Michael (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!

EXCELLANT PRODUCT AND SUPPORT
Dennis Garcia (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.

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!
GT Ford (Pennsylvania) | May 20th, 2023
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.
William (United States) | May 10th, 2023
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.

Tom Atzert (Mooresville, IN) | April 16th, 2023
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!!!
Brian Joseph Brown (Earth) | April 12th, 2023
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.
Jose | April 4th, 2023
excellent buy
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!
