R18 Jekill & Hyde Install and Thoughts

Does anyone know if there is a difference in exhaust note between short and long Jekill & Hyde slip on?

For those that have them, please share your experience. I am trying to get one for my
R18 B.

Thank you!

I ordered the Beat Long Chrome with Bigshot Chrome version for my Model B; I'm expecting it before this weekend and out test riding it Saturday & Sunday... :)

I just finished my weekend project of installing the Jekill & Hyde exhaust on my R18 and since I could only find limited threads, I am posting my experience. During the 7 months of owning the bike, I have surprisingly loved almost every aspect of it, but for the exhaust. Cool looking bike with a BMW sewing machine exhaust. The J&H is what should have come with the bike from the factory in my opinion. The wide open exhaust setting is deep and throaty but with a push of a button, you can silence it and sneak into the garage without waking the neighbors. Best of all, everything is hidden and looks very OEM.

Total time from order to deliver was 14 days. Impressive given each exhaust is custom fabricated and shipped from the Netherlands. The communication, packaging, and craftsmanship is A+. Supplied directions are an A-, but hopefully the notes below will assist other in the couple of spots I needed help. Total install time took about five hours. If I had to do it all over again, I think I could cut that in half. I really wish I owned a bike table to lift the bike up and work in a comfortable position. That would have made a world of difference. Having all the necessary tools ahead of time would also have saved many trips to the basement. So let's start there.

Tools
Torx sockets in 25,30,40,45,50
10mm & 13mm socket
3mm & 5 mm allen wrench
Breaker bar (to remove the four OEM bolts that hold the OEM exhaust support in place. There have Loctite on them from the factory.
Rubber mallet (used to pound off the OEM exhaust)
Torque wrench
Blanket to lay/sit on the floor unless you have a bike table.

What I learned
- Remove the factory heat shields secure by two torx bolts. Each OEM exhaust pipe is held on by a single C clamp, but it doesn't slide off. You need to pound it off and in order to do that you need to remove the heat shield.
- Installing the servo motors threw me and I emailed Steeve at J&H on a Saturday for help. He called me within minutes. To me the directions were not clear on how to attached the servos to the bike. Steeve sent me a pic of the bolt to remove and explained that once the bolt is removed, you need to pull down on the plastic and slip the servo tab between the engine and the plastic then re-insert the bolt you just removed. Below is a picture of the bolt you need to remove. Makes sense now.
- Removing the four OEM T50 bolts that secure the exhaust support is a pain, especially on the LH side because the bolts are under the big, they are big, and Loctited in. There isn't much room to play with the shifter. I could see the probability of stripping one of these bolts as moderate. The RH side is easier because the bike is leaning in the opposite direction and there is no shifter. Still, this was the biggest pain of the project.
- The wiring was a breeze and took about 30 minutes. The button on the handlebar is easy to pop on and I snaked the wire through the existing OEM hole in the handlebar so it is concealed. Alternatively, you could zip tie it to the outside.

I could only start it up in the garage as it is 15 degrees out, but it makes me smile. Below are a couple pics of the process and to show where I ran into questions. I hope this is of some value to the next install.

I installed the J&H Exhaust Control Module within that unknown space on the RH side of the Model-B:

I mounted the Jekill & Hyde Exhaust Mode Button on the LH Side just below the fuel tank; I didn't want to clutter the handlebar tree, which already has a LOT going on in terms of distractions. I'll most likely keep the exhaust in Mr. Hyde mode; the throaty sound isn't quite a DUCATI Termignoni - nor the normal HD stuff, but way better than the sewing machine..

I know a few of us looking at the Dr. Jekill & Mr. Hyde exhaust system have balked at Wunderlich price; I looked up the BMW pricing for the parts that I harvested off of my bike from the J-&-H exhaust install. The Mufflers, Heat Shields and Case Mounting Bracket topped out at over $4,700 USD.
 
For those who want loud volume, go to Vance&Hines without the decibel killer. I don't have it, but I heard it. Excellent sound, the quality of the brand is know for everyone, and of course: the less price of all the after market r18 exhausts options

I haven't seen a Vance & Hines on a B or TC as of yet?

Thanks for posting, they look good on the bike; a nice clean line. I recently purchase & installed a Dr. Jekill & Mr. Hyde exhaust; however, I checked the V & H site a couple of times during my initial exhaust search and coulnd't find anything for the R 18 TC or B model. I'm still not sure where and how R 18 owners can purchase the V-&-H exhaust systems?

BMW only, these have been around for a while and were originally for the Classic, although V&H have been struggling to supply them I think, especially the EU versions which is what has spawned the akrapovic slip ons I’m sure. The one in the video is the US spec with the baffle removed. I saw a pic on instagram a couple of months back from an Italian (I think) bagger owner that had them fitted. The badge on the V&H pipes is smart too imo with the boxer silhouette. No option to adjust the sound obviously like the Jekylls

I'm not so sure that the adjustability of the Dr.Jekill & Mr. Hyde exhaust sound applies to me; I basically decided to leave it in Mr. Hyde mode, that's the sound that I was going for... Besides, I see the adjustable servo motors and or the SmartBox electronics potentially being a failure point; I took extra care in performing the wiring in order to avoid premature failure of the system.

Bmw dealer sells vance and hines, one of the mechanic has one on his bagger. They sound okay…..

C or A but rotated 180. I think the black tips look lost against a chrome muffler body.

I'm surprised folks haven't inverted the BMW OEM SLASH CUT exhaust tips to get a different look; it's only four Torx screws that secure them, which can easily be rotated to change the slash cut 180 degrees. This occurred to me while I was packing my OEM exhaust into the J&H boxes; I had to remove the BMW OEM exhaust tips in order to get the exhaust system to fit within the J&H box.
