class crowd for sure.

Excellence in customer service. Eddie took me through the ordering process and explained all the great benefits of tis extraordinary muffler. Now I can control my exhaust tone, loud as needed and quiet when I am on the highway for extended lengths. Thanks J & H team!!

Met the Jekyll and Hyde guys at 2023 Daytona Bike Week. All friendly, knowledgeable, and helpful. Bought the exhaust system (after returning home) at the show price, so thanks for that! They said it was a one-hour installation. I watched their YouTube which was very helpful. The installation took exactly one hour. No muss, no fuss. Excellent product! Looks great and sounds absolutely awesome! I've told many fellow bikers the Sportster S is a great bike that will be even better with a proper exhaust system and so true with the Jekyll and Hyde exhaust system installed!!!

Fit and Finish were perfection! Plug and play wiring was simple. Love the sound. The finish product looks like it came on the bike from the factory.

Allen (Michigan) | March 30th, 2023
The ability to go from stock quiet to wide open is nice. No disturbing the neighborhood in the morning, but a wonderful sound rolling down the highway. The guys did a fantastic job putting the system on, leaving no detail unchecked, to even giving the bike a quick wax when done!. Look, fit and sound were better than expected! Thanks for making this system available at Daytona Bike week!
